[Numpy-discussion] compiling numarrray on Cygwin

[Sebastian Haase]

Hi Duhaime,

are you having a *very* good reason that you want to compile numarray
instead of the newer and better numpy.
Essentially everyone here has switched either from numarray or from
numeric to numpy.
You won't get much help with numarray and problems might not ever get fixed.

However,  people here are very helpful - once you go with the new
numpy - to help converting any old code you might have.   Essentially
numarray and numpy (mostly,  98% ?) Python-code compatible  anyway !!!

Do the the switch and you will get help.

Regards,
Sebastian
