Hi! I want to use the OPT/FOPT environment viariables to set compiler flags when compiling numpy. However it seems that they get ignored under python3. Using Ubuntu 14.04 and numpy 1.9.0, I did the following:
>export OPT="-march=native" >export FOPT = "-march=native" > python setup.py build # "python" executes python2.7 [...snip...] C compiler: x86_64-linux-gnu-gcc -pthread -fno-strict-aliasing -march=native -fPIC ^C obviously under python 2.7, the additional march flag works as expected. However, using python3: >export OPT="-march=native" >export FOPT = "-march=native" >python3 setup.py build [.... snip ...] C compiler: x86_64-linux-gnu-gcc -pthread -DNDEBUG -g -fwrapv -O2 -Wall -Wstrict-prototypes -g -fstack-protector --param=ssp-buffer-size=4 -Wformat -Werror=format-security -D_FORTIFY_SOURCE=2 -fPIC ^C obviously, the flags aren't used in python 3. Did I overlook something here? Do $OPT/$FOPT only work in Python 2.7 by design, is this a bug or did I miss something?
