Description Axel Thimm 2006-08-05 05:33:41 EDT
Description of problem:
/usr/include/python2.4/pyconfig.h is now a wrapper for 32/64 bit sub-includes.
This breaks the usual query mechanism for extracting python build flags.

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

How reproducible:

Steps to Reproduce:
1.config_h = sysconfig.get_config_h_filename()
2.config_h_vars = sysconfig.parse_config_h(open(config_h))
Actual results:

Expected results:
{'STRICT_SYSV_CURSES': "/* Don't use ncurses extensions */", 'HAVE_SELECT': 1,
'HAVE_ST_BLOCKS': 1, [...]

Additional info:
o Breaks builds of smart package on FC6
o One can argue that the bug is in the implementation of parse_config_h, which
  should be able to descend into further included files. OTOH it would then need
  to understand nested conditionals, too.
o maybe the 32/64 bits switch should be performed already on 
  get_config_h_filename level? E.g. get_config_h_filename should return
  pyconfig-32.h and pyconfig-64.h respectively?

Comment 1 Axel Thimm 2006-08-05 06:07:33 EDT
Turns out this is due to the fix for multilib -devel support in bug #139911
comment 2. This fix only considered C/C++ consumers of pyconfig.h. python's
querying mechanism needs to be redirected, too, by patching
get_config_h_filename. A simple untested specfile fix is in bug #139911 comment 4.
Comment 2 Mihai Ibanescu 2006-08-17 18:18:16 EDT
Fix (based on your suggestion) included in python-2.4.3-15 - thanks!
Comment 3 Axel Thimm 2006-08-18 18:54:25 EDT
This fixes bug #201435, thanks!
Wrt to organisation, I'll just go ahead and close #201435 w/o removing the
dependency, I hope that's the proper procedure. Otherwise feel free to remove
the dependency. Thanks, again!
