This was tricky one.

The problem is that CLANG treats include files case insensitive. Thus <mysql/mysql.h> in fact included the package's MySql.h recursively...

I have fixed it by redoing the code to:
#ifdef PLATFORM_POSIX
#ifdef PLATFORM_OSX
#include <mysql.h>
#else
#include <mysql/mysql.h>
#endif
#endif
so with MacOS you will need to point to inside that mysql folder. Not nice, but for now it will do.

Thank you very much!
Now I was able to overcome the include problem... but unfortunately I stopped again at the lib. Below are the new complains.

Can I ask you which library you have installed and where point your path lib? I tried with all the library I have but nothing happened. Perhaps I need to set some flag or compiler option.
