First of all, make sure you don't install binary packages and wheels. Changing the C compiler flags will require source builds. Then, it should be enough to set the CFLAGS environment variable, e.g. CFLAGS="-O3 -march=native" pip install --no-use-wheel numpy Stefan -- https://mail.python.org/mailman/listinfo/python-list
