Issue 902065: fails building C++ extensions when configured --without-cxx (original) (raw)

building C++ extensions with python configured --without-cxx fails, because the installed config/Makefile has CXX set to the empty string. However at least on Linux it does work to build the python binary without C++ for not depending on libstdc++ but load/build a module which depends on libstdc++ (which gets linked by g++).

Editing the generated config/Makefile does solve the problem. Another solution might be to pass LDSHARED in the environment to distutils as it is already done for CC, CFLAGS, etc, but this requires interaction by the builder of the module.
