Compile python extensions under windows/cygwin

[Joana]

I mantain Python on Windows, all installed packages are under c:
\Python25\Lib\site-packages. Now I have to build C libraries used by
python extensions and I am using cygwin, but I don't know how to
install the module in Windows directory.

Can anyone help me?

Thanks in advance

Are you sure you want to use Cygwin? Binaries build with and for Cygwin
are not compatible with ordinary Windows binaries. I assume that you
want to build C extensions with the open source MinGW32 compiler? That's
easy:

* Install MinGW32
* Add its bin directory to PATH
* Add a file distutils.cfg in C:\Python25\Lib\distutils with
  this content:

[build]
compiler=mingw32

* Have fun

hmm.. but the problem with mingw32 is that it does not have the
libraries I need. The module I want to install includes netinet/in.h.
So the answer is that I can't install that module in Windows?

I think it is a problem because as far as I know cygwin cannot
see files outside of /cygwin.

Where is python installed in cygwin?

Can't you install the same packages into cygwin?

and then do your building in there...?

I think I don't understand this comment.

All the drives on my windows machine are visible using the scheme:

/cygdrive/<drivename>/<path>/<to>/<file>

For example:

bash-3.2$ ls -l /cygdrive/c/windows/system32/drivers/etc/hosts
-rwx------+ 1 johnbre mkgroup-l-d 820 Nov 8 2008 /cygdrive/c/windows/
system32/drivers/etc/hosts
bash-3.2$

and you can mount things in cygwin as you choose:

The answer to the problem of compiling python packages was:

* Download Visual C++ 2008 Express for free from Microsoft.
* Find it was incompatible with compiling packages for my Python 2.5
(Visual Studio 2003).
* Move to Python 2.6.
* Problem solved, things compiled and worked

I have used MingW to do this. Might this help:
