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.

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