Thank you very much for your suggestion sir - this gives me exactly what I need in terms of troubleshooting direction!

Linking with g++ issues -lstdc++ but -lsupc++ is not getting brought-in. I have been trying to determine why this does not happen and how to fix it. I assumed (incorrectly) that it was related to some configuration files, but perhaps it has to do with libtool, collect2 or ld? Also please note that all these are static libraries because NEXTSTEP does not support building of shared libraries. > > > What I'm suggesting is that you need to investigate how libstdc++ is > built and whether it is being linked with -lsupc++.
