C2065 means that compiler does not see declaration or prototype of the function.
Make sure that spelling and letter case are correct. If namespaces are used you have to specify using namespace xxx.

Well..make sure that the path to the library is correct....furthermore...to add the library the following would be enough

#pragma comment(lib, "mylib.lib")

I never used the linker option to include a library, thus, it might work the same though...

According to DarkLotus post, the problem is with a compiler not a linker.

If compilation process were finished and library could not be found I think linker would generate error; probably unresolved external.

Therefore I still think that something must be wrong with declaration/prototype of mentioned function.

But we will know for sure when/if DarkLotus responds.
