compilation failure in Debian testing with python 2.7

[barak]

Running this in Debian testing, with python 2.7, and all the packages that seem needed (see git://github.com/barak/pyfauxfur README.md for package list) running the program pops up a window, but clicking the RUN button gets a compilation error. See below for details. Naturally, I have no clue what is going wrong.

$ ./PyFauxFur.py
Generating texture with the following parameters :
-r -s 0.0005 -a 0.25 -b 0.0625 -d 12.0 -x 400 -y 400

Sorry, I don't have time to work on this package anymore (it was originally a test assignment and I never picked it up again afterwards), but based on the stack trace you provide, it seems to be an issue deep inside scipy, not an issue in my code.

You should probably ask the scipy maintainers if they know about this problem.

You can add a "verbose" parameter to weave.inline (see http://docs.scipy.org/doc/scipy/reference/generated/scipy.weave.inline.html) to add more logs of the compilation process, look at the generated C file, and eventually know why the "end" symbol is defined twice.
