        Hi there,

        you don't give a lot of details, but CC as opposed to cc is a common
        name for C++ compilers. You can not use a C++ compiler to
        compile GRASS (ANSI C is a near subset of C++, but GRASS is mostly
        K&R, which is incompatibly for the style of function declarations 
        alone...)

        However, most C++ compilers have no problems with linking libraries
        written in C, as long as they see the correct function prototypes
        adorned with 'extern "C"'.

        Have a look at the file grass-defs.h on grass/incoming (*),
        this provides prototypes suitable for inclusion in C++ programs.
        Use

        extern "C" {
        #include "grass-defs.h"
        }

        Let me know if this works for you.

        Martin

        (*)That's on the moon, but seeing that you post from Norway,
           ftp://ftp.informatik.uni-kiel.de/pub/packages/grass/incoming
           might be faster.
