This is the crucial bit.
Looks like you've set MPLCONFIGDIR to a read-only dir, or the
.matplotlib in the current dir or .matplotlib in your home directory
aren't writeable by the user running your python script. (I'm doing a
bit of guesswork here...)
What is it that you're trying to do?

Re: [Matplotlib-users] Compiler error on OS X 10.5.2 in agg
Zachary Pincus wrote:
Can you tell me where you specified the -Os option to gcc to escape
the problem?
So the compile that command that failed is printed right above the
error message it generated. (The long line that starts with
'gcc' ...). I just copied this command, edited the -O3 to an -Os, and
pasted that command-line back into the terminal. Total low-tech hack,
as I didn't want to much with the setup.py file to fix compile flags
on a per-file basis.
After that file is compiled manually, you can re-run 'python setup.py
build', and it will start up at the next step after the error.
I got the same error in another step, which was a bit trickier to
fix,
because for some reason, src/_image.cpp gets copied to src/image.cpp
on a temporary basis, and then compiled. (I presume the file isn't
also modified?) But after the compile errors out, the copy is
deleted,
so just pasting in the offending gcc command doesn't work. So I had
to
manually copy src/_image.cpp to scr/image.cpp, and then paste in the
modified gcc command.
Ugh! I'd really love some help reducing this to a test case that I
can
send to Apple.
I've got the same error(s) in the same situation (10.5.2). I haven't
seen it any other context nor have had any success in reducing to a
test
case, alas. Could this have to do with picking up libraries (from fink
or elsewhere) and/or different compiler versions? I've got XCode 3 and
gcc 4.0. (I've actually got the apple 4.2 preview release as well but
that craps out even earlier, I assume due to library version
mismatches...)
I'm pretty sure what I'm seeing isn't from Fink or other library
versions -- this was on a pretty clean 10.5 install. I'm using a
custom-built Python 2.5.2 instead of Apple's, so that required
installing a new version of readline, but other than that, the system
is plain vanilla.
Has nobody else built matplotlib from source on 10.5.2 lately?

[Matplotlib-users] How to fix Lasso example bug???
Hello,
What follows is the lasso example code that I am running. This is the
example the comes with the matplotlib examples code. It works fine
except when one clicks and does not move the mouse. It seems to hang.
I have traced it down to the self.canvas.widgetlock.locked() call within
the LassoManager method called onpress. The onpress method is
registered as a callback for a button press event. What I need to know
is how to determine which widget has the lock and how to release the
lock before returning from the callback so that everything will continue
to work.
If anyone knows how to fix this please send example code.
Thanks,
Len
#!/usr/local/bin/python
Simple hacked test case to add fake runs and print out selected point set.
Show how to use a lasso to select a set of points and get the indices
of the selected points. A callback is used to change the color of the
selected points
This is currently a proof-of-concept implementation (though it is
usable as is). There will be some refinement of the API and the
inside polygon detection routine.

[Matplotlib-users] Interrupted system call on Mac
Hi,
I'm working on a Qt/KDE based GUI for TinyERP called, KTiny. One of the users
has been trying the application on Mac and matplotlib crashes with the
attached backtrace. Backend is Qt4Agg.
Unfortunately I don't have access to a Mac machine, but could ask him to try
some things as he is very responsive. Has anyone an idea of what could be the
problem? The application works perfectly well on Linux. On Windows is
producing a segmentation fault, but that is an issue for another e-mail I
think.
Any ideas will be very welcomed. Thanks in advance!
