Hi,
I'm having some trouble building numpy on a 64-bit Windows 7 machine. I'm
probably accidentally missing a step following the build process described
at
http://scipy.org/Installing_SciPy/Windows; it would be great if someone
could
spot what!
It complains about not being able to find msvcr90.dll. From some googling
that regularly seems to happen for the 64-bit version of MinGW, but not for
the 32-bit version. Is that dll actually present on your system?
Here's what I did:
1. installed python 2.7 from python.org
2. installed mingw32 from the link above (results in gcc 3.4.5)
3. added c:\mingw\bin to front of path
4. ran python setup.py build --compiler=mingw32 install
--prefix=numpy-install
I got the following error:

Can anyone see what I've missed from this?
I'm not sure what the situation is for supporting building with Microsoft
compilers, but on another Windows 7 machine (also 64 bits) with MS
Visual Studio 9.0 installed, the build completes but I get test failures.
You can see the full output of this here:

The few errors due to invalid values are nothing to worry about, although
they should be fixed. In released versions those are not errors but
warnings. It's
