Hello everybody!!! Sory for my bad english( I'm trying to write my custom screen driver for Qt on QNX. My question is where to place my plugin? I wrote stub for plugin which simply must print "Hello" on console. After i wrote QScreenPlugin class which exports my driver with name "glesdriver" (implementation of QScreenPlugin in attachment). Then i compile plugin to so library. After I place my drver in catalog /usr/qnx650/target/qnx6/x86/usr/lib/qt4/plugins/gfxdrivers. After all I'm trying to run qtdemo with my driver: ./qtdemo -qws -display glesdriver But Qt returning with error: glesdriver: driver not found I'm interested in where to place screen driver in Qt for QNX, and where are standart screen drivers placed?

To the QNX Community. I'm interested in hearing from other developers who are interested in developing with Qt, but using the QNX system as a self hosted environment without resorting to using a separate target device. You can contact me about this at maschoen@pobox.com. What I hear from QNX is that Photon is going away after QNX 6.5.0 and therefore for most practical purposes, so it self hosted development. I'm of the radical opinion that the best development tool provide by QNX is self hosted QNX and so I'm taking steps so that I can continue in that direction. The first two steps I've taken are as follows. I've ported Qt version 4.8.2 to QNX 6.5.0. I've done this using just a QNX system, not resorting to the documented use of Linux. If anyone else is interested in how I did this, please let me know and I will provide details. I've also enhanced this version so that it can support running Qt programs under Photon. The implementation is flexible, and the same modules can be run with or without Photon without recompiling. The attached jpg shows two Qt demo programs running both with and without the Photon Window frame. Currently I only support 32bit ARGB video mode. Also, note that when in the Qt window, Qt provides the cursor image. This leaves a cursor visible in the Qt window at all times, even when the system cursor leaves the window. I am looking into additional steps that make it possible to continue to develop in a self hosted manner once QNX 6.5.0 has been superseded.

Hi Dennis, first of all thanks for the answer. >>You need to make sure the armle-v7 libraries from "qt_qnx_2011-02-24b.zip' >>found at http://community.qnx.com/sf/frs/do/viewRelease/projects.qt/frs.binpkg.targets >>are installed on your target - either on an SDcard you mount, or put them in your .ifs build in Momentics.

With this you mean that i have to put the libraries on the sd-card and refer in the BBxM-buildscript to this libraries/install them at start-up? Can you give me the buildfile for the sd-example for reference? At the moment i am reading the "QNX Neutrino Realtime Operating System - Building Embedded Systems" for a better understanding in working with bsp´s and QNX and (i hope) in combination with the buildfile i can understand this better. ---------------------------- >>>>>can I use this cEasy binary for BBxM? >>No. It would need to be re-compiled using the BB native tools. Sorry that I have to ask this, but what do mean by "BB native tools"? I searched in the internet for this, but i can´t fully grasp the meaning.. this is more a language problem.. i am not soo bad in english ( I think), but I don´t get this one..

You need to make sure the armle-v7 libraries from "qt_qnx_2011-02-24b.zip' found at http://community.qnx.com/sf/frs/do/viewRelease/projects.qt/frs.binpkg.targets are installed on your target - either on an SDcard you mount, or put them in your .ifs build in Momentics.

If you are talking about Qt libraries, the reason is that the example image probably uses Qt 4.8.2 instead of 4.71 as posted on Foundry27. You can build the newer binaries from the main Qt repository.

There is only one layer (according to the output) and I suppose Photon is occupying it. Try logout of photon to text mode before you execute the cEasy command line.

Hello I have tried to build the cEasy example on a self-hosted QNX 6.5 development environment. For this I used: http://community.qnx.com/sf/discussion/do/listPosts/projects.qt/discussion.general.topc20245 and followed the instructions given in the pdf. I use Windows 8 as Host and for the self-hosted machine VMWarePlayer. When I try to execute step5 on page 7 (# ./cEasy -qws) then I get the following output (and error): >>QQnxScreen: Attached to Device, number of displays: 1 >>QQnxScreen: Attached to Display 0, resolution 1024x768, refresh 60 Hz >>QQnxScreen: gf_layer_attach(0) failed with error code 8 >>qnx: driver cannot connect >>Abort (core dumped) It cannot connect to my display? what could I do? installing another driver? ------------------------------------ And a second question: If I get the binary for a Qt Project with the method from above or wtih this method: http://community.qnx.com/sf/discussion/do/listPosts/projects.qt/discussion.general.topc21459 What am I supposed to do with the binary if I want to get this project/program working on a Beagleboard-xM? I found this example: http://community.qnx.com/sf/discussion/do/listPosts/projects.qt/discussion.general.topc20735 and this is working well, but what should I do if I want to start with the original bsp? I also found in the resulting bin order other qt program binaries with different size?? Where do I get these? I want to understand the process but I cannot find documents for this kind of topic (including project binaries in a bsp). Does someone know good documents (maybe if you have worked on a similar project). I hope you/someone can help, so that I can finally start to make my own programm on my Beagleboard-xM with Qt (Ihave so much ideas...) :D

Dennis, FYI The font issue was due missing .ttf fonts in /usr/photon/font_repository also FYI to get the mouse running required QWS_MOUSE_PROTO=qnx:/dev/devi/touch0 noting that most documentation doesn't mention the device path being required perhaps because this is a touchscreen mounted outside of io-hid Conclusion iMX28EVK from Freescale does support Qt albeit in limited form. Many thanks for your patient assistance. Roy.

Dennis, I have (and always had) the font files in place. Here is some detail:- # ls -l /usr/photon/font_repository total 93 -rwxrwxrwx 1 root 0 210 Mar 19 2013 fontdir -rwxrwxrwx 1 root 0 12393 Mar 20 2000 pcterm12.phf -rwxrwxrwx 1 root 0 12905 Mar 20 2000 pcterm14.phf -rwxrwxrwx 1 root 0 17437 May 31 2004 pcterm20.phf -rwxrwxrwx 1 root 0 2817 Mar 17 2003 phcursor.phf # cat /usr/photon/font_repository/fontdir pcterm12,.phf,PC Terminal,12,,0000-00FF,Nf,6x12,13K pcterm14,.phf,PC Terminal,14,,0000-00FF,Nf,8x14,13K pcterm20,.phf,PC Terminal,20,,0000-00FF,Nf,10x20,18K phcursor,.phf,Photon Cursor,0,,E900-E921,Np,32x31,3K I have tried altering PATH to point to each of the subdirs again with no change. Is it that qtdemo which would normally be started first performs some setup? Otherwise am I missing an environment variable perhaps? Roy.

You need the font files themselves! For 4.7.1, Qt seems to use photon fonts - you must supply this directory /usr/photon/font_repository and its files. For 4.8.x versions I populate only /usr/local/Trolltech/QtEmbedded-4.8.0-arm/lib/fonts

vsync running is enough verification of the graphics. If the fonts don't load, maybe they are not found on the target?

Dennis, Crossed over responses there. Yes, vsync does run egl-gears doesn't # egl-gears Couldn't find a compatible frame buffer configuration on layer 0 # egl-gears-lite Couldn't find a compatible frame buffer configuration on layer 0 I have one query re mainwindow as it doesn't show the text in the headings. I run it and get the responses as follows:- # mainwindow -qws QQnxScreen: Attached to Device, number of displays: 1 QQnxScreen: Attached to Display 0, resolution 800x480, refresh 60 Hz QFont::setPointSize: Point size <= 0 (-2), must be greater than 0 QFont::setPointSize: Point size <= 0 (-2), must be greater than 0 QFont::setPointSize: Point size <= 0 (-2), must be greater than 0 QFont::setPointSize: Point size <= 0 (-2), must be greater than 0 QFont::setPointSize: Point size <= 0 (-2), must be greater than 0 QFont::setPointSize: Point size <= 0 (-2), must be greater than 0 QFont::setPointSize: Point size <= 0 (-2), must be greater than 0 QFont::setPointSize: Point size <= 0 (-2), must be greater than 0 QFont::setPointSize: Point size <= 0 (-2), must be greater than 0 Roy.

>>> libQtDeclarative.so.4 => /proc/boot/libQtDeclarative.so.4.7.1 (0x1200000) Your last post shows you are loading a QtDeclarative app. I believe if you find a "legacy" app the library requirements will be much lower.

>>>I am not running a Photon system which I believe would be required for vsysnc. Roy, vsync and opengl apps like egl-gears write to "gf" directly and do not require photon. The reason I suggested these kind of apps was to make sure that "gf" graphics are functioning correctly on your test target. They are sort of a pre-requisite for Qt functionality. (Note vsync requires two layers - not sure of your target - but I egl-gears should work on one layer.) >>>I am also only trying to mount the prebuilt Qt apps Are the apps "debug" versions? A debug version can be several hundred kbytes while a stripped version is usually ten's of kbytes.

Dennis, Thanks for your response. It is certainly interesting to see the amount of memory required to run even simple apps. Re your comments, at present I am not running a Photon system which I believe would be required for vsysnc. I am also only trying to mount the prebuilt Qt apps and I am not building apps from source yet. Essentially then I am putting the ifs together for a demo of Qt. Everything seems to point to lack of lib space hence my interest in determining if any other users are running on imx28. A QNX ticket has confirmed the 32M limitation but the libs seem to fail on a cumulative total of 18-22Mbytes of dll size. Perhaps there is an internal limit to the amount of dll space which could be increased? It does seem however the iMX28 is probably not man enough for the job. However if you have any revelations I would love to hear them! Many thanks, Roy.

Roy Marsh 2013-03-19T09:29:07Z Dennis Kellly http://community.qnx.com/sf/go/post99972 2013-03-18T22:23:38Z 2013-03-18T22:23:38Z

Roy- I suppose it may be possible you are running into the 32M per process limit. I took a look at physical memory use on beagle-xm. With cEasy (or qTstat or aMeter or speedo) running on beagle, physical memory use goes up by about 30M. With webvu (webkit) on beagle memory use goes up by about 46M ! It looks like you 'might' squeak under the ARM 32M virtual address limit (pre-arm-v6) if you use QtDeclarative. However, without QtDeclarative, memory demands should be lower.

Dennis Kellly 2013-03-18T22:23:38Z Dennis Kellly http://community.qnx.com/sf/go/post99967 2013-03-18T20:21:30Z 2013-03-18T20:21:30Z

Roy- Sounds like you have the basics. Does "vsync" run on your board? Dennis

Hi Dennis, Yes I have put the binaries in their correct directories. For mx28 I use the armle. For the printout with this post I had the objects on a usb stick for convenience of testing but I have built it in an ifs and had the same result. I am literally using only the libs and built programs supplied in the qt_qnx_2011-02-24b.zip The bsp for the EVK board is straight from the QNX bsp's and the ifs is built with the QNX system builder. My IDE is 650 (not the SP1). I have also built an iMX53 on a different EVK with the armv7 libs and that works and presents a screen for qtdemo and mainwindow so I know I've got the right structure. Thanks.

Roy Marsh 2013-03-18T20:18:32Z Dennis Kellly http://community.qnx.com/sf/go/post99964 2013-03-18T19:27:36Z 2013-03-18T19:27:36Z

Just as a sanity check, you have installed the "arm" libraries, and not the armv7 libraries.. ?

Dennis Kellly 2013-03-18T19:27:36Z Roy Marsh http://community.qnx.com/sf/go/post99961 2013-03-18T17:09:51Z 2013-03-18T17:09:51Z

Has anyone run the prebuilt objects on the fREESCALE imx28evk? I can get the system to start loading a demo (eg 'mainwindow') but it appears unable to complete loading the dlls required. The process stops as follows (using ldd to illustrate the laoding problem):- # ldd /fs/Qt_mx28/embeddeddialogs /fs/Qt_mx28/embeddeddialogs: libQtGui.so.4 => /fs/Qt_mx28/lib/libQtGui.so.4 (0x1100000) libQtNetwork.so.4 => /fs/Qt_mx28/lib/libQtNetwork.so.4 (0x1e00000) libsocket.so.3 => /dev/shmem/libsocket.so.3 (0x1080000) ldd:FATAL: Could not load library libQtCore.so.4 Is this simply that the 32MByte process space limitation prevents the dlls loading? Thanks.

Hi @all! I was told that I should use Qt on my Beagleboard for a GUI. I also found a doku about changing a Qt Creator project into a QNX project. I still don´t really get this Qt thing, but from what I understood is that I can write the GUI in the Qt Creator and then add it into my Beagleboard BSP. My question would be: How do I have to add the resulting files from Qt into the BSP-package (and especially where?)? I am still new to QNX so the structure and the language I have to use is really hard for me to understand... Also because I don´t know how I have to work with the structure from the BSP (But I think this is a topic for another forum-section :) )

Denis, Thanks for support, but I don't want to dirty this forum up. Could you please also add this comment to other post too. Regards,

Yes. 4.7.1 or 4.8.* will work with current released io-display. There are many hints on this forum, but probably the most comprehensive is: http://dl.dropbox.com/u/13676760/qt_debugging_rev2.pdf It contains links to some programs which you can build and run, as well as some preconfigured target images.

So what about previous version? For example : 4.8.1 or others? If there is a way to do my wishes, then could you please tell me how can I run a QT application on a board where QNX is running. Regards, Seyfettin Sunger

You can only use Qt5 with QNX "UI Core" - which is not yet available for 6.5 SP1. While NDK uses a version of Core UI, there have been changes which like make it incompatible with QNX 6.5 SP1 and/or current Qt5.

Dear Denis, I use Windows7 Home Edition. Maybe, you misunderstood me. I want to do below thins; First what kind of environment do I have? . Windows 7 Home Edition . Not installed QT5 (qt-windows-opensource-5.0.1-mingw47_32-x86-offline.exe) . An ARMv7 based board on which QNX 6.5 can run. What I want to do . I heard QT5 has ported to QNX. If not, which version should I use. . Develop a simple qt applications with qmls. . Then cross-compile it on Windows (cmd screen) for ARM7. . Then add the cross-compiled file to the BSP image. . Run it on the board. I hope, I was clear enough what I would like to with QT & QNX. PS: can I use Blackberry Native SDK for above purposes? Thanks for support Denis. Seyfettin Sunger

Hello People, Is there anyone who can help me to do cross-compile for qt QNX on Windows. Why Windows is always problem for me while doing some configuration on it. Please let me know if there is any documantation that I can port my QT application to my ARM board? I am looking forward to your support. Best regards,

You can also obtain Qt under the LGPL license. QNX has been working closely with KDAB and Digia and others to ensure that Qt for QNX is ported and available for our customer base. In terms of "selling" Qt, if you want to purchase Qt commercial licenses, you need to contact Digia. technical support for Qt is provided by KDAB, Digia (for commercial licensees) and of course teh Qt community at large. At this time, we (QNX Software Systems) do not offer direct fee-based support for Qt as we have deemed it better for this to come from expert Qt companies such as KDAB, Digia and others. > > and continue to invest heavily in integrating and optimizing Qt technology > for QNX.

X86 support is firmly part of our roadmap and have been working on accelerated Intel GPU support ... you will this as well in the coming months. The bottom line is that when it comes to Qt support on a realtime OS platform, QNX is absolutely your best option. We have a Qt4.x port, Qt5 port, QtCreator 2.6 port and continue to invest heavily in integrating and optimizing Qt technology for QNX. The only thing we are dealing with at the moment is coordinating availability of the latest Qt releases with the latest technology from QNX.

I just noticed your reference to PPC in your title. If by this you mean "PowerPC", note that QNX is not investing in Qt or any graphics support for PowerPC platforms from a roadmap perspective.

The UI Early Access Program (UI EAP) will provide access to the experimental versions of the QNX's new composition manager, GPU technology and WFD drivers. Access to this will be limited at first until we are ready to expand availability to a broader target audience (hardware platforms, etc). We have made a significant investment in graphics technology so that we can take advantage of some of the GPU acceleration and allow seamless integrated support for multiple UI/graphics technologies (Qt, OpenGL ES, StoryBoard, Elektrobit). The UI EAP will available in Q1 this year (within the next 2 months). if you need to use Qt "now" (in advance of the UI EAP technology availability), then you should use Qt 4.7x or Qt 4.8x which is supported buy the QNX GF framework. KDAB have been our primary partner when it comes to Qt so if you need any specific help with Qt, contact KDAB (www.kdab.com; till@kdab.com).

Hi all, after QT 5 has been released, I tried to build it for QNX 6.5 SP1. I ended with the Info, that I need the new QNX "Screen" Subsystem, used on Blackberry 10. Well, my QSSL representation told me following: - I have to wait for an experimental prerelease of "Screen". - "Screen" will not be released for PPC !?!? Can somebody coment this? Do I only get target support for CPU's, running on Blackberry devices/emulators in the future? Kind Regards Michael

There is since a long time a lot of Qt activity from RIM ... also HTML5 is strong supported by open source solutions. In the moment I don't see any activities from QSS in order to support Qt or first class open source HTML5 solutions. When I follow the Webinars from QSS I see simply warnings against third party software and very old fairy tales about the Linux kernel. I hope the QSS marketing doesn't believe what they are telling ... The next Webinare about automative solutions will argue against "dangerous" open source third party software. How can I belive that QSS will support Qt and HTML5 in the same extent as RIM ?

The BB10 Qt SDK is pre-Qt5. Also, QNX 6.5 does not include the graphics framework (i.e. composition manager) that is used by BB10.

Qt5 does not run on the currently released graphics framework... only Qt4.

Hi all, I am a beginner trying to use QT for QNX development. I downloaded the example and was just trying to build the cEasy project as the document "using momenticcs ide with qt". I installed QT 4.8.3 mingw under Windows 7. However, I encountered the problem at the beginning. My questions are: 1. which version of qt is the doc using? 2. I can't find the mspecs as in the bat file is looking for: "unsupported/qws/qnx-i386-g++". The "qnx-i386-g++" was not in the "unsupported" folder. Is that because of the wrong version of qt? 3. when linking the project, it was looking for "libCore" ..., what I could found is only "libCore4.a" or (lib"Otherlib4".a). I changed the name of the libs but then the link error for "undefined xxx" appeared. Any hint to help me to start? Thank you in advance! Louis

Hi, I'm working qt to qnx porting process. I think this process are accomplished. When i running this command. The output of the commands as in the following. ./helloapp -qws QQnxScreen: Attached to Device, number of displays: 1 QQnxScreen: Attached to Display 0, resolution 720x400, refresh 60 Hz QQnxMouseHandler: Unable to open mouse device (No such file or directory) I first time running qt app on QNX. Do you think the software works? Not: I could not see any gui with LCD tv? Does QNX support for LCD TV? Thanks

As far as i know, i will carry qt-qnx-armv7 directory to under /usr/local directory i copied qt-qnx-armv7 direcory to sd card. But i can not copy . you can look following link for my steps http://www.youtube.com/watch?v=Srl51JfKPaM thanks

You willl have to experiment. I can't know for sure. I told you where I put the font files on my image.

Dennis Kellly 2012-10-07T23:19:39Z Eren Basturk http://community.qnx.com/sf/go/post96096 2012-10-07T23:01:16Z 2012-10-07T23:01:16Z

I don't include font. I used 4.8.2 for create qmake. Also add prefix=/usr/local/qt-arm-v7 paramter when i creating qmake. My fonts file /usr/local/qt-qnx-arm-v7/lib/fonts. You can look image.png how can i include this fonts? I need information like fonts location on beagleboard image

Eren Basturk 2012-10-07T23:01:16Z Dennis Kellly http://community.qnx.com/sf/go/post96095 2012-10-07T21:59:55Z 2012-10-07T21:59:55Z

So did you include the font files? There are about 80 of them in the 4.8 release. My beagle image has them at /usr/local/Trolltech/QtEmbedded-4.8.0-arm/lib/fonts.

Hi Dennis, I used qt plugins path command but error still countinue i took video for my steps. You can look youtube link I'm waiting monday for your answers http://www.youtube.com/watch?v=Cqo5_UEeSGM thanks

You said, You will use start up script ("before you run your program... or put it in a startup script.") i add this code bzh file I didn't put plugins. How can i put plugins to /usr/lib/qt4/plugins? Thanks for help

Eren Basturk 2012-10-06T00:13:53Z Dennis Kellly http://community.qnx.com/sf/go/post96083 2012-10-05T21:51:31Z 2012-10-05T21:51:31Z

So why didn't you use the command I gave you - before running ./helloapp -qws export QT_PLUGIN_PATH=/usr/lib/qt4/plugins ./helloapp -qws Did you put the plugins in /usr/lib/qt4/plugins ?

Dennis Kellly 2012-10-05T21:51:31Z Eren Basturk http://community.qnx.com/sf/go/post96080 2012-10-05T21:18:38Z 2012-10-05T21:18:38Z

Hi Dennis, You said this code export QT_PLUGIN_PATH=/usr/lib/qt4/plugins but I think this command only QT_PLUGIN_PATH=/usr/lib/qt4/plugins not export QT_PLUGIN_PATH=/usr/lib/qt4/plugins for variable You can look youtube link http://www.youtube.com/watch?v=hUW17EV4f8A You can look commans.txt for my steps I'm waiting for your answers

Eren Basturk 2012-10-05T21:18:38Z Eren Basturk http://community.qnx.com/sf/go/post96078 2012-10-05T20:31:48Z 2012-10-05T20:31:48Z

I did these steps qt now, but still i getting error. please if you show it with a picture of these steps will be very good for me

Eren Basturk 2012-10-05T20:31:48Z Dennis Kellly http://community.qnx.com/sf/go/post96076 2012-10-05T20:14:27Z 2012-10-05T20:14:27Z

Just export the variable .. fo get qTstat # export QT_PLUGIN_PATH=/usr/lib/qt4/plugins before you run your program... or put it in a startup script.

Dennis Kellly 2012-10-05T20:14:27Z Eren Basturk http://community.qnx.com/sf/go/post96075 2012-10-05T20:11:50Z 2012-10-05T20:11:50Z

Qt 4.8.2 does not default the plugin path as expected. Edit /bin/qTstat on the SD card and add the following as the first line so plugin for .jpg images can be used: export QT_PLUGIN_PATH=/usr/lib/qt4/plugins

Dennis Kellly 2012-10-05T19:54:23Z Eren Basturk http://community.qnx.com/sf/go/post96072 2012-10-05T19:52:04Z 2012-10-05T19:52:04Z

Hi Dennis, I thanks for help. I solved this problem with your support but i have a new problem. You can look image.png for my steps. I'm will working weekend for qt porting problem.

You are using beagle board without a network. The error is a Qt library trying to find a socket. I suppose you can start io-pkt-v4 without a driver, and the library will be happy. You'll have to try it.

Dear All, Could you please share some information if it is possible to port 3D QT applications to QNX? Do we need to add extra libraries while building host and target environment to run 3D applications? All replies will be highly appreciated. Regards,

Hi , I'm working qnx one BeagleBoard. I have a error whey i running qt application. My Error: # ./helloapp -qws QWSServerSocket::init: Address family not supported by protocol family QWSServerSocket: unable to create socket.

I wrote previous command incorrectly the command must be as follows "devb-ram ram capacity=16384 &"

Hi Dennis, As far as I understand, we have created 8 Mb ramdisk this command "devb-ram ram capacity=8192 & " but my application 11,3MB. İf I created 16MB ramdisk this command ""devb-ram ram capacity=8192 & " mDoes any problem occurs for qnx target system?

Yes, in a script you need waitfor. When creating by hand from a shell you can't use waitfor as you noted previously.

Dennis Kellly 2012-10-03T13:15:24Z Eren Basturk http://community.qnx.com/sf/go/post95993 2012-10-03T12:47:29Z 2012-10-03T12:47:29Z

Hi Dennis, I created ramdisk. Looks like you forgot "waitfor" command. I added waitfor commands and i have created ramdsik. devb-ram ram capacity=8192 & waitfor /dev/hd1 dinit -hq /dev/hd1t77 mount /dev/hd1t77 /ramdisk export TMPDIR=/ramdisk Thanks for help

Hi Dennis, thanks for answers but I could not find fs-qnx4.so in shared library. ı searched this library on google but i found only one page http://www.qnx.com/developers/docs/6.3.2/neutrino/utilities/f/fs-qnx4.so.html. Where can I find the library?

Eren Basturk 2012-10-01T20:25:51Z Dennis Kellly http://community.qnx.com/sf/go/post95945 2012-10-01T12:28:27Z 2012-10-01T12:28:27Z

'pthread' is a Linux library. My guess is either you didn't build cEasy for QNX - or you are picking it up from the wrong place.

Dennis Kellly 2012-10-01T12:28:27Z Remco Pot http://community.qnx.com/sf/go/post95944 2012-10-01T12:22:02Z 2012-10-01T12:22:02Z

I'm also busy with your demo application cEasy, in Qtcreator on desktop it works very well. Now I'm trying to run it on a virtual machine which is running QNX. qmake_qnx is working fine and give me the objects files. When I run make after the qmake_qnx command I get an error, it says that it can not find the -lpthread,, but if I look in my lib folder there is no such lib as lpthread in it... maybe someone can help me solving my problem. Thanks in advance, Remco

>>>You will need to create a true ramdisk and tell Qt runtime where it is... >>>export TMPDIR=/ramdisk The error you just showed is why you have to create a ramdisk on the target! Run the following commands... since the SD cards is /dev/hd0, the ramdisk should show up as /dev/hd1. devb-ram ram capacity=8192 & dinit -hq /dev/hd1t77 mount /dev/hd1t77 /ramdisk export TMPDIR=/ramdisk Note you will need executables devb-ram and dinit on your target (plus library fs-qnx4.so)

Dennis, i copied hello world app to /tmp directory but I got a new error when running the application. You can look youtube link for error http://www.youtube.com/watch?v=PuGq8U1f-yU also i saw beagle image but i have a beagleboard rev c4 not xM. i tried qt target navigator but there are no built-in ethernet port on the BeagleBoard. I used cisco ethernet to usb converter but I learned that qnx only support axis communication ethernet to usb device thanks for answers

Eren- /dev/hd0t11 is a "raw" device. You have to mount it before you can see your files. # mount -t dos /dev/hd0t11 /fs/dos # cp /fs/dos/helloapp /tmp Have you considered using this demo image for beagle ... rather than a very minimal bsp build? https://dl.dropbox.com/u/13676760/qnx_bglxm.zip (document https://dl.dropbox.com/u/13676760/qnx_bglxm.pdf) When this image boots, it automatically mounts the SD card as "/" - so "ls /" will show your helloapp file. Additionally, this image sets up the network - so you can "paste" your file directly to the target using Mometics "target filesystem navigator". The demo image is all setup to run Qt apps - in fact, several are installed on that image. Dennis

"waitfor" is used in boot scripts. If you run the commands from a shell you would omit it.

/tmp is normally linked to /dev/shmem which (as you see) does not support creation of directories. One soluitiion is to create a ram drive and mount that it at /tmp devb-ram ram capacity=8192 & waitfor /dev/hd1 dinit -hq /dev/hd1t77 mount /dev/hd1t77 /tmp Note "hd1" may differ but likely "hd0" is mmcsd.

Serveral things... 1) Looks like I forgot "export" in my post you referred to... LD_LIBRARY_PATH=$LD_LIBRARY_PATH:<wherever the libraries are located> should be export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:<wherever the libraries are located> ... just like the other variables! 2) You cannot execute from the SD card because the bsp did not start the driver with the right permissions: It should look like: devb-mmcsd-beagle cam quiet blk cache=2m dos exe=all mmcsd noac12 It is the "dos exe=all" that is missing - chmod won't work! 3) If you hadn't mounted your card at /tmp, you could have copied 'helloworld' to /tmp and then done chmod and successfully run it. Probably should mount at /dos or something like that. BTW you can create macro's in u-boot - you don't have to enter all that stuff by hand everytime :)

Hi Dennis, I changed computer at the office. I wrote the previous message Let me tell you the problem. I have two different problem. I'm getting this problem when I'm super-user : ntoarmv7-g++: error trying to exec 'cc1plus': execvp: No such file or directory I'm getting this problem when I'm normal-user : ntoarmv7-g++: error: environment variables QNX_HOST and QNX_TARGET not defined What can I do about it? Thanks for help

I assume you are building for Qt4... image5.png says "ARM version 1". It is unclear to me whether you are building for "armle-v7". Only libraries for armle-v7 are available - unless you build them yourself. BUT you should run 'v7' on beagle. To be sure what libraries need to be included, run this against the program you built. # ntoarmv7-objdump -x helloworld | grep NEEDED You should see output indicating which shared libraries it is linked to.

Ok, here is the answer. You need to add follow macro definitions to $CFLAGS and $CXXFLAGS: CXXFLAGS="-D_XOPEN_SOURCE=600 -std=gnu++0x" CFLAGS="-D_XOPEN_SOURCE=600 -std=gnu99" Explanation from Suzuki Toshiya (poppler@lists.freedesktop.org): «Just I've checked that current main trunk of poppler can be built with Blackberry Playbook NDK (QNX 6.5.0), with following flags to use POSIX environment in QNX: CXXFLAGS="-D_XOPEN_SOURCE=600 -std=gnu++0x" CFLAGS="-D_XOPEN_SOURCE=600 -std=gnu99" The background of the flags are following: -D_XOPEN_SOURCE=600 * to enable getpwnam() etc, just -D_POSIX_SOURCE is sufficient. * to enable strtok_r(), -D_POSIX_C_SOURCE=199506 or newer is sufficient. * to enable mkstemp(), -D_XOPEN_SOURCE=600 is needed. -std=gnu++0x and -std=gnu99 * isfinite() is defined in GNU C, C99, and POSIX 2004. QNX 6.5.0's header file covers POSIX 1998-2001, but not 2004, so "-std=gnu++0x" (for CXXFLAGS) or "-std=gnu99" are required. Regards, mpsuzuki»

I need a pdf support with Qt 4.7.1 in my QNX 6.5.0, installed to VMWare Workstation. I try to build poppler ver.0.20.3 (poppler.freedesktop.org) in next few steps (GCC 4.4.2.): 0) Configure, build and install all dependencies of poppler (Fontconfig-2.10.1, Cairo-1.12.2, libjpeg-8d and libpng-1.5.12). 1) Set proper environment variables to build poppler: #!/bin/sh export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig export CFLAGS="-I/usr/local/include/pixman-1 -I/usr/include/qt4 -I/usr/pkg/include" export LDFLAGS="-L/usr/local/lib -L/x86/usr/lib -L/usr/lib -L/usr/pkg/lib" export LIBS="-lpixman-1 -lQtGui -lQtCore -lQtNetwork -lopenjpeg" export CXXFLAGS=${CFLAGS} export FREETYPE_CFLAGS=-I/usr/local/include/freetype2 export FREETYPE_LIBS="-L/usr/local/lib -lfreetype" export FONTCONFIG_CFLAGS=-I/usr/local/include/fontconfig export FONTCONFIG_LIBS="-L/usr/local/lib -lfontconfig" export CAIRO_CFLAGS=-I/usr/local/include/cairo export CAIRO_LIBS="-L/usr/local/lib -lcairo" 2) Unpack and configure it (see log file in the attachment): # ./configure --disable-jpeg 3) When I try to build poppler it fails with error in goo/gfile.cc: # make make all-recursive make[1]: Entering directory `/home/ftp/poppler-0.20.3' Making all in goo make[2]: Entering directory `/home/ftp/poppler-0.20.3/goo' CXX gfile.lo gfile.cc: In function 'GooString* getHomeDir()': gfile.cc:99: error: 'getuid' was not declared in this scope gfile.cc: In function 'GooString* getCurrentDir()': gfile.cc:121: error: 'getcwd' was not declared in this scope gfile.cc: In function 'GooString* makePathAbsolute(GooString*)': gfile.cc:437: error: 'getcwd' was not declared in this scope gfile.cc: In function 'std::time_t getModTime(char*)': gfile.cc:455: error: no matching function for call to 'stat::stat(char*&, stat*)' /usr/qnx650/target/qnx6/usr/include/sys/stat.h:133: note: candidates are: stat::stat() /usr/qnx650/target/qnx6/usr/include/sys/stat.h:133: note: stat::stat(const stat&) gfile.cc: In function 'GBool openTempFile(GooString**, std::FILE**, const char*)': gfile.cc:531: error: 'mkstemp' was not declared in this scope gfile.cc: In constructor 'GDirEntry::GDirEntry(char*, char*, GBool)': gfile.cc:715: error: no matching function for call to 'stat::stat(char*, stat*)' /usr/qnx650/target/qnx6/usr/include/sys/stat.h:133: note: candidates are: stat::stat() /usr/qnx650/target/qnx6/usr/include/sys/stat.h:133: note: stat::stat(const stat&) make[2]: *** [gfile.lo] Error 1 make[2]: Leaving directory `/home/ftp/poppler-0.20.3/goo' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/home/ftp/poppler-0.20.3' make: *** [all] Error 2 - Functions getuid(), getcwd() and getcwd() are in my <pwd.h> file, but their declarations are covered by macros: #ifdef __EXT_POSIX1_198808 /* declarations */ #endif Error with stat::stat(char*&, stat*) because g++ trying to call struct constructor instead of call function stat(char*&, stat*), that declared in <sys/stat.h>. Declaration of mkstemp() in <stdlib.h> is macro protected too: #if defined(__EXT_XOPEN_EX) /* declarations */ #endif I tried to build poppler in Win7 (msys+MinGW) and everything was ok, it's works. Poppler binaries for pkgsrc from ftp.netbsd.org are without \Splash\ support, but I need this backend. Define macros manually in $CFLAGS ("... -D__EXT_XOPEN_EX -D__EXT_POSIX1_198808") did not solve my problem. - So, my questions: 1) What is the correct way to set POSIX version in headers? 2) Why stat() function can't be called? 3) What I need to do to define __EXT_XOPEN_EX macro? Thanks.

Hi, I wanted to post a quick update regarding the status of Qt on QNX. Generally speaking, almost all of our Qt efforts are focused on Qt5 for QNX. Although the Qt5 official release date is still a few months away, we have been working closely with KDAB to upstream QNX changes so that when Qt5 is officially released, you see QNX target support right out of the box. In the meantime, check out http://qt-project.org/ for the latest. Thanks Grant

I have posted a second web application utilizing HTML5's WebSocket. This application is a replacement for the Photon desktop "System Monitor", showing CPU, memory, disk, and net utilization in pseudo-realtime. The monitor runs in the "webvu" Qt application - as well as in a desktop or tablet browser, making it suitable for headless systems. The application tutorial and archive are here: http://dl.dropbox.com/u/13676760/webStats.pdf A Momentics IDE workspace is here: http://dl.dropbox.com/u/13676760/machStats_ide.zip The app ("machStats") is pre-configured into the i.mx53 and Beagle xM demo images.

In the Qt public repository. QNX follows the "embedded Linux" model... and that model has no openGL support. I built from repository a couple of weeks ago, and no "GL" libraries were built. This changes with 5.x - I assume - because I have a KDAB Qt5 demo showing openGL running on Playbook. But note that from 4.8 to 5.x, the QNX graphics model changes and you need a "next gen" graphics subsystem - not publicly available yet.

That is correct. You have to manually "fix" them by making copies of the linked file. Certain tools will do that for you - I believe if you use '7-zip' to untar the file, the links will correctly become copies.

Thanks. The TAR file has symbolic links and when they were extracted under windows, the links were lost and zero length files were created.

Interesting, "/usr/photon/bin/devi-hid -Pr kbd mouse &" did work for me from telnet. (You do have to start the Qt app after you start devi-hid or it won't work...) For me devi-hid is started in the bootscript - that works too. Anyway, glad you got everything working!

You have to manually start the following as on p7. /usr/photon/bin/devi-hid -Pr kbd mouse When you run "ph" to start photon, devi-hid is started automatically (in a different mode). For Qt, you must start it yourself.

Well the linker is complaing that you have invalid binaries. "C:/QNX650/target/qnx6/armle-v7/usr/lib/libQtGui.so: file format not recognized; treating as linker script My guess is perhaps that is a zero-length file. There are likely three files wit the QtGui name and only one has content. Copy the content to libQtGui.so. Repeat for all libQt*. Then it should build.

I did not build x86 with the "latest", so I did a fresh "git". I got the same error you found. Seems unnecessary to build "x11" for x86 "embedded" but it does...

I have posted a web application - utilizing HTML5's WebSocket - which runs in the "webvu" Qt application presented previously. WebSocket allows a “persistent connection” between target and browser so there is no polling. Both the host and the target may transmit data on an open socket with little latency - perfect for control appliications. The app ("webEasy") is pre-configured into the i.mx53 and Beagle xM demo images. SInce it is a web app, it can be viewed both on the target display via webvu, AND via external browsers including: • desktop versions of Chrome, Safari and Firefox • Blackberry BB7 (9900) smartphones • Android smartphones (only very recent software – Ice Cream Sandwich?) • Playbook (v2.x) The key part of the solution is a webserver named "websock5" which is written in C. Included with the tutorial is an IDE workspace archive for websock5 which allows you adapt the server to any client Javascript you may write. The application tutorial and archive are here: http://dl.dropbox.com/u/13676760/qtHtml5.pdf. http://dl.dropbox.com/u/13676760/websock5_ide.zip You can try webEasy by downloading the SDcard image which matches your target: For i.mx53 QSB with VGA output: http://dl.dropbox.com/u/13676760/qnx_mx53.zip http://dl.dropbox.com/u/13676760/qnx_mx53.pdf For i.mx53 QSB with 4.3" LCD/touch panel: http://dl.dropbox.com/u/13676760/qnx_mx53_lcd.zip http://dl.dropbox.com/u/13676760/qnx_mx53_lcd.pdf For i.mx53 Beagleboard xM with hdmi output: http://dl.dropbox.com/u/13676760/ qnx_bglxm.zip http://dl.dropbox.com/u/13676760/ qnx_bglxm.pdf

Hiya, I'm trying to do some dev for the playbook using ndk 2.0.1 that rim released awhile ago. It provides libstdc++ along with gcc 4.4.2 based tools. I'm also using qt for my application. The problem I'm having is that qt and libstdc++ seem to work fine independently, but when I link to both of them in the same application, I get a segmentation fault. Note that I don't need to actually use any Qt code, just linking it in is enough to cause a crash. Here's a sample application: #include <iostream> #include <sstream> int main(int argc, char *argv[]) { std::cout << "This doesn't work\n"; return 0; // i think it crashes here when the os tries to do cleanup } Here's the stack trace from the crash: #0 0xb8b5e329 in __gnu_cxx::__exchange_and_add (__mem=0x0, __val=-1) at atomicity.cc:36 36 atomicity.cc: No such file or directory. in atomicity.cc (gdb) backtrace #0 0xb8b5e329 in __gnu_cxx::__exchange_and_add (__mem=0x0, __val=-1) at atomicity.cc:36 #1 0xb8b03471 in __exchange_and_add_dispatch (__val=<optimized out>, __mem=<optimized out>) at /home/builder/hudson/650-gcc-4.4/svn/linux-x86-o-ntox86/i486-pc-nto-qnx6.5.0/pic/libstdc++-v3/include/ext/atomicity.h:79 #2 _M_remove_reference (this=<optimized out>) at /home/builder/hudson/650-gcc-4.4/svn/linux-x86-o-ntox86/i486-pc-nto-qnx6.5.0/pic/libstdc++-v3/include/bits/locale_classes.h:505 #3 std::locale::~locale (this=0xb837d5fc, __in_chrg=<optimized out>) at ../../../../../libstdc++-v3/src/locale.cc:89 #4 0xb8b0faa9 in ~basic_streambuf (this=<optimized out>, __in_chrg=<optimized out>) at /home/builder/hudson/650-gcc-4.4/svn/linux-x86-o-ntox86/i486-pc-nto-qnx6.5.0/pic/libstdc++-v3/include/streambuf:193 #5 std::basic_filebuf<char, std::char_traits<char> >::~basic_filebuf ( this=0xb837d5e0, __in_chrg=<optimized out>) at /home/builder/hudson/650-gcc-4.4/svn/linux-x86-o-ntox86/i486-pc-nto-qnx6.5.0/pic/libstdc++-v3/include/fstream:215 #6 0xb0bbd205 in __cxa_finalize () from /home/preet/bbndk-2.0.1/target/qnx6/x86/lib/libc.so.3 #7 0xb832de67 in _btext () from /home/preet/bbndk-2.0.1/target/qnx6/x86/lib/libcpp.so.4 #8 0xb836a265 in _fini () from /home/preet/bbndk-2.0.1/target/qnx6/x86/lib/libcpp.so.4 #9 0xb0bd46d3 in ??

Qt has a rule that events can obly be sent to objects in the current thread, i.e. sending events directly accross threads, using QCoreApplication::sendEvent() is forbidden. The easiest way to solve your problem is to use QCoreApplication::postEvent() (or QApplication, in your case). Unlike QCoreApplication::sendEvent(), QCoreApplication::postEvent() will push the event to the receiver thread's event equeue, and the event will be processed only when the control returns to the receiver's thread main loop. This ensures that the event will be processed on the context of the receiver's thread, which is the behavior you are expecting. Please note that the event must be allocated on the heap, since the post event queue will take ownership of the event and delete it once it has been posted. In practice, your code should look like: void QNX_thread_function( void *pvParameters ) { // Code that executes when a can message is received QEvent *event = new QEvent(static_cast<QEvent::Type>(QEvent::UserType + 1)); QApplication::postEvent(myqtclass, event); } However, if all you would like to do is signalizing your Qt class that a CAN message has arrived, you can instead take advantage of the Qt MetaObject system instead of reimplementing QObject::event(). class myqtclass : public QObject { Q_OBJECT public: /* ... */ Q_INVOKABLE void canMessageArrived(); }; and then: void QNX_thread_function( void *pvParameters ) { // Code that executs when a can message is received QMetaObject::invokeMethod(myqtclass, "canMessageArrived", Qt::QueuedConnection); } In a nutshell, the Q_INVOKABLE macro tells the Qt MetaObject system that canMessageArrived can be invoked using QMetaObject::invokeMethod - it is a bit more complicated than that under the hood, but let's leave it like this for the sake of simplicity. The caveat then is passing Qt::QueuedConnection to QMetaObject::invokeMethod. This means that, instead of invoking the method directly (akin to QApplication::sendEvent()), the method is invoked when control returns to the event loop of the receiver's thread and is executed in the context of the receiver's thread (akin to QApplication::postEvent()). You can also use Qt::BlockingQueuedConnection - the difference is that, while QMetaObject::invokeMethod() will return immediately with the former, when using the latter it will only return after the method has been executed.

Yes, I realize you are not using QML... why, I don't know since that is the current Qt-preferred method. Still, from what I have read, signals and slots existed prior to QML. So you need to find such an example. Some of the signal/slot packaging of qTstat will likely still apply.

Hello, I have looked into the example. I don’t have a qml application, instead I have written all QT sw with objects. In the example the thread calls valuesChanged, which is a signal that I guess is linked into the qml code as onValuesChanged. How do I do if I don’t have qml and want this “onValueChanged” to be a function in the class instead? /Magnus

Magnus- This example has a thread which "signals" back to the UI... http://community.qnx.com/sf/discussion/do/listPosts/projects.qt/discussion.general.topc20365 Note that the thread is created as a Qt object (not pthread_create) but thread execution is the same. Here the thread is waiting to be notified by pps, but it could be waiting for a CAN message. If you don't want your CAN logic in a Qt thread, you could wait for a pulse in the Qt thread, and send the pulse from a standard (non-Qt) C program with CAN knowledge. This way, you can easier debug the more complex non-Qt portion, and your UI remains simple.

Hello, I have a 'AM335x EVM board' and have downloaded the BSP “Texas Instruments AM335x EVM” project. I use QNX 6.5.0 and Momentics 4.7.0. I have an issue that I don’t know how to call event/message functions inside the “QT thread” from a QNX thread in my QNX application. In main I create a thread for receiving can messages. When I have received a can message I would like to send an event/message/signal to my “myqtclass” event function or another function inside the object. I end up in the function myqtcalss::event but I still execute in the “qnx function thread” not the “QT thread”. Because of this I receive an error message from QT. I would like to send an event/message/signal so the “QT thread” execute it. Do you have any suggestion how to do this? Example code: ********************* main.c MyQTClass *myqtcalss; int main(int argc, char **argv) { // Creating QNX can receive function thread … QApplication app(argc, argv); // QT code … myqtcalss = new MyQTClass; … return app.exec(); } ********************* myclass.cpp bool myqtcalss::event(QEvent *event) { // Here I would like to end up in the “QT thread” } ********************* qnx.c void QNX_thread_function( void *pvParameters ) { // Code that executes when a can message is received QEvent event((QEvent::Type)1001); QApplication::sendEvent(myqtclass, &event); } *********************

thank you ,i can do that successfully ,the problem has bothered me for a whole week,you give me a lot of help. and i still have a question,i know that qt can be intergrated with eclipse which makes the developer convenient,however, can it be intergrated into the momentics (run and debug in the momentics environment)? for me ,the development process seems that ,first i create and debugmy project in the qt sdk for windows , to make it run correctly ,next,i make it a qnx program by qmake_qnx?

Yes, now I see where that line is coming from :) I assume you cut_and_paste qmake_qnx.bat from the pdf and maybe this is causing the problem. File qmake_qnx.bat in this archive.

hello ,i'm new to qt/qnx,now i encounter a question ,that is how i run my own qt app on the target based on qnx (my host is winxp,and target is vmware).i don't really know how it works, i guess: 1)the first step : i make a project by qt-creator and run ,debug to make sure it will run well. 2)the second step : i make the resource that is needed to run on qnx again . According to this thought,i did the following things: 1)first i create a project "hello world" in the qt-creator ,and it works well 2) as the "read me"says,i enter C:\Qt\hello,and create a makefile including "LIST=OS CPU VARIANT MAKEFILE=GNUmakefile include recurse.mk ##eof" 3)Inside the same directory, create subdirectories called nto-x86-o,including "GNUmakefile" ifndef QCONFIG QCONFIG=qconfig.mk endif include $(QCONFIG) include $(MKFILES_ROOT)/qmake-qt.mk ##eof 4)from cmd prompt,i enter the C:\Qt\hello,and run "make" ,but it shows mingw32-make is Not internal or external command, also not be operation of the procedure or a batch file. 5)so i enter"ksh",run "make",it shows errors as the attachment shows ,but it produce a .project and a hello file.so i transfer the hello file to the vmware ,the app absolutely failes to run . another question ,i know that qt can be intergrated with eclipse which makes the developer convenient,however, can it be intergrated into the momentics (run and debug in the momentics environment)? thank you ,and I look forward to your reply

I know you guys know this already but Qt 4.81 is released and has a QNX port. Qt 5.x (pre-release) is also available and has QNX integration with the new graphics framework that will be made available in late June / July. We are not posting either of these here as we want everyone to get them from the master qt repository.

At the beginning, I didn't noticed Trolltech.conf file. Now both 4.7 and 4.8 can decode JPG pictures. The mistake I made before is that I didn't replace image plugin 4.8 with 4.7 when I run 4.7, causing the jpeg failed in 4.7. In addition, the new libqmlwebkitplugin.so you gave me might be the 4.7 edition, 'cause I noticed in my Trolltech.conf that QtWebKit\libqmlwebkitplugin.so=40701, 0, armv6 qws/qnx g++-4 full-config, 2011-02-25......... So, when I run web function, it shows an error concerning the build key. I wonder if you could send me a new one. BTW, do you know something about International character support for Qt applications say Chinese or Japanese characters? I am really gratitude for your help. Many thanks

>>>That's interesting. Because when I use 4.8 component, the JPEG picture is loaded correctly. >>>The .jpg file in my apps can't be rendered either. Huh? >>>Could you give me your 4.7 components? qt_qnx_2011-02-24b.zip from http://community.qnx.com/sf/frs/do/viewRelease/projects.qt/frs.binpkg.targets One thing, to run jpegs, the file "Trolltech.conf" must be correct. This file is created on app startup if it does not exist. This file is created in $HOME/Settings. If on your target, that location is not writeable, I am guessing plugin's won't work. For an embedded system $HOME may be '/'. Is that writable on your target? Try deleting it and see if it is recreated. Of course, plugin libraries must be present in /usr/lib/qt4/plugins/imageformats as well. Remember that .PNG images are handled without a plugin, so this can cause confusion.

I assume since your dns is not working, you are using a static IP address... otherwise dhcp would have provided the gateway and dns server. To setup dns for static ip... Be sure to specify netmask on your ifconfig line as... ifconfig fec0 10.0.2.201/24 Set gateway... route add default 10.0.2.1 Setup dns (client) edit/create /etc/resolv.conf to contain domain foobar nameserver 8.8.8.8 Test by ping'ing by name. Once that works, the webkit plugin will resolve names. Note 8.8.8.8 is a free google dns server - easy to remember! I have succeeded in getting jpeg's from web to decode using the 4.7 components for x86 and armle-v7. (So far, I have not gotten them to work using 4.8 components.)

Dennis Kellly 2012-04-22T13:15:01Z David Yang http://community.qnx.com/sf/go/post92687 2012-04-22T10:00:57Z 2012-04-22T10:00:57Z

In fact, I can ping and load www.google.com by its IP address, say 74.125.71.99. But when I ping www.google.com or type http://www.google.com in the URL input box, the page can't be loaded. It seems the domain name resolution has a problem. I can't make sure the source of the problem lies in io-pkt v4 or elsewhere. Do you have any idea? BTW, the JPG picture still can't be loaded properly in 4.7 runtime components even if I have exported Qt_Plugin ENVIRONMENT VAR. There are also lot of square boxes instead of characters, do I have to add more font in the font directory?

For a QML version, you should copy the QtWebKit/libqmlwebkitplugin.so and QtWebKit/qmldir to your application directory, and the Qtwebkit module uninstalled line can be passed. For my QML version browser, I can load a local webpage. But when I load an Http webpage, for example http://www.google.com, it failed.But, I can ping www.google.com in my target, which might means that my Internet connection is rightly configured. You have mentioned that you can load a URL page. What kind of net-related service should I start before starting the Browser?

>>>I have no source file and I can't solve this problem. The same source is available to anyone. See http://community.qnx.com/sf/discussion/do/listPosts/projects.qt/discussion.general.topc21351 I have been struggling with the webkit plugin as well. If I build a non-QML UI with a webView, I can display a page (local or via socket) - BUT the image plugins (.jpg etc) just don't work. (This is on a system where jpeg's are properly displayed QML scripts.) If I build a QML version, I can't get past the line "import QtWebKit 1.0" - get "module "QtWebKit" is not installed".

Dennis Kellly 2012-04-20T14:23:08Z David Yang http://community.qnx.com/sf/go/post92655 2012-04-20T03:01:01Z 2012-04-20T03:01:01Z

I have tried the new .so, the problem still exists. When I revert to the 4.7 .so, the browser seems to work, but the UI runs very slowly and jpg decoding doesn't work. I really hope to use the 4.8 shared object. I wonder if the libqmlwebkitplugin.so is built with the right build key since the error message is: The plugin '/fs/MMI/QtWebKit /libqmlwebkitplugin.so' uses incompatible Qt library. Expected build key "arm qws/qnx g++-4 no-pkg-config", got "armv6 qws/qnx g++-4 full-config" I wonder if the libqmlwebkitplugin.so is built by you from source. I have no source file and I can't solve this problem. I have downloaded QtWebKit 2.2 source from its Website. But I have no idea how to compile the webkit plugin as a QNX .so file, I have no tool.

>>>would it be possible that I get a 4.8 lib? I have packaged the armv7 version ofs libQtWebKit.so.4.9.0 and libqmlwebkitplugin.so in the following archive: http://dl.dropbox.com/u/13676760/armv7-runtime2-4.8.0.zip Note that libQtWebKit.so that is built from the repository identifies itself as "4.9.0" rather than "4.8.0" as the rest of the libraries. You can try to rename it as libQtWebKit.so.4 if necessary. Hope this helps.

The file libqmlwebkitplugin.so is from the qt_qnx_2011-02-24b.zip package. It is a Qt4.7 patch, on the other hand, the Qtlib I used in my target is from armv7-runtime-4.8.0.zip Is this the reason that causes Qtlib incompatible issue? I have to revert to 4.7lib or would it be possible that I get a 4.8 lib?

Hi, Dennis I am debugging a Qt application and I have met with a problem which might concerns the compile process of my application. The error message is like the following: file:///fs/MMI/qml/Browser/BrowserView.qml:37:1: plugin cannot be loaded for module "QtWebK it": The plugin '/fs/MMI/QtWebKit/libqmlwebkitplugin.so' uses incompatible Qt library. Expected build key "arm qws/qnx g++-4 no-pkg-config", got "armv6 qws/qnx g++-4 full-config" What kind of change should I make to make the build key as expected? Thanks

Qt4.7 or 4.8. I have a demo of QTOpenGL accelerated on the BB Playbook with QT5. It is extremely fast - but it uses a different graphics framework (from the one in 6.5) to support accelerated openGL.

Hi All, As far as I know, QNX doesn't support Open GL, but I am not sure if Open GL applications can run via QT on QNX? Do you have any comment about this? In QT project, Is QTOpenGL module ported on QNX? Looking forward to your comments. Best regards,

This problem has already been solved by myself by creating a symbolic link. The Qt4.8 .so runs well. Thank you all the same, Dennis.

One more question: I have created a Hello World app in Qt QuickUI and compiled it. When I run it, I found that it requires the directory QFontDatabase: /usr/photon/font_repository. Can I redirect it to other path by setting ENVIRONMENT VAR? Because my photon directory has been shifted to my SD card. Including them in image will lead to a very large image. BTW it shows a message like following: file:///fs/NewQt/qml/NewQt/main.qml:2:1: module "QtQuick" version 1.1 is not installed import QtQuick 1.1 ^ I opened your armv7-runtime-4.8.0 package, and I saw a Trolltech directory which contains a lot of font, how to use them?

Hi, Dennis: Do you have any idea about egalax touch controller? I can't make it work properly. I start the device by the following command: io-hid -d egalax devi-hid -Pr touch With the QNX system driver devh-egalax, the X-Y axis are reversed and the touch point is not precise. Configuring calib file seems useless, or I don't know how to configure calib file properly. The driver shipped with the touchscreen is a RS232 serial driver which may not work for a USB touch controller interface. On the other hand, the QNX car application runs very well on this touchscreen, I wonder is there any way to let egalax touch controller works properly?

David Yang 2012-04-15T15:30:46Z Dennis Kellly http://community.qnx.com/sf/go/post92549 2012-04-13T16:05:00Z 2012-04-13T16:05:00Z

Touchscreen is fully supported for Qt on the i.mx53 qsb w/lcd image posted on this forum. You must have a driver loaded to use touch. For example for an hid-compliant usb touchscreen... io-hid -d usb devi-hid -Pr touch For Qt, you would change the QWS_MOUSE_PROTO line to something like... export QWS_MOUSE_PROTO=qnx:/dev/devi/touch0

Hi,Dennis Very happy that the application is running on Beagle board. I have connected mouse and keyboard and it works well. BTW, I wonder if touchscreen control is possible for the Qt application?

Hi,Dennis: Thank you for your support. The Qt UI runs partly. It shows the following message： # /fs/speedo/speedo -qws Debug: QQnxScreen: Attached to Device, number of displays: 1 Debug: QQnxScreen: Attached to Display 0, resolution 720x400, refresh 60 Hz Critical: QQnxMouseHandler: Unable to open mouse device (No such file or directory) Critical: QWSQnxKeyboardHandler: Unable to open device (No such file or directory) Warning: file:content/speedo.qml: File not found Debug: program starting I have already put the content file in the sd card, but it can't recognize it. Do I have to set other environment variables? Thank you very much.

Sounds like it wants a network to be started. I guess I never built a runtime without a network present. Try starting io-pkt-v4. On 3530 beagle, no interface is present, but maybe it will allow Qt to start.

Hi, Dennis, You mean I have to create another QNX4 file system on my SD card? I have already built a FAT32 system on my SD card by the following command in buildfile: devb-mmcsd-beagle dos exe=all lfn=show sfn=windows & waitfor /dev/hd0 5 & mount -t dos /dev/hd0t12 /fs I can't create a qnx4 filesystem by using fdisk since the SD card is already occupied by FAT32 filesystem. How can I mount a qnx4 filesystem on the SD card? In RAM?

The solution is in this post: http://community.qnx.com/sf/discussion/do/listPosts/projects.qt/discussion.general.topc20245 Basically you need to create a qnx4fs ramdisk mounted at /fs/ram and export TMPDIR=/fs/ram

Absolutely! That is in the documentation for the examples.

>>> (2.01a) (Qt 4.8.0) The second version number is the version of the .so liibraries it expects to link to at runtime.

Dennis Kellly 2012-03-28T11:08:52Z Dennis Kellly http://community.qnx.com/sf/go/post92312 2012-03-28T11:06:38Z 2012-03-28T11:06:38Z

The binary is indeed the same. The QML seems not to be processed in anyway during the build. In fact, "content" (the arbitrary subdir location for this example) does not appear in the .pro file! But it IS specified in the C++ sources... File mainwidget.h: const QString contentPath = "content/"; File mainwidget.cpp: QString filename(contentPath + "easyQML.qml"); The content folder is used at RUNTIME since the "MainWidget" is subclassed to a QtDeclarativeView. This view (also referred to as "Qt Quick") starts a runtime object which reads and displays the QML content/easyQML.qml - almost like a browser starts index.html. Since the QML specifies "Connections", a runtime linkage is established with the target instance "easyData" (in C++). This linkage allows easyData to "emit" a signal recognized by QML and for QML to call a "slot" in easyData. Note, if no "Connection" is specified, the QML willl still load and function - i.e. you can make a QML-only Qt program! (However, for device control this is not very useful.)

By the way,I opened some makefile in your demo and found "Generated by qmake (2.01a) (Qt 4.8.0)", while in my makefile it is "Generated by qmake (2.01a) (Qt 4.7.1)", is there any difference? Do I have to update my qmake tool?

Hi,Dennis Thank you for your quick reply. I have another question. >>>This will give you a dummy QML file - where you put your script, and >>>you can add additional C++ files for your "data" >>>handler (signals and slots). It will not have the "exact" structure of >>>cEasy but should be a valid starting point for a new app. I removed the folder "content" from my project folder, this folder contains .qml file and some images. The build is still successful, the binary is the same. So, what's the function of qml if I can make the project without it?

David Yang 2012-03-28T03:47:40Z Dennis Kellly http://community.qnx.com/sf/go/post92285 2012-03-27T10:55:46Z 2012-03-27T10:55:46Z

>>> What kind of project should I create in QtCreator? With the latest Qt Creator, I would start with QtQuick Project/QtQuick Application... "contains both QML and C++ code and includes a QtDeclarative view." This will give you a dummy QML file - where you put your script, and you can add additional C++ files for your "data" handler (signals and slots). It will not have the "exact" structure of cEasy but should be a valid starting point for a new app. >>>r? By the way if I want to migrate a web browser from Qt platform to QNX, is it possible by your method? This would NOT likely be a Qt Quick project. But QNX qmake should still handle it. Sorry, I have not tested qmqke_qnx.bat with anything but Qi Quick examples. >>>I copied all the .h .cpp and.pro to a folder and the make failed. Don't copy .pro - it needs to be built for qnx via qmake.
