Python exec dir is hardcoded

[sadam]

On jaunty, I found I was unable to build any of the activities because sugar.activity couldn't be found. I discovered that sugar/activity.py was installed in install/lib/python2.6/dist-packages but that wasn't in my path (enter shell, execute python, import sys, print sys.path). Python 2.6 changes the exec directory in /usr/lib/pkgconfig/python2.6/pygtk-2.0.pc to
pyexecdir=${exec_prefix}/lib/python2.6/dist-packages
but /usr/lib/pkgconfig/python2.5/pygtk-2.0.pc has
pyexecdir=${exec_prefix}/lib/python2.5/site-packages

This logic is hardcoded in sjhbuild/config.py. Probably pkg-config should be used to set the appropriate directory in the path going forward.

Can you check if this works?

Nope. It generalizes the path to the approriate version of python, but doesn't change that for 2.6 the pyexecdir is dist-packages instead of site-packages.

print sys.path

What about this?

Sascha is our new jhbuild master ;)

revised patch for python 2.6 fix

[sascha_silbe]

Using my new patch, I was able to compile "read" on Ubuntu jaunty / amd64 (which failed before) and Ubuntu intrepid / amd64 (worked before as well).
It needs testing for i386, though (both Python 2.5 and 2.6).

As jhbuild itself (i.e. the upstream project) has the same issue, my patch contains a workaround for that.

[sascha_silbe]

There are several packages having Python 2.6 issues as well. Will file separate bugs.

[sascha_silbe]

Bug report for upstream Jhbuild filed as ​#575426.
Using sugar-jhbuild on Ubuntu Jaunty is still blocked by #538 (upstream bug), but we'll need to patch sugar-jhbuild as well, so a review of my patch would be great.

[sascha_silbe]

As #538 has been fixed, I could now verify correct operation of my patch and checked it in. Please try again (remove the entire "install" directory first).
Leaving this bug open for a second pair of eyes over my patch (AKA review).

[sadam]

I can confirm this as fixed.

[sascha_silbe]

I had to change the behaviour again to include both lib and lib64 for gtk-2.0 as different distros use different paths (lib64 on Fedora, lib on Debian-based). :-/
In git as commit 2d3c75cc829b7603d681fb08ec030523da28acb0 .

[sascha_silbe]

Has been committed quite some time ago, closing without review now.
