Hello!

I trying to compile Qt 5.0.0 for my am3517 kit.

I follow this instructions: http://gpupowered.org/node/16, but change some paths in qmake.conf for my system.

my qt-everywhere-opensource-src-5.0.0/qtbase/mkspec/linux-arm-gnueabi-ti-g++ file is:

load(qt_config)

I use this configure params (in qt-everywhere-opensource-src-5.0.0/qtbase):

./configure -release -make libs -xplatform linux-arm-gnueabi-ti-g++ -opengl es2 -confirm-license -opensource -no-xcb -make examples -verbose -no-pch

Qt is now configured for building. Just run 'make'.
Once everything is built, you must run 'make install'.
Qt will be installed into /usr/local/Qt-5.0.0

To reconfigure, run 'make confclean' and 'configure'.

After "make" & "sudo make install", i copy /usr/local/Qt-5.0.0 folder into targetfs.

In target command line:

root@am3517-evm:~# cd /usr/local/Qt-5.0.0/examples/opengl/hellogl_es2/

How avoid this errors?

P.S: Qt 4.8.5 works perfectly:

Is there a reason why you are specifying "-qpa" ? Did you try setting "QT_DEBUG_PLUGINS=1" and checking the output ?

Thanks for answer! It's realy help!

"-qpa" option is my wrong experiment :-)

I set "export QT_DEBUG_PLUGINS=1" and i see output:

How i see, i need copy libudev.so.0 file to my target filesystem from TI SDK (in my host machine):

sudo cp ~/ti-sdk-am3517-evm-05.05.00.00/linux-devkit/arm-arago-linux-gnueabi/usr/lib/libu* ~/am300/src/rootfs/filesystem/lib

Application is runing, but i have this troubles:

1) My display resolution is 800*600, but application runing at bigest resolution. how fix this?

2) I see squares instead of letters. How to customize fonts?

3) OpenGL context was not created. How correct load openGL?

hellogl_es2 is not a good example of the power of Qt5. Please try using QML examples, and examples like hellowindow.

Thanks for you reply!

Ok, i found in google, that applications consisting of many widgets could not be run (only one widget may be displayed with eglfs).

But i do not how fix font trouble (squares instead of letters ). While i start any Qt example, i see in terminal:

QIconvCodec::convertFromUnicode: using Latin-1 for conversion, iconv_open failed
QIconvCodec::convertToUnicode: using Latin-1 for conversion, iconv_open failed

Fontconfig error: Cannot load default config file

Hi Evgeny,

Did you solve your font problem ? I am facing the same issue but I am not getting "cannot load config file" error. Just black border empty squares instead of characters.

Tried setting QT_QPA_FONTDIR and copying fonts to qt5install/lib/fonts directory. Does not work. Fontconfig...yes in configure output for qt5 build.

Also fonts in examples does not work.

Any pointer would be greatly appreciated.

Thanks.
