Description Göran Uddeborg 2004-10-01 11:33:28 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.4.3)
Gecko/20040803

Description of problem:
To ensure backward compatibility, a Python 2.2 package is needed in
addition to the standard Python 2.3.  Applications built on RHEL3 with
an embedded Python engine will not be able to run on RHEL4 otherwise.


Version-Release number of selected component (if applicable):
python-2.3.4-10

How reproducible:
Always

Steps to Reproduce:
1. Compile the attached program on an RHEL3 system with the command

cc -I/usr/include/python2.2 demo.c
/usr/lib/python2.2/config/libpython2.2.a -ldl -lpthread -lutil -lm -o demo

2.Run this on RHEL4 (beta): ./demo

Actual Results:  
schiphol> ./demo
Could not find platform independent libraries <prefix>
Could not find platform dependent libraries <exec_prefix>
Consider setting $PYTHONHOME to <prefix>[:<exec_prefix>]
'import site' failed; use -v for traceback
Traceback (most recent call last):
  File "<string>", line 1, in ?
ImportError: No module named os


Expected Results:  
Just the string

  posix

as if the program is run on RHEL3.

Additional info:

It would not help to fiddle with PYTHONPATH so demo would find the
Python 2.3 modules; the 2.2 engine can not load 2.3 modules.

It appears as it would be easy for Python 2.2 and Python 2.3 to
coexist.  Almost everything, except for the /usr/bin/python and
/usr/bin/python2 executables, contain the 2.3 version number in the path.

Red Hat does not guarantee binary compatibility across major releases for all
packages.  For an explanation of Red Hat's compatibility support across major
releases, see the Red Hat Enterprise Linux 4 Application Compatibility Whitepaper:
