I am trying to install matplotlib on Cygwin but at the installation I get an error:
0 [main] python2.7 2968 child_info_fork::abort: address space needed by 'cygEGL-1.dll' (0x420000) is already occupied
I already tried to kill all the processes, reboot my PC and rebaseall. It does not help.
Here is the complete log:
$ python setup.py install

What can I do next ?
Your problem may possibly come from the backends configuration. I recommend you to disable every backend from setup.py but windowing that allows you to plot using the Wx backend. The libraries are available on Cygwin. You should have no need for Gtk or Tk.
