I was under the impression that including the header file allowed you to use those functions. What exactly does linking to the library do? [EDIT] Thanks btw! baldurk 2006-06-10 09:40:09 UTC #6 @poita Oh ok. I was under the impression that including the header file allowed you to use those functions. What exactly does linking to the library do? [EDIT] Thanks btw! The way the build system works is http://forum.devmaster.net/t/unresolved-external-symbol--direct3dcreate9-4/9988 in a couple of major parts (not counting the preprocessor and suchlike). First, the compiler will take the raw source code and convert it into an object file. This is why you need to include header files. The header files contain the declarations of the functions you're using. ie. the header files say to the compiler, "there is such a function matching this prototype - if it gets used, don't give an error". If you didn't include the header, or used the function wrongly, the compiler would tell you about it. However, these object files themselves don't make your program. That's why you need the linker. The linker takes the object files and combines them into the final executable. It also defines in the executable every single function your program calls. So if you call printf, it defines that your program needs to link to the standard c library at runtime (which I think is msvcrt on windows - MS visual c run time?). Then, if you call Direct3DCreate9 the linker will define that you need to link against d3d. However, it can't work that out automatically. You need to tell it that you're using d3d in your program. That way it can resolve all the symbols in the object files and properly li

Help! Hey there, I am trying to create a Direct3D program, however error lnk2019 unresolved when I try to compile and run the program I get the following error: PainterlyRenderer error LNK2019: unresolved external symbol _Direct3DCreate9@4 referenced in function "int __cdecl InitInstance(struct HINSTANCE__ *,int)" (?InitInstance@@YAHPAUHINSTANCE__@@H@Z) It seems that my program does not like the call to Direct3D_Object = Direct3DCreate9(D3D_SDK_VERSION); that I have defined in my program.
