I've been using matplotlib successfully for some time on Win XP and think it
is great. I would like to use on my linux box (Slackware 12 + python2.5)
Either interactively, or in script, when the "show()" command is reached,
the plot seems to come up momentarily, but then vanishes and I get a
segmentation fault. This seems to be happen no matter what I am trying to
plot. It is always when it attempts to put the plot on the screen that it
fails.
A possibly similar fault has been listed earlier in this forum:
http://www.nabble.com/segfault-with-TkAgg-and-any-GUI-in-2.5-td9700130.html#a9712842
I have been working through some of the suggestions made in that case by
John Hunter:
Firstly I did following:
rm -rf the site-packages/matplotlib and build subdirs and did a clean
install of matplotlib.
I am upoading files with the outputs from the build and install. I can't see
any obvious errors in these but
perhaps someone can.
http://www.nabble.com/file/p17470177/build.log build.log
http://www.nabble.com/file/p17470177/install.log install.log
As suggested by John H. I Tried importing these packages individually, with
results as shown.
import matplotlib._image (no problems)
import matplotlib._transforms (no problems)
import matplotlib.backends._ns_backend_agg # for numpy (Failed: no module
named ns_backend_agg)
(I'm using numpy)
import matplotlib.backends._tkagg (no problems)
import matplotlib._agg (no problems)
Greatly appreciate any suggestions as to what I could try from here or what
other diagnostics I can provide.

Further to my original post...
I forgot to note that I have specified Tkagg as the backend in the
matplotlibrc file.
I have Tkinter installed and it works OK in other apps independent of
matplotlib.

Let's see if we can narrow tis down to a specific backend. Try
running http://matplotlib.sf.net/examples/simple_plot.py with
a few different backends:
python simple_plot.py --verbose-debug -dAgg
python simple_plot.py --verbose-debug -dPS
python simple_plot.py --verbose-debug -dTkAgg
python simple_plot.py --verbose-debug -dGTK
Do they all segfault, if not which ones do and post the debug output
for one that does.

I suspect this is another instance of this recently fixed bug:
http://sourceforge.net/tracker/index.php?func=detail&aid=1949982&group_id=80706&atid=560720
You can check out the SVN maintenance branch from here (which has this bugfix):
svn co https://matplotlib.svn.sf.net/svnroot/matplotlib/branches/v0_91_maint matplotlib-0.91.x
Let us know how that works for you.
We should soon have a release fixing this bug.
Cheers,
Mike

Sorry have not responded re this earlier - I have been off the air for a few
days.
First here are the debug outputs from the tests suggested by John.
http://www.nabble.com/file/p17584892/Agg.log Agg.log
http://www.nabble.com/file/p17584892/PS.log PS.log
http://www.nabble.com/file/p17584892/TkAgg.log TkAgg.log
http://www.nabble.com/file/p17584892/GTK.log GTK.log
Of these:
TkAgg fails with segmentation fault
GTK : No module named gobject (guess I'm not set up for GTK)
Agg and PS don't error, but dont appear to generate any output.
Secondly, regarding Mike's suggestion:
I'm keen to try out the maintenance release with bugfix as suggested..
Some advice on downloading pls....
Do I use subversion to download that release..?
Or is there a '.tar.gz' that I can download. ?
Thnx in advance

Since previous post I have installed subversion and installed the maintenance
release
matplotlib-0.91.x
This segmentation fault no longer occurs.
Thanks John and Michael for your help with this.
