matplotlib-users Mailing List for matplotlib (Page 2)

I am trying to compile MPL on Snow Leopard without success.  I have a
fairly fresh system (10.6.2) with python.org 2.6.4 installed.  I have
downloaded the MPL trunk with svn.  I had to make a small change to
the make.osx file because there are some extra ".  However I still
can't get MPL to compile/install; it fails when compiling zlib.  The
change I made in the make.osx file is on line 11.  It used to be:

ARCH_FLAGS="-arch i386 -arch ppc -arch x86_64"

and is now:

ARCH_FLAGS=-arch i386 -arch ppc -arch x86_64

The error I get while compiling is copied below.  Can anyone help me
figure out what is wrong?

Thanks,
Jeremy

All,

I'm using Aptana (Eclipse) and pydev on a macbook pro. I'm trying to work with the following:

http://matplotlib.sourceforge.net/examples/user_interfaces/fourier_demo_wx.html

Now, this is a fairly complicated and interconnected piece of coding. When I am trying to learn something, I like to break it down into smaller chunks and test, which is much better than trying to type in the whole program (yes, I know I can copy and paste, but working a piece at a time is the best way for me to learn).

So, can anyone recommend how to test the Param class by itself, then the SliderGroup class, etc, then put all the pieces together?

Suggestions at how others work this idea would be very helpful.

David.
