Well i am trying to install PyMSSQL-2.0.0b1 and can not achieve this, get strange errors... i have tried some solutions found on Google and StackOverflow but still unable to compile...
please what am i missing ?
( so i have tried :
- to add --compiler=mingw32 after setup.py install build
- to create a distutils.cfd file in Python27\lib\distutils\distutils.cfg with
[build]
compiler=mingw32
and still not working )
(also i'm on Windows 7, and i has need third party libs, must stick to 32 bits version and 2.7)
here are some log with errors :

EDIT : looks like an open issue as related to http://bugs.python.org/issue12641 and the '-mno-cygwin' part (btw if my understanding is ok)
When you install packages for python 2.7 it searches for Visual Studio 2008. All I had to do to fix this is set the VS90COMNTOOLS variable before calling setup.py
If you have Visual Studio 2010 installed, execute
SET VS90COMNTOOLS=%VS100COMNTOOLS%
or with Visual Studio 2012 installed
SET VS90COMNTOOLS=%VS110COMNTOOLS%
Did you install a 32bit or 64bit version of python? Please try to install a 32bit version.
Did you already try to compile with compiler shipped with Visual Studio instead of MingW32? (The file "vcvarsall.bat" initializes the environment of VS)
(Express Versions of Visual Studio are free)
Try using a MinGW version with GCC 4.5.2.
This version supports the -mno-cygwin option and should build correctly.
Using this version I successfully built PyMSSQL-2.0.0b1 on Windows 7 64-bit with Python 2.7 32-bit.
I did not modify the source tarball. I just ran the following command in the source directory: python setup.py build --compiler=mingw32. I have C:\MinGW\bin in my PATH.
Note: I was missing Cython, so I downloaded the latest version and built it using MinGW as well. I did this by running python setup.py build --compiler=mingw32. The only other dependency I was missing was the iconv library and I built it inside MinGW using these directions.
I think you have wrong version for you bit.
