[Numpy-discussion] building ATLAS on Win32 - endless compile loop

[Bill B. <wb...@gm...>]

Trying to compile Atlas from source on Win32 with Cygwin.  Anyone seen 'make
install' for ATLAS go into and endless loop before?

More info:
Following the instructions here:
   Installing SciPy/Windows -
SciPy.org<http://www.scipy.org/Installing_SciPy/Windows?highlight=%28%28----%28-%2A%29%28%5Cr%29%3F%5Cn%29%28.%2A%29CategoryInstallation%5Cb%29>
At this step:
    "5) As prompted by the config script, execute
 make install arch=YOUR_ARCHITECTURE  and wait for approx > 15min."

It was taking much longer than 15 minutes, but I figured my laptop is just
slow or something.
So I left it on when I went to bed.  It was still cranking away 6 hours
later when I got up.

Just thought I'd check if anyone had seen that before.

My laptop is a Pentium M, which isn't one of the options on the architecture
list.  So I picked "unknown".

In that case ATLAS propably does a full search instead of the much
smaller architectural default one. This takes much longer, but not
infinitely.

I did some searching on the web and found that Pentium M is more or less a
Pentium III.
After selecting "Pentium III" in the ATLAS setup, the build worked.  Still,
on my ~1GHz laptop took several hours, nothing like the 15 minutes
advertised on the Wiki.   (I updated the wiki accordingly)

Just out of curiostiy what processor is the official Numpy win32
distribution built for?  Or does it just not use optimized blas/lapack?
