Thread: Linker error in release but not debug

I'm getting Linker error LNK2001 when compiling my first DirectX app as Win32 Release, although it compiles fine under Win32 Debug, the project type is Win32 Application (Using MSVC++6.0 standard).

DirectDrawSprites.obj : error LNK2001: unresolved external symbol _DirectDrawCreateEx@16
DirectDrawSprites.obj : error LNK2001: unresolved external symbol _IID_IDirectDraw7
Release/Step2.exe : fatal error LNK1120: 2 unresolved externals

Most of the code is from a tutorial on www.sunlightd.com, slightly modified, it's attached to this post.

Thanks in advance fort any help

I get linker errors as well, stupid MSVC, its compiled fine so if the compiler can find the files for your functions why can't the linker.
If the source files for those functions wasn't there the compiler would give an error message saying undeclared identifier which it dosen't. I've looked under project settings in MSVC but it isn't obvious whats going on there. Also I've searched msdn webpage for documents about how to use MSVC, guess what nothing there, in fact its even more vague than the help you get with MSVC.
If I ever do find documents on using MSVC Ill post them.

this is just a guess but are you including all the lib file necessary

Thanks! Yeah the DirectX libs were'nt being included under the link tab for release, but its all compiling properly now.
