Did you wrap the C-code function declarations with 'extern "C"'? If
you don't, the C++ compiler will 'mangle' the names (to allow for
overloading). Eg:
#if defined(__cplusplus)
extern "C"
{
#endif
int someCfunction(int arg1, double arg2);
int someotherCfunction(char *foo);
#if defined(__cplusplus)
}
#endif
