All of the pointing at explicit GCC paths and linking with explicitly GCC libraries is unnecessary and causing your problems. You should not do that on AIX or RHEL 4 or .... Using "g++" as the link command implicitly will link with the correct GCC libraries. Remove -L/opt/freeware/... and "-lgcc -lstdc++ -lsupc++" from your Makefile and try again. David
