It would be helpful to see a code fragment, however, it may just be a matter of 
having the appropriate function signature.  For example, to avoid the c++
function name mangling, in your header file use a construct such as
  
  #ifdef __cplusplus
  extern "C" {
  #endif

  int my_function( char * parameter );

  #ifdef __cplusplus
  }
  #endif

Then in your c++ implementation file, you would have,

  extern "C" int my_function( char * parameter ) {
        cout << parameter << endl;
        return 0;
  }

This can then be called from prolog using the normal c call interface.
