Bug 120829 – libselinux 1.28 appears to have hardcoded Python-2.4 dependency

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Ed Wildgoose 2006-01-29 09:50:43 UTC]

Have been bashing my head wondering why the standard stage 3 hardened stage rebuild subsequently fails when I run "emerge -e system", always falling over when building libselinux

The problem appears to be that when everything is rebuilt, libselinux is upgraded from 1.22-r1 to 1.28 and the newer libselinux appears to die needing "/usr/include/python2.4/Python.h".  The default version of python is 2.3 on the current hardened stages.

I think it's swig which is hardcoded to need python2.4, but something is explicitly setting the build command line to look for Python.h in the /usr/include/python2.4 directory - which does not exist in the standard stage

I simply did an "emerge python" and upgraded to 2.4 and not libselinux builds OK.

I think this is a higher severity than normal because it appears to hit anyone downloading and trying to use the current hardened stages.

The first issue is possibly that libselinux seems to need swig (and this is not listed in the ebuild dependencies).  The second thing is that something is hardcoding in the paths for Python 2.4 as part of the build

Probably someone who knows these ebuilds better can quickly point out the best place to add in the missing dependency statement


The errors look like this:

python version handling fixed, added swig dependency.
