Opengl examples of Qt5 not working

Sujith Haridasan

Hi,


The opengl examples of Qt5 (version 5.3.2 from meta-qt5 layer) are not working when executed on machine: beaglebone black. I am using libgles version 5.1.1.1. Below is the log:

root@mel-am335x-boneblack:/usr/share/qt5/examples# ./opengl/hellowindow/hellowindow -platform xcb
Qt Warning: Could not find a location of the system's Compose files. Consider setting the QTCOMPOSE environment variable.
Qt Warning: Could not find a location of the system's Compose files. Consider setting the QTCOMPOSE environment variable.
Cant find EGLConfig, returning null config
Cant find EGLConfig, returning null config
EGL did not suggest a VisualID (EGL_NATIVE_VISUAL_ID was zero) for EGLConfig 0
Unable to find an X11 visual which matches EGL config 0
Could not initialize EGL
Aborted
root@mel-am335x-boneblack:/usr/share/qt5/examples#

I am bit worried with this behavior. Because qtdeclarative examples are also not working because of this. A I am running it on X11 using core-image-sato image from poky.

May I know if anyone had faced this issue before? Any helping hand to resolve this issue would be great. If any more information is required do let me know.

Thanks,

Sujith H

    Hi Sujith,

    Please follow strictly installation and user guide for posted sites. I followed them and successfully build it on my am335x evm board.

    Also let's try to look your qmake.conf file explaining:

    Hi Ivan,

    I don't have problem with building Qt. Most of the examples built from meta-qt5 layer are running properly in the X11 based core-image-sato. The only problem I face is with opengl examples. And when I was going through the link: http://processors.wiki.ti.com/index.php/Sitara_Linux_Training:_Hands_on_with_QT, I find that:
    [hellogl_es2]
    WindowSystem=libpvrQWSWSEGL.so.1

    to be used. Isn't libpvrQWSWSEGL.so.1 for wayland? I am not using wayland in core-image-sato image. So my question is whether I would be able to run opengl examples of Qt 5.3.2 on X using libgles 5.1.1.1?

    I forgot to mention that I am using poky to build the core-image-sato image.


    Thanks,
