Qt 5.3 build from Qnx : unable to run   
Hello, 

I was working with a personnal compilation of Qt 5.3.
Then I tried Qnx's compilation... impossible to run my application (called Screen) on my imx6 board:
This application failed to start because it could not find or load the Qt platform plugin "qnx".

Here is the output of the console using QT_DEBUG_PLUGINS = 1

Any ideas ?

Re: Qt 5.3 build from Qnx : unable to run   
What is the value of the QT_PLUGIN_PATH env var in the shell where you start the app?

The same I posted earlier : /mnt/sdhc/graphics/opt/qt5/plugins

I even tried to put it again in Qt Creator unduer Run Environment options... but nothing...

RE: Qt 5.3 build from Qnx : unable to run   
Try LD_DEBUG=libs <name of app> it will show you what libs it's trying to load. I saw the claim "plugin not found" 
because the system was not smart enough to show what really is missing (e.g. libfontconfig)

Re: RE: Qt 5.3 build from Qnx : unable to run   
Good point! But this is valid only for libs loaded by QPA (the "qnx" platform plugin). libfontconfig is loaded esle 
where.

Re: Qt 5.3 build from Qnx : unable to run   
You usually do not need to set QT_QPA_PLATFORM_PLUGIN_PATH. QT_PLUGIN_PATH should be sufficient. Which SDP are you on? 
Why is all this QWS* stuff in? I greatly doubt Qt5 will work on QWS... QWS was in use before QPA came up

Re: Qt 5.3 build from Qnx : unable to run   
It is coming from Qt 4.8 on SDP 6.5

Now we're running on SDP 6.6 (without Apps and Media installed for now)
but the old env var should come from old setup...

with LD_DEBUG set to libs Screen :

Re: Qt 5.3 build from Qnx : unable to run   
Then your build was made with fontconfig, but it is not available on the target. This is strange since you say, you do 
not use Apps&Media for now. Did you add fontconfig on your own?

Re: Qt 5.3 build from Qnx : unable to run   
Sorry, I now read your first post more carefully. The build provided by QNX is made with Apps&Media. It is not going to 
work on a target which does not have it on board. You need to make your own build again if you do not like/need/may use 
Apps&Media.

Re: Qt 5.3 build from Qnx : unable to run   
You got it right !

libfontconfig and libfreetype were missing but after a quick copy and the copy of correct fonts it is now working great 
:) !

Fonts are much sharper, really nice.

Thank you very much for your help.
