Alright I’m pretty new to using VS. I’m trying to figure out the time elapsed between updates in an OpenGl program (in C), and I was planning on using timeGetTime().

I have 

#include <windows.h>

at the top of my program. As well under “Project>Properties>Linker>Input”, I have “Additional Dependencies” include “winmm.lib”. Now whenever I try to use timeGetTime(), it gives me two errors:

Error   63  error LNK2019: unresolved external symbol _timeGetTime referenced in function _main ***.obj

and

Error   64  fatal error LNK1120: 1 unresolved externals C:\***

How do I get around this?

    Make sure you don’t have WIN32_LEAN_AND_MEAN or MMNOTIMER macros defined, or the prototype for timeGetTime() won’t be included in mmsystem.h .

    Another possibility is that you have some other declaration for timeGetTime() in one of your headers (or the .c source file) that’s being picked up for some reason instead of the declaration in mmsystem.h.

    The symbol that should be looked for by the linker is:

    __imp__timeGetTime@0 (or __imp_timeGetTime on x64)

    not

    _timeGetTime
