I don't know where that message came from, because --enable-cxx is not a gcc configure option, see http://gcc.gnu.org/install/configure.html > So I obeyed then. I expected it would generate the proper files needed for a > C++ binding to gmp. GCC doesn't need a C++ binding to GMP. > Unfortunately, I may have lost track of which "configure" script was needing > gmpxx.h. My ppl/cloog-ppl libs were compliant with those advised in the > pre-requisites (0.11.2 and 0.15.10). cloog and ppl are optional, if you can't get it to build with them why not try without them?
