Compile IP2Location Python extension for Windows 7

Question

I want to compile / install the IP2Location Python extension found here:

www.ip2location.com/python.aspx

I tried following the instructions at these sites:

eli.thegreenplace.net/2008/06/28/compiling-python-extensions-with-distutils-and-mingw/ boodebr.org/main/python/build-windows-extensions

But I am getting no where. The problem is the Python extension relies on another C library:

www.ip2location.com/c.aspx

When I try to compile this library in cygwin I get the following output:

make  all-recursive
make[1]: Entering directory `/home/ty/Python-IP2Location/C-IP2Location-3.0.0'
Making all in libIP2Location

I'm running python 2.6.3 on Windows 7 32-bit. I have MS Visual Studio 2008 (though no idea how to use it) and of course cygwin / MinGW.

Any help or pointers would be greatly appreciated.

Answer 1

Try adding -lws2_32 option to linking command.

BTW, there is another pure Python library to get country from IP.

Answer 2

OK, so the full solution is:

1. download stdint.h and put it in the IP2Location C Library folder: http://msinttypes.googlecode.com/svn/trunk/stdint.h
2. open a dos prompt and execute "C:\Program Files\Microsoft Visual Studio 9.0\VC\vcvarsall.bat"
3. from the same dos prompt execute "nmake /f Makefile.win"
4. cd to the Python extension folder and execute "set LINK=/nod:msvcrt.lib"
5. lastly do the standard "python setup.py install"

The credit for the "set LINK=/nod:msvcrt.lib" advice goes to Tim Roberts of Providenza & Boekelheide, Inc (probo.com). -- he was kind enough to answer my cry for help on the python win32 mailing list. Thanks Tim!
