Error compiling Cython on Mac 10.6

Question

Trying to install Cython so I can use openKinect Python wrapper.

I downloaded Xcode from the appstore (no install options. lame).

Im getting the following compile errors when trying to install

I also tried easy_install and that failed as well.

Error Code below

Answer 1

Before your command (but after any sudo) put

env ARCHFLAGS="-arch i386 -arch x86_64"

(When installing, you may want to omit the arch you don't have)

I do not have a Mac, I'm just putting through advice from python easy_install fails with "assembler for architecture ppc not installed" on Mac OS X

Answer 2

I had the same issue (with Cython installation and other modules). Using krzysz00's advice, here are the exact steps (Mac OS X 10.6.8) :

$ uname -a
Darwin machine_name 10.8.0 Darwin Kernel Version 10.8.0: Tue Jun  7 16:33:36 PDT 2011; root:xnu-1504.15.3~1/RELEASE_I386 i386            
$ cd Cython-0.14.1
$ sudo su - 
# export ARCHFLAGS="-arch i386 -arch x86_64"
# python ./setup.py install
# exit
$
$ which cython
/usr/local/bin/cython
