In my Suse system I have these 2 versions of Python:

# which python2.6
# /usr/bin/python2.6

# which python2.4
# /usr/local/bin/python2.4

2.6 is the system one, and 2.4 was compiled by me.

If I try to import a package using the 2.4 version:

# python2.4 -c "import bz2; print bz2.__doc__"

I get the following error:

# ImportError: No module named bz2

What is the correct way to proceed with this?

@MohsenPahlevanzadeh I have no problems with system Python2.6, so the modules are installed. But I don't know how to handle it for Python2.4 –  ftkg Oct 15 '13 at 20:32
    
please refer to supported versions, some of module are supported from x and higher milestone of python. –  PersianGulf Oct 15 '13 at 20:34
    
If it is a manually compiled python installation, then you need to install the bzip2 and bzip2-devel packages and then recompile and reinstall python. –  forcefsck Oct 15 '13 at 20:47
    
I might be wrong, but don't you need to set PYTHONPATH correctly so that Python 2.4 looks in the right place? –  peterph Oct 15 '13 at 22:34

It would appear that there is a bz2module.c that comes with the Python 2.4 source, but does not appear to be compiled by default and there is nothing in Modules/Setup for it. Likely because the development package for bz2 is not installed by default. Try to find the bzlib.h file on your system:

$ find /usr/include -name bzlib.h

If that does not exist, then install the appropriate library package (libbz2-dev on Debian/Ubuntu).

After that try adding the following to Modules/Setup.local and then recompiling python 2.4.

bz2 bz2module.c

Tried that, but got errors during make :libpython2.4.a(bz2module.o): In function 'BZ2Decomp_decompress': /home/incoming/Python-2.4.2/./Modules/bz2module.c:1841: undefined reference to 'BZ2_bzDecompress' any idea? –  ftkg Oct 16 '13 at 15:20
    
It isn't failing on my side, so I'm not sure where the problem could be. Since the build is finding bzlib.h, the most likely reason is that there is a version mismatch between what you installed for the bzip2 development package and what is expected in Python. The version of libbz2-dev on my system is 1.0.6-1, what was installed on your system? –  Arcege Oct 17 '13 at 13:45
    
Just took an alternative path. But you're probably correct, will mark your answer. –  ftkg Oct 25 '13 at 19:19
