Hi, Dom.

Are you still having trouble? I've got a few examples lying around for
VC++, but I don't know what compiler you're using. I certainly second
Gert's suggestion about using .def files if you're in VC++.

If things still aren't working, you can use the extern "C" construct to
force your C++ compiler to use C names and calling conventions in most
compilers.

Just add something like

#ifdef __cplusplus
extern "C" {
#endif

/* C callable prototypes here */

#ifdef __cplusplus
}
#endif

to your header file around IDL_load() or the externally visible
functions. More info at

Best,
Rich
