[pygtk] compiling pygtk on win32...

Before everything else, if you're using Python 2.6.3 on windows to  
compile python extensions with mingw32, you'll need to patch  
distutils. See http://bugs.python.org/issue7131 for more details.

First, you need to make sure you have the required packages installed  
for GTK+ and dependencies. See [1] for the list I have used.
Add the directory you used for your GTK+ installation to the windows  
PATH environment. Mine looks like  
'/d/Progra~1/gtk-bundle/2.16.6-20090911'. Then you install pycairo,  
pygobject, pygtk, etc. Those development files you mention are  
included in the installers of pycairo, pygobject, pygtk, etc (they get  
installed into /path/to/Python26/).

Then, you need to make sure your PKG_CONFIG_PATH environment variable  
is set correctly before executing your build (within msys). Mine looks  
like  
'/d/Progra~1/gtk-bundle/2.16.6-20090911:/d/Progra~1/Python26/Lib/pkgconfig'  
(within msys, windows itself uses ';' as a seperator, msys uses ':').  
If everything is installed correctly and the PKG_CONFIG_PATH  
environment variable is set correctly the command (within msys)  
'pkg-config --list-all | wc -l' should return 43 lines. Run as  
'pkg-config --list-all' to see a detailed list.

With all that, your good to start compiling...

No. Just having them installed should be enough. But if you insist on  
compiling, you'll need to build pycairo, pygobject, pygtk in that  
order. Then it doesn't matter if you start with pygoocanvas or  
pygtksourceview [2] or something else. Just respect the packages'  
dependencies.

On windows, the recommended way to compile pycairo/pygobject/pygtk/etc  
are the setup.py files included with the packages' sources. See [3]  
for more details. Note that currently, the windows build system is in  
need of some love.

Eerm, the binary releases on ftp.gnome.org are built by people who  
have been doing this for years (thanks to everybody involved in  
this!), are generally tested by the same people and are in use by a  
lot of people. This means those releases receive a whole lot of  
testing. And the binary releases are supported (if you encounter a bug  
you can complain to bugs.gnome.org).

You're basically on your own when you compile your own snapshots.

That being said, i've been compiling my own _snapshots_ of the  
following for python 2.6:
pycairo-1.8.8 (patched, upstream refuses to support mingw32),
pygobject-2.21.0 (following git master, patches by John Stowers, extra  
patches by myself),
pygtk-2.16.0 (following git master, patches by John Stowers, extra  
patches by myself),
pygoocanvas-0.14.2 (custom setup.py)
pygtksourceview-2.8.1 (fixed setup.py, needs a recompiled  
gtksourceview snapshot, see [2] for details).

These do not contain gtk-doc documentation (on my todo list) and have  
to be installed in the order listed above. If you test these, unintall  
all previous versions first! You can find those snapshots here:

Hope I haven't forgotten anything,
Have fun,
Dieter

[2] You'll need to recompile gtksourceview before you can start  
compiling pygtksourceview. This because the current gtksourceview  
version on ftp.gnome.org links to libxml-2.dll, but  
libxml2-2.7.4-1_win32.zip only contains libxml-2.0.dll.
Not doing this will result in a succesfull pygtksourceview build, but  
you'll experience all sort of pain at runtime: 'import gtksourceview'  
will work, 'import gtk; import gtksourceview' will fail with an  
obscure memory error.
