This also worked for me. Thanks so much. I did however have to make one change, I had to quote the line that exported CXX:
export CXX="g++ -arch i386 -arch x86_64"
I am pretty sure that I've got other issues, but gcc didn't work for me. I wound up replacing gcc and g++ with clang.
Good catch, it should have been quoted.
It works, thank you
thanks !
This didn't work for me, I ran into issues on the final step with errors like these when compiling
/System/Library/Frameworks/vecLib.framework/Headers/vBasicOps.h:153:23: error: immintrin.h: No such file or directory
Ended up going with this - http://fonnesbeck.github.io/ScipySuperpack/
quick question - which version of numpy does this install?
Excellent, thank you!
On my system (Mavericks 10.9.2 with latest update for Command Line Tools) I had to use
export CC=gcc
rather than
export CC=gcc-4.2
@fogathmann 👍 I had the same issue, works like a charm!
I've been having this same problem, for pretty much any packages which build C/C++ code. I made a small wrapper around this process so that pip
gets the right environment directly. It seems to work OK for me, and makes it less annoying to manage the shell variables on a per-session basis.
I have some problem with Cpython . any got any solution:
Searching for cython
Reading http://pypi.python.org/simple/cython/
Best match: Cython 0.20.1
Downloading https://pypi.python.org/packages/source/C/Cython/Cython-0.20.1.tar.gz#md5=52431696c64e618036537c4d9aa79d99

try this?
export CFLAGS="-arch i386 -arch x86_64 -Qunused-arguments"
export CPPFLAGS="-Qunused-arguments"
Thanks a lot!
and thank you @fogathmann it works for me
Thank you, this solution works for me.
