This is almost certainly a typo. I guess you mean 'sys.platform'

This has nothing to do with the numerix setting. Check out
setupext.py and add an entry to the basedir dictionary to reflect your
local path information. If you get something that works, please post
it so we can include it in the standard distro.
Is there a reason you don't want to use the pre-built win32 binaries?
Most windows users are reasonably happy with that.

Ryan,
I'm afraid there isn't a Debian package for Python2.4+wxPython2.6, so I can't 
test that combination. Our best bet is to go for the GDB stack trace, like so:
	1. Write an iPython script that reproduces the segfault:
		$ ipython <test-script>
		<snip>
		Segmentation fault
	2. Find out where Python lives:
		$ which python
		/usr/bin/python
	2. Find out where iPython lives:
		$ which ipython
		/usr/bin/ipython
	3. Launch gdb:
		$ gdb <path-to-python>
		<snip>
		(gdb) run <path-to-ipython> <test-script>
	4. Get the backtrack:
		Program received signal SIGSEGV, Segmentation fault.
		<snip>
		(gdb) bt
		#0 ...
		#1 ...
		<snip>
		#N ...
Please email me everything that is printed by the "bt" command. You'll 
probably have to copy and paste several screens of backtrace. Thanks!

My guess is that this is because cntr.c is using a python2.3 only
macro, and we haven't sufficiently tested with python2.2. I've been
meaning to drop python2.2 support, but haven't had the time <wink>
PyMODINIT_FUNC
Try replacing all occurrences of that with 
extern "C"
DL_EXPORT(void)
and let us know. Just a guess....

I'm not entirely sure what you mean by this.

Do you want to plot with MPL on top of the FloatCanvas? If so, that will 
be tricky. However, if you want to create another Panel, and plot to 
that, you want to look at the examples and docs for "embedding in wx" 
and similar titles.
By the way, I'm the author of FloatCanvas, so feel free to send me any 
questions, and let me know if you want the latest and greatest version.

yup. If all goes well, you should be able to just use those without 
having to understand them!

There's a page on this topic in the matplotlib cookbook which ought to help 
you get started:

When I do the "python setup.py build" on cygwin I get the following =
error:
Traceback (most recent call last):
 File "setup.py", line 164, in ?
 build_transforms(ext_modules, packages, NUMERIX)
 File "/usr/libpython2.4/site-packages/matplotlib-0.84/setupext.py", =
line 655,
in build_transforms
 add_base_flags(module)
 File "/usr/libpython2.4/site-packages/matplotlib-0.84/setupext.py", =
line 100,
in add_base_flage
 incdirs =3D [os.path.join(p, 'include') for p in basedir[sys, =
platform]
KeyError: 'cygwin'
How do I fix this? I installed numarray and I changed the NUMERIX value =
in the matplotlibrc file from Numeric to numarray but I still have the =
same problem.

I am trying to build matplotlib 0.84 on my Linux box: python 2.2, 
Redhat 3.2.3-53, gcc version 3.2.3 20030502 (Red Hat Linux 3.2.3-53)
The error I got is listed below - I am at a loss as to what is up. I 
have built 0.84 with no problem on my OS X machine.
The point in the code indicated by the error is just after a #if / else 
checking whether Numeric of Numarray is present. I have only Numeric on 
this machine and the error occurs just after the #else indicating 
Numeric is present.
My OS X box has numarray, so I guess this branch of code is not hit 
when I compile there.
I did comment out the py-modules line as suggested in the setup.py 
since I am using python 2.2.
Thanks for any help.

It is packaged *also* for python2.4:
http://packages.debian.org/unstable/python/python2.4-matplotlib

this is in my TODO, I'm testing pydoc for now and there are good possibility to
re-include python-matplotlib-doc

Hi,
I'm appy to learn there is a matplotlib package in sid :)
I have 2 questions (but I'm not sure i'm asking the good person. Are you 
the mainteaner?) :
1) Could you please also package it for python2.4 ?
2) What about the documentation? I know there are problems with pydoc 
(for instance, pyoc need X wich cause problems on the build dd). Maybe 
epydoc could do the job.

Hi all,
matplotlib is now on Debian Unstable:
http://packages.debian.org/unstable/python/python-matplotlib
should work also with Debian Sarge adding this line to /etc/apt/sources.list:
deb http://ftp.it.debian.org/debian/ unstable main
thanks to Marco Presi for upload :)
