Re: [igraph] python 2.5 installer for igraph 5.2?

[Chris Wj]

I think google code allows you to post automated uploads. I work with a C++ library called Ultimate++ and they use a nightly build technique to upload to google code. See here: http://code.google.com/p/upp-mirror/downloads/list and search the forum for some conversations on thier build process http://www.ultimatepp.org/forum (I'll try to identify the exact process too). 

U++ uses a remote build system, although I think it was created for the project itself. I'll do some more research on this. 

I think you should reach out to the community a bit here for some help. If you set up a VMware server and give package/build maintainers access to individual servers, then you don't have to do all the leg work. Or you can have branches of the build system on launchpad that can help with any platform-specific changes that need to be made. However you choose to do it, involving some skilled members of the community may also be a chance to get more eyes on the core implementation of igraph to help submit patches instead of just unofficial bug reports.

I am actually setting up such a build server right now using VMWare
Server. It is not completely trivial, because I need to write the
scripts for myself: pulling from bzr if there is something new,
compile this and that, build docs, etc. and then copy the packages to
a web-server.

Even just publishing the packages is not trivial, since most free
development sites (sourceforge, launchpad, etc.) don't support
automated uploads. savannah.gnu.org might work, but they refresh their
mirrors very slowly, maybe once a day, and that is not optimal if you
want to do nightly builds.

So it is a pain in the neck. If you are aware of some ready-to-use
solution to make automated builds for different platforms, please tell
me.
