Did I > set the global variable wrong way? Yes. Makefiles do not use values from the environment by default. If you don't need libcc1 you can just configure with --disable-libcc1 to skip building it. Alternatively, --with-pic might help, or setting CXXFLAGS as a Make variable instead of environment variable might work: make CXXFLAGS="-fPIC -O2 -g" >
