Cygwin and matplotlib

Community matplotlib-users

Could someone please kindly let me know if matplotlib is compatible with Cygwin? I installed all the necessary dependencies, yet I cannot get matplotlib to compile correctly. At the build step, this is what I get:

$ python setup.py build
basedirlist is: [’/usr/local’, ‘/usr’]

Matplotlib works well with Cygwin (I am using it with the gtkcairo backend), but installing it can be a hassle. You’ll have to fix errors such as the ones you’re seeing by modifying setup.py or setupext.py.

Would anyone be so kind as to show me how to modify setupext.py such that the install actually works? I’m surprised this hasn’t come up already, actually, as there definitely are a lot of bugs in trying to set it up now.

At the very list, it seems that ConfigParser is constructing an empty list, and the matplotlib setup hasn’t caught that error. If anyone who has successfully built on Cygwin could kindly send me their modified setupext.py and also what packages they have installed, that’d be greatly appreciated.
