Notes on building Qt 4.8.0 from the Nokia repository   
The following pdf details using a Linux host to build Qt 4.8.0 for QNX from the repository, cross-comple Qt Creator 
applications, and deploy them on a QNX 6.5 embedded target.

Thanks for you tutorial.

Did you tested to build OpenGL module also?

Thanks

I did not test openGL.  Please share your results here if you do!  Thanks.

Re: Notes on building Qt 4.8.0 from the Nokia repository   
In the pdf associated with this thread, I described testing the 4.8.0 libraries on the i.mx53 "VGA" image.  Not only did
 the 4.8.0 libraries work, but intensive graphics used noticeably less CPU.

However, when I deploy the libraries on i.mx53 with LCD and touchscreen, the same applications are not usable.  The 
touchscreen only occasionally recognizes a touch and the CPU is completely consumed.  It seems that some code from the 4
.7.1 source did not get correctly ported to the Qt repository.

Since I have only tested on one "touch" platform, I suppose it could be platform-specfic - but be aware of this possible
 issue.

This app note:

has been updated for Qt repository version 4.8.2, reflecting some changes in the build process.

What is the the URL or the svn command to download Qt 4.8.2 for QNX ?

Re: Notes on building Qt 4.8.0 from the Nokia repository   
Sorry, are you looking for pre-built?

To get source, AFAIK you have to use "git".

# git clone git://gitorious.org/qt/qt.git

Dennis,

sorry I didn't read your build documenation.
I'm just creatung a Linux installation of Momentics ...

Do you know the price (round about?) of a  pre-built version of digia?

Re: Notes on building Qt 4.8.0 from the Nokia repository   
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...

First I ran 
# apt-get install libx11-dev

which installed /usr/lib/X11/Xlib.h .. and I thought everything would work after that.

However, it is still ignoring this file even though it is installed in the standard location...

Re: Notes on building Qt 4.8.0 from the Nokia repository   
Thanks Armin for pointing out the error in the 16-Jul-12 version of the document!

I have made corrections and replaced the online version with a 31-Jul-12 version...

Re: Notes on building Qt 4.8.0 from the Nokia repository   
Dennis,

I have tested qtEasy and ran:

#
#export QWS_DISPLAY=qnx
#export QWS_KEYBOARD=qnx
#export QWS_MOUSE_PROTO=qnx
# cEasy -qws
QQnxScreen: Attached to Device, number of displays: 1
QQnxScreen: Attached to Display 0, resolution 1280x1024, refresh 60 Hz
QQnxMouseHandler: connected.
QWSQnxKeyboardHandler: connected.

The graphics is OK  ... but mouse and keyboard are not working.
Is this the expected result ?

--Armin

PS: ph works if started from the telnet session ...

Re: Notes on building Qt 4.8.0 from the Nokia repository   
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.

Yes ... I did it, but within the telnet session --> but no success.

When I run  "/usr/photon/bin/devi-hid -Pr kbd mouse &" locally on the QNX 6.5 machine ALL is working!
That means  ALL in demos and examples :)

Thanks

Re: Notes on building Qt 4.8.0 from the Nokia repository   
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!

Yes ... it works also for me. I started devi-hid as a "normal deamon" 
process and not as a background process :)
