compile error with brew gcc (mac yosemite)

[ryanvarley]

Running the compile command in the readme

python setup.py config_fc --fcompiler=gnu95 --opt="-Ofast" --f90flags="-cpp -fopenmp -march=native" build

I get

...

Any ideas?

I haven't tried building the package on a Mac myself, but geoffgrimwood sorted this out with his Macbook by adding -mno-avx to f90flags. That is,

python setup.py config_fc --fcompiler=gnu95 --opt="-Ofast" --f90flags="-cpp -fopenmp -march=native -mno-avx" build

If this still doesn't work, remove -march=native and set -Ofast to -O3 (or lower.)

[ryanvarley]

running the new command without -march=native worked and the tests pass.

python setup.py config_fc --fcompiler=gnu95 --opt="-Ofast" --f90flags="-cpp -fopenmp -mno-avx" build

thanks!
