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

I could never get your reconfigure trick to work. I keep getting the error below during the last make.
... g++ -Wno-unused -Wno-write-strings -O1 -fwrapv -fno-strict-aliasing -fno-trapping-math -fno-math-errno -fschedule-insns2 -fomit-frame-pointer -fPIC -fno-common -mieee-fp -mpc64 -rdynamic -I"../include" -o "gsi" _gsi.o _gsi_.o "../lib/libgambit.a" -lutil -ldl libgambitgsi.a _gsi_.o: In function `main': _gsi_.c:(.text+0x19): undefined reference to `___main_char' collect2: error: ld returned 1 exit status makefile:178: recipe for target 'gsi' failed make[1]: *** [gsi] Error 1 ...
Fortunately, the changes Marc made to the repo this morning fixed the errors I was getting. I'm able to make from-scratch now with the --enable-cplusplus flag in place.
Thanks for your help!
