compilation problem on Mac

[karimtarbali]

Hi José,
I was trying to install shakermaker on my Mac (Ventura osx ) with Intel processors, but after many tries, I still get errors as below when I run 'python setup.py install'. I am wondering if you happen to come across this error in the setup stage. This is most likely mac-specific/clang/gcc related issue.

I get similar Warnings on Linux, but seems like the sutup ends ok. here is the snapshot of the text from the terminal

a general question, Does ShakerMaker work only with python2 or can work with python3 as well? (FYI- i am using python3.10 on mac and linux)

It seems to be a problem with the default compiler flags picked up by numpy.distutils. From the command line before running setup try the following:

export CFLAGS="-O3 -Wall"  # Add any flags you need here
export CXXFLAGS="$CFLAGS"
export FFLAGS="-O3"
python setup.py install --user 

This theoretically overrides the flags picked up by numpy. You can then add the flags suggested during the compile process, except the "avx512" ones that were offending. See how it goes.
