I include with this email the mysql.h header file. It seems that
there's this extern "C" { you mentioned there.
Please take a look at the functions definitions (the mingw compiler
doesn't complain about the struct definitions in this header file such as
"MYSQL" but does complein about the function definitions such as
"mysql_error"):
There's the keyword STDCALL defined previously in the header at:
#if !defined(__WIN__)
#define STDCALL
#else
#define STDCALL __stdcall
#endif
Could the problem be with this STDCALL?
Thanks again,
Josep

Hey Josep.
It seems that the libmysqld uses different name mangling and so Mingw can=
not
find the symbols. Check the header file to
see if there is something like: extern "C" {... .
If not, try to add these lines. (check other header files to see how).
And/or maybe the calling convention will need to be specified.
