   DirectX problem...
  Hello,    I am using DirectShow to render an animation to a Direct3d texture and I am having trouble setting up the build environment. I have followed the SDK documentation to-the-letter as far as I am aware but I keep getting the following Linker error:Compiling...CTextureRenderer.cppLinking...CTextureRenderer.obj : error LNK2001: unresolved external symbol "public: __thiscall BaseVideoRenderer::CBaseVideoRenderer struct _GUID const &,char *,struct IUnknown *,long *)" (??0CBaseVideoRenderer@@QAE@ABU_GUID@@PADPAUIUnknown@@PAJ@Z)Msvcrtd.lib(crtexew.obj) : error LNK2001: unresolved external symbol _WinMain@16Debug/StarChart.exe : fatal error LNK1120: 2 unresolved externalsError executing link.exe.If anybody has come across a problem like this I would greatly appreciate some help as this is really starting to annoy me!Thanks in advance.Mark Coleman 
  Try including dxguid.lib. Not sure if it will help you, but it fixed a similar problem I had with DirectInput. ;  you need to compile the dshow base classes (they are in the sdk folder) they generate two files strmbasd.lib (for debug builds) and strmbase.lib (for release builds)you need to link to these in your linker - or you can just do a pragma comment#ifdef _DEBUG #pragma comment ( lib, "strmbasd" )#else#pragma comment ( lib, "strmbase" )#endifhope that helps! ;  Thank you for your input both of you, but neither works!!I had already compiled the Base Classes, and adding dxguid.lib didnt help either!!I have no idea what is going on now...If anybody has any other ideas I am open to suggestion.Thankyou.Mark Coleman ;  I had the same problem so I built all available configurations Release, debug, Unicode as added the code listed above into my dsrender.h file and it worked.
