How to build 32bit python 2.6 on 64bit Linux ?

Question

Hi folks,

I'm stuck for a full afternoon now trying to get python to build in 32bit mode. I run a 64bit Linux machine with openSUSE 11.3, I have the necessary -devel and -32bit packages installed to build applications in 32bit mode.

The problem with the python build seems to be not in the make run itself, but in the afterwards run of setup.py, invoked by make.

I found the following instructions for Ubuntu Linux: h**p://indefinitestudies.org/2010/02/08/how-to-build-32-bit-python-on-ubuntu-9-10-x86_64/

When I do as described, I get the following output:

But I have the -32bit packages of libreadline, libopenssl, etc.pp. installed, but of course, they reside under /lib and /usr/lib and not /lib64 and /usr/lib64.

When I start the python binary that results from this build, i get:

./python
Python 2.6.6 (r266:84292, Oct  5 2010, 21:22:06) 
[GCC 4.5.0 20100604 [gcc-4_5-branch revision 160292]] on linux2
Type "help", "copyright", "credits" or "license" for more information.
Traceback (most recent call last):
  File "/etc/pythonstart", line 7, in <module>
    import readline
ImportError: No module named readline

So how to get setup.py to observe the LDFLAGS=-L/lib command??

Any help is greatly appreciated.

Regards, Philipp
