I'm trying to use CPLEX within Python on Mac OS 10.7.5. CPLEX appears to only support a 32 bit python. I'm using this in a python shell to check if it's 32 bit:
import sys,platform; print platform.architecture()[0], sys.maxsize > 2**32
I've tried these 2 commands as suggested in man 1 python, but neither seem to force 32 bit:
export VERSIONER_PYTHON_PREFER_32_BIT=yes
defaults write com.apple.versioner.python Prefer-32-Bit -bool yes
The only thing that seems to work is this:
arch -i386 python
However, if I run a script using arch which calls other scripts, they all seem to start up in 64 bit mode. Is there another system wide variable to force it into 32 bit mode?
