[gambit-list] Issues building Gambit with --enable-cplusplus

Hello,

I'm trying to create a simple Gambit wrapper for the opencv library.  Opencv is written in C++ so I tried to build Gambit with the --enable-cplusplus flag.  I was hoping this would be easier than trying to build a Gambit wrapper around a C wrapper around opencv, but I haven't been able to Gambit to build with the C++ option.  I have no problems building Gambit with gcc, but g++ gives the errors below.
Is there more to a C++ build that I may be missing?  Is there an easier way to wrap a C++ library?  I included my compiler versions below as well.
Thanks for you help,Bob
