Problem installing pyamg on windows 7 64-bit

[Oren Livne]

Dear All,

I am trying to install pyamg. I am using windows 7 64b-ti, python
2.7.2, numpy 1.6.1, scipy 0.10.0, nose. When I run

python setup.py install

it dies on the following error:

Sorry, there was more one output line:

error: Unable to find vcvarsall.bat

Hi Oren,

Any luck installing in Windows? I mostly use Mac and Linux, and
installing PyAMG after Scipy/Numpy usually goes OK in these
environments. You could try compiling in Cygwin (never done it, but
it's supposed to be a full featured Linux environment under Windows).

I did a little Googling though, and it looks like your problem is a
common one when interfacing Microsoft compilers, Swig and Python.
These posts might be helpful,
