Compile error on a library from github (subhook)

[warchief]

I am trying to compile this simple hooking library: https://github.com/Zeex/subhook

and I am getting these errors:

1>subhook.obj : warning LNK4006: subhook_new already defined in subhook_x86.obj; second definition ignored
1>subhook.obj : warning LNK4006: subhook_free already defined in subhook_x86.obj; second definition ignored

Has anyone used this lib before?

How do you build it ? What compiler / IDE and OS do you use ?

You get that kind of mess when people take short-cuts and include one .c file in another.

#ifndef SUBHOOK_SEPARATE_SOURCE_FILES

#if defined SUBHOOK_WINDOWS
  #include "subhook_windows.c"
#elif defined SUBHOOK_UNIX
  #include "subhook_unix.c"
#endif

#if defined SUBHOOK_X86 || defined SUBHOOK_X86_64
  #include "subhook_x86.c"
#endif

#endif 

Maybe you need to define (or not) SUBHOOK_SEPARATE_SOURCE_FILES

Looks like all I had to do is to only press "Include In project" on subhook.c after copying the source files into my project's folder.

Thanks for the answers above!
