Python: how to import 32bit module for 64bit python

Question

Due to the system limits, I can only use a 64bit version Python, though, some of the modules that I intend to use do not come with a 64bit version (eg httplib2). In this case, what am I supposed to do so as to leverage those 32bit functions?

Thanks for the answer by j_mcnally. That works. Another approach that eventually works for me is to use the prefix parameter if there are multi-versions(eg 32/64) of python installed:

python setup.py install --prefix = "your python root directory"

Answer 1

Excuse my ignorance, but can't you compile them as 64 bit modules?

http://code.google.com/p/httplib2/

the source is there. I would image most modern ./configure scripts will detect your arch, and compile the appropriate extension.

the following seems to work for me:

ARCHFLAGS='-arch x86_64' python setup.py install

running install running bdist_egg running egg_info writing

python2/httplib2.egg-info/PKG-INFO writing top-level names to

python2/httplib2.egg-info/top_level.txt writing dependency_links to

python2/httplib2.egg-info/dependency_links.txt reading manifest file

'python2/httplib2.egg-info/SOURCES.txt' reading manifest template

'MANIFEST.in' writing manifest file

'python2/httplib2.egg-info/SOURCES.txt' installing library code to

build/bdist.macosx-10.8-x86_64/egg running install_lib running

build_py creating build creating build/lib creating build/lib/httplib2

copying python2/httplib2/ init .py -> build/lib/httplib2 copying

python2/httplib2/iri2uri.py -> build/lib/httplib2 copying

python2/httplib2/socks.py -> build/lib/httplib2 copying

python2/httplib2/cacerts.txt -> build/lib/httplib2 creating

build/bdist.macosx-10.8- x86_64 creating

build/bdist.macosx-10.8- x86_64 /egg creating

This guy has made a windows installer (see Base-12.9.15.win-amd64-py2.7.‌exe at the bottom) for many, many modules used in scientific python. Consider using it, if you're not comfortable compiling from source.
