Functions in C++ files which should be called from Prolog must use C linkage, e.g.
extern "C" {
void myfun(long i)
{...};
};
To build a dynamic linked foreign resource with C++ code, you may
(depending on platform) have to explicitly include certain
libraries. E.g. on Sparc/SunOS 5.X using gcc:
% splfr .... -LD -L/usr/gnu/lib/gcc-lib/sparc-sun-solaris2.4/2.7.0 -lgcc
The library path is installation dependent, of course.
