I have a proposed fix in branch fix-gdk-strides of
https://github.com/jkseppan/matplotlib.git
but I don't seem to have any systems with the prerequisites to compiling
the gdk backend. Could someone who uses that backend try this out? It
seems that drawing images or mathtext would exercise the code.

I think there's clearly a bug in that review request. Does
_backend_gdk.c not get compiled in tests?

Looks like this is an incompatibility between Tcl/Tk 8.5.11 and MacOS 
10.9. Tcl/Tk 8.5.15 does not show the problem. Time to try to build 
8.5.17rc1 from source, I guess.

Please try with commit 7f71233d55683b1c1bda1b365b61f912f8a154df
What version of numpy are you using, we only support 1.6+

What OS and what branch are you using?
Can you roll back to one commit before the most recent merge?
https://github.com/matplotlib/matplotlib/pull/3547 updated the numpy
api. If that fixes it, please make a new issue on github reporting
the problem.

Hi all,
I cannot build matplotlib from git
src/_backend_gdk.c: In function ‘pixbuf_get_pixels_array’:
src/_backend_gdk.c:43:10: error: ‘PyArrayObject’ has no member named
‘strides’
src/_backend_gdk.c:46:10: error: ‘PyArrayObject’ has no member named ‘base’
error: command '/usr/bin/gcc' failed with exit status 1

Have you tried using pillow? https://pypi.python.org/pypi/Pillow/2.6.1
It might just a drop in replacement, but that depends on how bluemarble 
uses PIL.

Tom,
I believe the "pillow" package is the actively maintained fork of PIL.
Could be wrong on that though.

To matplotlib-users,
basemap bluemarble() requires PIL, which is not available for Python3.
What is the usual workaround, when using Python and wanting to do
bluemarble()?
Thanks,
Tommy

To matplotlib-users,
I ran the installation guide here on Mac OS:
http://matplotlib.org/basemap/users/installing.html
Except I did brew install geos and subsequently did:
export DYLD_LIBRARY_PATH=/Users/tc9/homebrew/lib
export GEOS_LIBRARY_PATH=/Users/tc9/homebrew/Cellar/geos/3.4.2
export GEOS_DIR=/Users/tc9/homebrew/Cellar/geos/3.4.2
And instead of python setup.py install I did:
/usr/local/bin/python3 setup.py install --user
I got this warning:
/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/distutils/dist.py:260:
UserWarning: Unknown distribution option: 'namespace_packages'
 warnings.warn(msg)
When I try to run simpletest.py in the folder examples with
/usr/local/bin/python3 I get this error:
Assertion failed: (0), function query, file AbstractSTRtree.cpp, line 285.
Abort trap: 6
What am I doing wrong?
Thanks,
Tommy
