[Numpy-discussion] compiling numarrray on Cygwin

[Duhaime Johanne]

I have problem to install numarray on cygwin. I have seen emails on that
topic but I finally do not have a solution. 
 
Below is the error message for numarray-1.5.2 on python 2.4.3.  I am
using numarray instead of numpy because I need the module to be
compatible with a software : MAT (Model-based Analysis of Tiling-array).

 
I have seen some solutions but I do not know exactly how to do since I
am not familiar with python and cygwin. Someone suggests to disable the
package that contains fetestexcept and fetestexcept. I do not know if
this is important for my software but I am willing to try. The problem
is that I do not know how to disable this package... 

The same person mention that it would put a "solution" in the csv
repository. If I am right there is no csv repository for numarray.
Should I look to the python csv. In fact I did that, but have not seen
any comment related to my problem. 

As you can see my questions are very basic. Sorry about that. But I
would really appreciate help to solve that problem. Thank you in
advance for any help.
