Compiling C++ files with gplc

[Jay Bradley]

I was wondering if anyone out there could help me. I'm sure someone must have 
come across this problem before.

I am trying to compile two files using gplc. One is a prolog file and compiles 
fine. The other is a C++ file and will compile but will not link.

I am using the command:

gplc -v --c-compiler g++ threeBody.c threeBrain.pl

where threeBody.c is the C++ file and threeBrain.pl is the prolog file.

I get the following (rather long) error message:

Note that it compiles fine but will not link. It will not even link with the 
C++ libraries by the looks of it. I also note that it uses gcc at the linking 
stage. I can't work out how to change this if it even matters.

I'd be very grateful if anyone could help me.
