Python Compile Dev Build on Windows

Question

Reproduction Steps

I'm trying to build the development version of Pandas on a Windows 7 machine with Python 2.7.6. I followed the steps here ( http://pandas.pydata.org/pandas-docs/dev/install.html ).

1. I checked that I had the needed dependencies and some of the optional ones as well (Cython=.20, Numpy=1.7.1, Python-DateUtil=1.5, pytz=2013.9)
2. I double checked the dependencies were up to date
3. I cloned the github with: git clone git://github.com/pydata/pandas.git
4. I installed the minGW compiler suite (including C and C++ compilers)
5. The mingw setup is version 4.3.3

6. I made sure that the pydistutils.cfg is in the correct location (C:\\Python27\\Lib\\distutils) and has the following code:

    [build] compiler=mingw32 

7. I attempt to build using: python setup.py build --compiler==mingw32
8. This begins to build for a few seconds, then runs into the below error

Error

How can I fix this so it builds? Thanks!

Answer 1

Just in case someone made the same mistake as me, I realized I'm using a 64-bit Windows 7 with only a 32-bit MinGW compiler. There's a MinGW 64 bit compiler here that fixed this issue.
