Hi Antoine,
Please see if the same issue occurs when you run our sample. It can be found here: Native_SDK/examples/OpenGLES/BinaryShaders at master · powervr-graphics/Native_SDK · GitHub
If the sample works on your hardware then you can try using your compute shader with it. This will let us know if the issue is caused by the binary conversion of the shader. If you encounter any problems running the sample then please send us your compute shader for us to test.
The supported extensions includes: GL_IMG_program_binary, and GL_OES_get_program_binary
The prefix for the GetProgramBinary extension is OES while the prefix for ProgramBinary is IMG. The binary format might not be compatible between these two extensions. If these are the only supported extensions for GetProgramBinary and ProgramBinary then the issue may be with the driver not supporting matching types or not reporting all the extensions correctly.
Regards,
Thomas
