Hello @ all,

I have followed Vladan instructions and i have been able to build qt-4.7.2 for X11. I have enable the xorg-imx driver and the amd-gpu-bin. When i run on the device the deform example using opengl, i get the following :

QEglContext::createSurface(): Unable to create EGL surface, error = 0x3003QGLContext::makeCurrent(): Cannot make invalid context currentQGLContext::makeCurrent(): Cannot make invalid context currentQGLContext::makeCurrent(): Cannot maNot all allocated memory blocks were freed.

Do you have any idea why this is happening ?

I have abandoned for the moment the idea of qt embedded since (in order to use opengl) i need to create my own qt gl plugin driver.

 

Thanks in advance for your help.

 

Best Regards,

Stavros.

I am seeing the same problem (Qt 4.7.4 configured with -opengl es2).

I am trying the default Qt 'affine' demo and click it's "Use OpenGL" button.

Anyone seen this and solved this?

Regards, Leon.

Display is normal, but "Use OpenGL" button is hidden.
Whether this is your situation ?
