Help please!!! Compile and then run the application in qnx!!!
-
Hi portoist,
I'm certainly not new to Qt on Windows and Unix/Linux, but I am new to Qt on QNX and new on this forum. I am also new to the company I work for now, where we try to switch from Photon to Qt.
I was able to configure and build the Qt library on a Windows 7 PC, with this configuration:@configure -opensource -platform win32-g++ -xplatform qws/qnx-i386-g++ -no-exceptions -qt-zlib -qt-libpng -qt-libmng -qt-libtiff -qt-libjpeg -no-qt3support -arch i386 -no-inotify -no-iconv -opengl es1 -no-xmlpatterns -nomake examples -D QT_NO_GLIB@
We work with QNX Momentics and I was able to build an application after having added the Qt include and lib directories to the project properties. I copied the Qt libraries to the QNX (virtual) machine, moved my executable to the QNX machine and tried to execute it. It aborts with the following errors:
Failed to load platform plugin "qnx". Available platforms are:
Abort (core dump)
After having read some items on the internet I copied
C:\Qt\4.8.5-qnx\plugins\platforms\libqminimal.so
to
/usr/lib/Qt/plugin/platforms/but that didn't help.
I understand that you have got it working. Could you please help me out. I would be very grateful.Thanks,

Hello,
I am using virtual machine with linux and Momentics SDK to compile Qt for QNX (And also to create binary of my App), here is my configure line:
@
configure -xplatform qws/qnx-i386-g++ -embedded i386 -no-gfx-linuxfb -no-mouse-linuxtp -no-kbd-tty -no-qt3support -qt-gfx-qnx -qt-mouse-qnx -qt-kbd-qnx -no-exceptions -opengl es2 -nomake exapmles -nomake tests -nomake demos -nomake webkit -qt-gfx-vnc -opensource
@
Then to run app on QNX target I have to kill Photon and execute app with -qws. Also set these:
@
export QWS_DISPLAY="VNC:qnx"
export QWS_KEYBOARD=qnx
export QWS_MOUSE_PROTO="qnx:/dev/devi/touch0 qnx:/dev/devi/mouse0"

Hi,
Thanks for your fast reply. I tried killing Photon (>slay Photon), but that killed everything immediately and shutdown the machine. I set the QWS environment variables. I don't have devi/touch0 and devi/mouse0 devices, so I don't know whether that will have any effect. Alas, executing my app with the -qws option did not work for me.
I will try your configuration parameters, though I know that a number of them will not be accepted by the Windows version of configuration. But I give it a try anyway. -
Well this is what we are using:
@
slay Photon
sleep 2Start keyboard and mouse driver
/usr/photon/bin/devi-hid -Pr kbd mouse
Start touch driver
/usr/photon/bin/devi-elo -Pr smartset -b9600 -R fd -d/dev/ser2 abs -f/etc/calib
@
Instead of killing photon you can try ending session in Photon environment - you click on some exit button and then you can choose if you want to logout, or logout and exit Photon. I don't remember exactly, I am on holiday and don't have any QNX virtual with me to have a look:)
After starting keyboard,mouse and touch drivers it will look like freezed - but it isn't - you have to control your machine via telnet or ssh.
I would recommend you to try compiling Qt for QNX on linux, it's easier. -
Hi,
I was able to build the Qt library for QNX on Linux and run a demo Qt app on QNX without photon running. You were right to build the library on a Linux host, as you definitely need a number of configure parameters that the Windows version of configure doesn't support/understand.
At the moment I'm struggling to get a Qt app running with photon running as well. -
Hi Gentlemen,
I am trying to use Qt 4.8.5 on QNX 6.5-SP1 x86 platform (no photon), but always got error message.
#./configure -xplatform qnx-x86-qcc -opengl es2 -egl -no-cups -no-xcb -no-eglfs -no-javascript-jit -no-gtkstyle -no-iconvWhich edition of Qt do you want to use ?
Type 'c' if you want to use the Commercial Edition.
Type 'o' if you want to use the Open Source Edition.o
The specified system/compiler is not supported:
/tmp/qt-everywhere-opensource-src-4.8.5/mkspecs/unsupported/qnx-g++Please see the README file for a complete list.
But under mkspecs, it looks "qnx-x86-qcc" should work.
Could you guys give me a help?Thanks,

Hi Albert,
Just back from holidays, I saw your request for help. I think you should specify a different xplatform. I used '-xplatform qws/qnx-i386-g++'. I use the same Qt and QNX versions and it worked for me. This is the whole configure command I used:
configure -xplatform qws/qnx-i386-g++ -embedded i386
-no-gfx-linuxfb -no-mouse-linuxfb -nokbd-tty -no-qt3support -qt-gfx-qnx -qt-mouse-qnx -qt-kbd-qnx -no-exceptions -opensource -little-endianMind you: You should build this on a Linux box, since a number of parameters are unknown to the Windows version of configure.

Hi Marcel,
Thank you very much for your help.
Jan also gave me his/her configuration as:configure -xplatform qws/qnx-i386-g++ -embedded i386 -no-gfx-linuxfb
-no-mouse-linuxtp -no-kbd-tty -no-qt3support -qt-gfx-qnx -qt-mouse-qnx
-qt-kbd-qnx -no-exceptions -opengl es2 -nomake exapmles -nomake tests
-nomake demos -nomake webkit -qt-gfx-vnc -opensourceThey are all very helpful, thank you all.
Best regards,

Hello all,
Can anyone of you explain me how can i run my app developed in qt4.8 in QNX6.5. As i am trying to run my app. while photon is running, GUI is not coming.
These commands i added in /root/.profile
export QWS_DISPLAY=qnx
export QWS_KEYBOARD=qnx
export QWS_MOUSE_PROTO=qnx
export XDG_CONFIG_HOME=/root
export QMAKESPEC=/usr/qnx650/target/qnx6/usr/share/qt4/mkspecs/unsupported/qws/qnx-i386-g++These are the commands i am executing:
/usr/photon/bin/devi-hid -Pr kbd mouse
io-display -d vid=0x8086,did=0x27ae
./myapp -qwsOn the other side when i run same app in text mode i am able to get GUI but touch is not working. For touch driver i am executing this command:
/usr/photon/bin/devi-eGalax -Pr egalax fd -d/dev/ser2 abs &
Please help me, its very urgent
Thanks in advance
Abhishek
