Installing psyco for python on Snow Leopard

Question

I'm having some trouble installing psyco on my Macbook pro running Snow Leopard with python 2.6.1.

I've been trying to force python to run in 32-bit mode using the command

defaults write com.apple.versioner.python Prefer-32-Bit -bool yes

Further, I have tried the Macport py26-psyco, which seems to finish but the module cannot be found when compiling.

$ sudo python setup.py install
PROCESSOR = 'ivm'
running install
running build
running build_py
running build_ext
building 'psyco._psyco' extension

Answer 1

Try doing this before compiling: export ARCHFLAGS="-arch i386" then in the setup.py

replace extra_link_args = [ ] with extra_link_args = [ '-L/Developer/SDKs/MacOSX10.6.sdk/usr/lib' ]

then just run: python setup.py install

Hope this helps!

Answer 2

I ran into the same problem on my MacBook Pro using OS X 10.7.

I was able to compile it using "sudo python2.5 setup.py install"

Not it work's like charm. Hope this might help someone else.
