Yes that was the bug.
Please commit the fix.

Revision 7985 contains a typo (see bug tracker). Try replace the string 
PY_ARRAYAUNIQUE_SYMBOL with PY_ARRAY_UNIQUE_SYMBOL in setupext.py.

Hi,
I'm trying to compile numpy/scipy and matplotlib (I did it N times 
without any problem).
Numpy and scipy are ok (.test() is fine).
However, from pylab import * fails with way:
/usr/local/lib/python2.6/dist-packages/pylab.py in <module>()
----> 1
 2
 3 from matplotlib.pylab import *
 4 import matplotlib.pylab
 5 __doc__ = matplotlib.pylab.__doc__
/usr/local/lib/python2.6/dist-packages/matplotlib/pylab.py in <module>()
 204 silent_list, iterable, dedent
 205
--> 206 from matplotlib import mpl # pulls in most modules
 207
 208 from matplotlib.dates import date2num, num2date,\
/usr/local/lib/python2.6/dist-packages/matplotlib/mpl.py in <module>()
----> 1
 2
 3 from matplotlib import artist
 4 from matplotlib import axis
 5 from matplotlib import axes
 6 from matplotlib import cbook
 7 from matplotlib import collections
/usr/local/lib/python2.6/dist-packages/matplotlib/artist.py in <module>()
 4 import matplotlib.cbook as cbook
 5 from matplotlib import docstring
----> 6 from transforms import Bbox, IdentityTransform, TransformedBbox, 
TransformedPath
 7 from path import Path
 8
/usr/local/lib/python2.6/dist-packages/matplotlib/transforms.py in 
<module>()
 32 import numpy as np
 33 from numpy import ma
---> 34 from matplotlib._path import affine_transform
 35 from numpy.linalg import inv
 36
ImportError: /usr/local/lib/python2.6/dist-packages/matplotlib/_path.so: 
undefined symbol: PyArray_API
I may have a problem with the svn update but I'm not quite sure.
Maybe it is just a temporary compatibility problem in between matplotlib 
and numpy.
Can someone comment on that?
I'm using:
numpy At revision 7773.
scipy At revision 6120.
matplotlib At revision 7985.

Hi,
just wanted to raise this problem on the devel list, where it probably
belongs. Also, if nobody has time to look at it now and you prefer me to
file a bug, please don't hesitate to tell it.
the original post is there:

FWIW: It comes from a set of OpenSolaris patches to Python here:

Looking at it, it describes itself as a script for running the C/C++ 
compiler when building python modules.

What is /usr/lib/python2.4/pycc? Some sort of wrapper around the 
compiler? I don't have it on my Sun machine. I would start by looking 
at that to see what it's doing. It may not be passing the source file 
along to the compiler.

matplotlib is probably not finding pygtk at build time -- you need
have pkg-config installed, and locate your pygtk-2.0.pc file and then
add that path to your PKG_CONFIG_PATH. You can check the output of
the build script at the beginning in the section
OPTIONAL BACKEND DEPENDENCIES
 libpng: 1.2.27
 Tkinter: Tkinter: 50704, Tk: 8.4, Tcl: 8.4
 wxPython: 2.8.8.0

 Gtk+: gtk+: 2.14.4, glib: 2.18.2, pygtk: 2.13.0,
 pygobject: 2.15.3
 Mac OS X native: no
 Qt: Qt: 3.3.8, PyQt: 3.17.4
 Qt4: Qt: 4.4.3, PyQt4: 4.4.4
 Cairo: 1.4.12
You need to have an entry for Gtk or else the backend will not be built.

If you have access to svn, you can do:
svn co https://matplotlib.svn.sourceforge.net/svnroot/matplotlib/trunk/matplotlib
mpl90.1 -r3352
If not, I can upload a tarball somewhere.

Use "text" or "annotate", eg

There may be a limitation on window sizes in the various GUI backends. 
Have you tried using the non-GUI backend (agg), and now "show"ing it, 
but just using "savefig"?

Hi,
I'm new with matplotlib and
I'm trying to embed matplotlib objects into pygtk.
I tried different backend imports (GTKAgg, GTK, GTKCairo) and always 
get the same error (attached below) referring to the missing 
_backend_gdk package.
I work with MAC os x 10.6, python 2.6, pygtk2, matplotlib 0.99.1.1, 
all installed via macports , even though I tried to install matplotlib 
from source via the setup.py script and I get exactely the same problem.
Could you help?
Many thans in advance,
Federico

I'm trying to make a 10 inch wide by 30 inch high, 72 dpi figure and
display it interactively. Matplotlib seems to squash the height for
anything over a certain size, depending on the backend:
---------------------------------------------------
#!/usr/bin/env python
import sys, os, matplotlib
matplotlib.use('TkAgg')
import matplotlib.pyplot as plt
print os.uname()
print sys.version
print matplotlib.__version__
print
f = plt.figure(figsize=(10,30), dpi=72)
print "figheight before show(): %f" % f.get_figheight()
plt.show()
print "figheight after show(): %f" % f.get_figheight()
--------------------------------------------------
Prints this:

==========================
Tk squashes heights over 12 inches (the heights do get larger as you
request larger figures, but not as large as what you request); GTK
goes up to 11; and Qt4Agg only goes up to 7.3. WX seems to be the
only backend that will give me a 30 inch figure, but even then I have
to manually resize the window to make it fit. This happens in scripts
with pyplot, in ipython with or without -pylab, and via the matplotlib
API.
Is there some limitation on figure sizes?

I ended up implementing this myself, it wasn't too hard. I've attached
the code if anyone else is interested. I don't know matplotlib that
well, so I don't know if there's much duplication of code in there.
I thought I'd CC the dev list in case others think it might be useful.
If not, sorry for the noise.
Cheers,
Jason
