I'm getting this error message:
winmain.obj : error LNK2019: unresolved external symbol _D3DX10CreateEffectFromFileW@48 referenced in function "long __cdecl InitDevice(void)" (?InitDevice@@YAJXZ)
I've spent days trying to find what the problem is and I found that I'm probably missing a lib file, however, I have no idea which one.
Here's my code:
