Question

I have been attempting to build HLSL shader support into VLC player. I have hit a brick wall due to lack of utility methods in d3d9.h in MingW to load a .fx file and compile the shader. So under advise from VLC developers I borrowed the DX9 headers from Wine.

Now with the d3dx9.h include enabled I have lots of compiler errors in the form:

Description Resource Path Location Type /mingw/lib/gcc/mingw32/3.4.5/../../../../include/d3dx9core.h declaration for parameter "D3DXCheckVersion" but no such parameter ShadedDXPlugin line 475 C/C++ Problem

Can any body familiar with MingW, GCC, DirectX and Wine shed some light on getting HLSL shaders working via GCC ?

Answer 1

The VLC team has again come back with some marvellous suggestions and I would like them to get into the rat race of stackoverflow reputation at some point:

1) Compile the calls to DirectX shader loading and assembling into a separate MSVC based DLL s which can access the standard microsoft headers. Then link to this DLL from VLC.

2) Insert GetProcAddress trick to get D3DXAssembleShaderFromFile in the d3d9.h. The said function in a directx utility to produce an assembly shader from HLSL.
