Qt 5.x & SGX

Hi Pavel,

I've download QT 5.1.1 and build with arm-aragon-linux

exactly as described in TI's sgx patch:

But I get the following errors and then it stops:

./configure -prefix /qt5_1_install/ -release -make libs -xplatform linux-arm-gnueabi-ti-g++ -opengl es2 -confirm-license -opensource -icu -no-xcb -no-pch -make examples -verbose

Also tried to apply the patches on qt5.1.1 as described but it fails.

Thanks,

Hi,

If we need OpenGL and QML does it mean Qt must support SGX ?

Is it OpenGL=3D=SGX ?

Regards,
Ran

Which toolchain exactly you are using?

I suspect that more recent toolchain is needed:

export PATH=<path to recent GCC toolchain>

TOOLCHAIN_PREFIX=/opt/linaro/gcc-linaro-arm-linux-gnueabi-2012.03-20120326_linux/bin/arm-linux-gnueabi

Can you check if there will be any improvements with the below toolchains:

1. arago-2011.09

2. Sitara toolchain:

Hi Pavel,

Thank you very much for the help.

After some struglling with the version patch's provided by prabindh which non could compiled according to instructions, I decided to try my luck with newer qt version. So I tried qt5.3.2, with the build is successful ! Though I still hope that no patch is required for TI's arm.

Anyway, on trying to run any of the examples in qt I get error:

" could not find or load the Qt platform plugin "xcb"

Although I build it with -no-xcb  (also prabindh configure examle for 5.1.1 is with -no-xcb)

Is there any idea if I can run any non xcb dependent example ?

Thanks,

Ran

Yes, Qt5 can be used on DM81xx devices.

SGX is a 3D Graphics accelerator that is programmed via OpenGLES API. Hence, you can say that SGX = 3D = OpenGLES.

There is no OpenGL support, TI SoCs support only OpenGL ES 1.1/2.0

Upgrading Qt is done via picking up the right Yocto recipes.

Hi Pavel,

I've followed the detailed instruction in

In this link prabindh   , even attached the exact binaries he compiled, so I used that files.

But on trying to example as he used in the tutorial:

root@dm814x:/examples/widgets/painting/basicdrawing# /bin/qmlscene /examples/declarative/animation/ -platform eglfs

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

QML debugging is enabled. Only use this in a safe environment.

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

Failed to load platform plugin "eglfs". Available platforms are:

Aborted

It seems as if LD_LIBRARY_PATH does not link to this .co , but trying to add the link to LD_LIBRARY_PATH, I still get the same error.

Is there any idea what's wrong ?

Thanks,

Ran
