Hello,
I've built Qt 5.14 with these options:
./configure -opensource -nomake examples -nomake tests -confirm-license -opengl es2 -opengles3 -prefix ~/test/lib
When running the hellogles3 example, this works as expected on X11. When starting Weston on X11 and running the example with Wayland, I get the following:
$ ./hellogles3 -platform wayland Requesting 3.0 context QOpenGLShaderProgram: could not create shader program QOpenGLShader: could not create shader Shader Program link failed. ""
Is that expected? And if so, how can I adjust my setup for OpenGL ES on Wayland prior to the availabilty of the target hardware?
This is the Weston output:
