multiple definition errors

[omerbrandis]

hi,

I'm having some problem using the lib on linux ubuntu.
I've built a very simple CMakelists.txt that simply compiles the cpp files in the src folder.

then , in another project ( also ubuntu & cmake, cpp 17 )
included the headers & objects and wrote some very simple code

#include "ColorSpace.h"
ColorSpace::Rgb TempRGB;

the build failed with
ColorSpace.cpp: -1: error: multiple definition of `ColorSpace::Rgb::Rgb()'
which is somewhat surprising since I see that the file has include guards.

should I have addressed
typeinfo.h:

#ifndef __GXX_MERGED_TYPEINFO_NAMES
// By default, typeinfo names are not merged.
#define __GXX_MERGED_TYPEINFO_NAMES 0
#endif

// By default follow the old inline rules to avoid ABI changes.
#ifndef __GXX_TYPEINFO_EQUALITY_INLINE
  #if !__GXX_WEAK__
    #define __GXX_TYPEINFO_EQUALITY_INLINE 0
  #else
    #define __GXX_TYPEINFO_EQUALITY_INLINE 1
  #endif
#endif

?

thanks,
Omer.
