The internal compiler error is something we are all running into right now.
 The only known fix is to run the build with the gcc flag "-Os" instead of
"-O3". You should be able to do this by setting the environment during your
build:
CFLAGS="-Os" python setup.py build

Thanks, and I have had success with various packaged versions,
but I want to be able to update and compile the svn version
at will, just like I can under linux.
still stuck,...
Jules

Yes. I'll fix that. Thanks.

Thanks, that worked!
Small note, the example matplotlibrc file on the website 
(http://matplotlib.sourceforge.net/matplotlibrc) as well as the one in the most 
recent mac OS egg has "svg.embed_chars".
Thanks

Hi Mike,
Thanks for the tip. I tried it, but I get the following message:
Bad key "svg.embed_chars" on line 294 in
/Users/kghose/.matplotlib/matplotlibrc.
You probably need to get an updated matplotlibrc file from
http://matplotlib.sf.net/matplotlibrc or from the matplotlib source
distribution
The text is still exported as path.
Thanks

The rcParam svg.embed_chars controls this behavior. I would assume it 
is set differently on your Windows and Mac boxes.
When it is True, rather than outputting <text> blocks, it embeds the 
characters as outlines. This means that the fonts do not have to be 
installed just to view the SVG correctly. The upside is better 
"portability" of the file. The downside is that the text can be 
impossible to edit in tools such as Inkscape or Illustrator. (Using SVG 
fonts would have been better, but there isn't much support for them in 
the wild yet).
When it is False, regular text blocks are used, but things will look 
strange (particularly with math text) if the correct fonts are not 
installed on the viewer's machine.
Hope that helps.

Sorry about that. That comes from switching between Python and C/C++ 
all the time. I have updated SVN to reflect this.

round() is defined in math.h so adding
#include <math.h>
to the top of the file might fix it.

Hi Jules,
I've been making the migration to mac recently myself. I have OS 10.5.2 running 
on Intel.
If the source of your distribution is not an issue, I would recommend using
matplotlib-0.91.2-py2.5-macosx-10.3-fat.egg
from the matplotlib site, along with the easy_installer script.
That went fine for me.
Thanks

Hi Everyone,
I'm using matplotlib on mac (matplotlib-0.91.2-py2.5-macosx-10.3-fat.egg) .
On windows svg export would have very sensible text grouping. For example an 
xlabel('Time') when saved to svg results in one text object 'Time'.
In the mac version this is saved as 5 separate objects, not text. A little 
puzzling, and inconvenient.
Is there an option somewhere to change this behavior?
I'm attaching an example svg.
Thanks!
-Kaushik

Hello OSX SVN MPL users
I am following the instructions on
http://ipython.scipy.org/moin/Py4Science/InstallationOSX
and ran into some trouble.
The computer is a 13" intel macbook,
OSX 10.5.2 installed fresh in December 2007
Everything went reasonably well until I got to matplotlib.
I ran into an architecture incompatibility:
** ld: warning [snip] missing required architecture ppc in file
My notes, along with various comments and links to error output etc,
are contained in this link:
 http://currents.soest.hawaii.edu/misc/mins_notes/py4science_anotes.html
Any comments and/or help would be appreciated.
Jules
