Requirements

ctypesgen is available via svn http://code.google.com/p/ctypesgen/source/checkout or as a tarball from http://pypi.python.org/pypi/ctypesgen

Only 2 requirements:

Python, at least version 2.4
A C pre-compiler, if you have a C compiler installed such as GCC you already have one

Windows

Windows does not ship a compiler/pre-processor with the operating system so one needs to be installed. For example, http://www.mingw.org

Assuming mingw32 has been installed in the default location, open a command prompt and issue:

path %SystemDrive%\MinGW\bin;%PATH%
ctypesgen.py -a -l MYLIB - o pyMYLIB.py MYLIB.h

Where MYLIB.dll is the name of the name of the dll of interest and MYLIB.h is the main header include file.

NOTE the "-a" flag, this ensures macros etc. that are present in include files that MYLIB.h include are included in pyMYLIB.py.

Alternatively gcc does not need to be in the path:

ctypesgen.py -a --cpp="%SystemDrive%\MinGW\bin\gcc.exe -E" -l MYLIB - o pyMYLIB.py MYLIB.h

The --cpp flag could also be used to call the Microsoft Visual Studio compiler cl.exe.

C Pre Processors

gnu gcc is known to work.

Microsoft Visual C++ VS .net 2003 is known to fail. Should be able to setup path with:

REM VS C++ 6.0
call "C:\Program Files\DevStudio\VC\bin\VCVARS32.BAT"

REM VS C++ .NET 2003
call "C:\Program Files\Microsoft Visual Studio\VC98\Bin\VCVARS32.BAT"

Then use --cpp="cl -E" or --cpp="cl -EP"

Pure Python processor would be a nice addition but at the moment there does not appear to be one, possible research items:

See HackingTips for modifying ctypesgen and testing information.
