I had the same problem time ago, with another program and another
C/C++ compiler.

If I remember well, the problem is you should use the following:

/* C++ wrapper */
#ifdef __CPLUSPLUS__
extern "C" {
#endif

/*
 * ...Header file contents...
 */

#ifdef __CPLUSPLUS__
}
#endif

/* C++ wrapper */

in every header file.

If I am wrong, will someone please tell me?
I never understood completely the meaning of that ``extern "C"'' I
often find in header files...

All the best

  Massimiliano
