Qt Target Library Location?   
Hi,

I'm working qt to qnx porting process. I've completed operations on the host side.
I can complie qt application for qnx armv7 version. 

I need some information on the target side process.

I carry him where qt target libaries?

Do I carry him sd card or after create a partition image file created by section carry him?

Thanks for Help

OK ...  but  both hardware systems are ARM based and running more or 
less compatible version of QNX6.x ...

Re: Qt Target Library Location?   
>>>I carry him where qt target libaries?
Actually, they can be anywhere specified by environment variable LD_LIBRARY_PATH, but the "standard" location would be /
usr/lib

>>>Do I carry him sd card or after create a partition image file created by section carry him?
You can only put them on the SD card if you mount it before you try to use the libraries.  If you don't know how to 
mount the SD card, then you must put libraries in the IFS !

The folliowing assumes Qt4...

LD_LIBRARY_PATH=$LD_LIBRARY_PATH:<wherever the libraries are located>

export QWS_DISPLAY=qnx
export QWS_KEYBOARD=qnx
export QWS_MOUSE_PROTO=qnx

You will need to create a true ramdisk and tell Qt runtime where it is...
export TMPDIR=/ramdisk

If using QML, you must deploy your content directory to the target and start your app from that directory.

http://dl.dropbox.com/u/13676760/Qt_debugging_rev2.pdf covers this starting around page 5.

Re: Qt Target Library Location?   
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 :)

Re: Qt Target Library Location?   
/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.

Re: Qt Target Library Location?   
"waitfor" is used in boot scripts.  If you run the commands from a shell you would omit it.

Re: Qt Target Library Location?   
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.

Re: Qt Target Library Location?   
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

Re: Qt Target Library Location?   
>>>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)

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?

also As far as I understand, i will add this code bsh file

i will runing this code on command prompt

dinit -hq /dev/hd1t77
mount /dev/hd1t77 /ramdisk
export TMPDIR=/ramdisk

or i will add all code to bsh file?

Do I understand correctly?

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

Re: Qt Target Library Location?   
Yes, in a script you need waitfor.  When creating by hand from a shell you can't use waitfor as you noted previously.
