shaders compiled by glslPrecompiler are not supported on WP8 about angleproject

[stammen]

I need to update the shader compiler code. For now, in Visual Studio, from the Debug menu select Graphics/DirectX Control Panel. Click on Edit List and select the glslPrecompiler.exe in the src/glslPrecompiler/Debug folder. Then Under Device Settings Select 9_3 for the Feature level limit. I will be updating the compiler app next week.

I just validated that this works. Please let me know if you have any more issues.

Ok, the error is gone, but glProgramBinaryOES still fails.
Using GL_LINK_STATUS I get the following message:
"Invalid program binary version.
Mismatched compilation flags."

I built glslPrecompiler with the following flags:
COMPILE_SHADER
USE_FEATURE_LEVEL_9_3
ANGLE_ENABLE_D3D11

Oops, nevermind. My mistake, passed the wrong length when loading the shader.
Thanks! :D

The instructions for glslprecompiler (in the README) say to use flag USE_FEATURE_LEVEL_9_3.

But, this flag has been removed from the codebase (Renderer11.cpp), making it useless.

The above solution does work, but if you add back this code, it also fixes it:

static const D3D_FEATURE_LEVEL sfeatureLevels[] =
{
#ifdef USE_FEATURE_LEVEL_11_0
D3D_FEATURE_LEVEL_11_0
#elif defined(USE_FEATURE_LEVEL_10_1)
D3D_FEATURE_LEVEL_10_1
#elif defined(USE_FEATURE_LEVEL_10_0)
D3D_FEATURE_LEVEL_10_0
#elif defined(USE_FEATURE_LEVEL_9_3)
D3D_FEATURE_LEVEL_9_3
#elif defined(USE_FEATURE_LEVEL_9_2)
D3D_FEATURE_LEVEL_9_2
#elif defined(USE_FEATURE_LEVEL_9_1)
D3D_FEATURE_LEVEL_9_1
#else D3D_FEATURE_LEVEL_11_0,
D3D_FEATURE_LEVEL_10_1,
D3D_FEATURE_LEVEL_10_0,
D3D_FEATURE_LEVEL_9_3,
D3D_FEATURE_LEVEL_9_2,
D3D_FEATURE_LEVEL_9_1
#endif
};

There is a new compiler program in the dev branch in src/winrtcompiler that is now working for winrt and wp8 shader compilation.
