igraph version 0.9.0 has been released! - [http://igraph.rubyforge.org/](http://igraph.rubyforge.org/) IGraph is a Ruby extension for interfacing with igraph ([http://cneurocvs.rmki.kfki.hu/igraph/](http://cneurocvs.rmki.kfki.hu/igraph/) ), a C library for creating and manipulating graphs with a particular emphasis on network analysis functions. IGraph now wraps 99% of igraph functions including functions for randomly and deterministically generating graphs, many functions for analysing the structure of graphs, 2D and 3D graph layout functions and support for reading and writing graphs in various file formats. This release basically completes the wrapping process. Future releases will be for bug fixes and behind the scenes code clean-up. Changes: # 0.9 2007-11-19 - All igraph functions wrapped - Documentation updated with examples - [http://igraph.rubyforge.org/](http://igraph.rubyforge.org/) Alex G.

Yup, I’d not tested on OSX, but I’ll get on it and see if there’s a better way to implement the read/write functions. Until then Gabor’s fix should work (though like he says you won’t be able to use the read/write methods): get the source from svn, remove ext/cIGraph\_file.c, run extconf.rb and make by hand to install.

Une, maybe Alex has a better answer, but it seems that the Ruby igraph extension uses the open\_memstream function, which is not available in OSX. A temporary solution would be to find open\_memstream calls in the code and comment out functions which use it. This way you might lose some exporting functions, maybe all of them.

I’ve released a new gem (0.9.1) which disables the file read/write methods under OSX. This allows the rest of the library to compile and function correctly, but obviously isn’t an ideal solution. In the longer term I’ll look into re-doing those functions so that they don’t use open\_memstream and friends. NB: Under 10.5 running on my PPC Powerbook I had to use: sudo env ARCHFLAGS=‘-arch ppc’ gem install igraph -t – --with-igraph- include=/usr/local/include/igraph/ To get it to install (otherwise it tries to build a universal binary that isn’t compatible with my PPC igraph install), though under 10.4 I don’t think you’ll need that and: sudo gem install igraph -t – --with-igraph-include=/usr/local/include/ igraph/ Should be enough. Let me know if it still gives you problems and I’ll hit it again. Alex G. Bioinformatics Center Kyoto University ---
