Hi.
I'm pleased to announce version 1.0 of graph-tool. This version contains many new features, improvements and bug fixes. In fact, previous versions (0.9 namely) are considered deprecated, and should be avoided. ;-) From now on, hopefully, there should be no more radical changes on how things work between versions, and improvements should be more incremental.
Notable changes ===============
A lot of things changed since the 0.9 version, including how certain options work, and lots of new stuff have been added. For a full list of modifications, see
https://projects.forked.de/graph-tool/log/?action=stop_on_copy&rev=69&am...
The most important new features are:
* Community detection support * Extended clustering coefficient * Line graph generation * Minimum spanning tree * Sampled distance statistics
Also the documentation on the website has been massively updated and reorganized. Check it out at:
https://projects.forked.de/graph-tool/wiki/GraphToolGuide
Download ========
Download information is available on the website:
https://projects.forked.de/graph-tool/wiki/GraphToolDownload
Enjoy!
Ps. graph-tool has now support for bash command line completion! For how to enable it, please read http://furius.ca/optcomplete/. I'll post later some more specific instructions on the wiki.

OK, I'll try it out, tomorrow I'm gonna buy two more gigs of RAM anyway.
Regarding the GraphML reader: Do you think it would make programs faster to remove this wrapper interface with any and make the reader a template for MutableGraphs?

Not much, I think, since most of the function-calling overhead would be from the expat hook functions anyway. But the idea of the wrapper is to separate the part that depends from the expat library from the rest, so it can be compiled separately as a library (like the graphviz reader).
If you're curious you can do some profiling and see how much time it actually spends with the wrapper...

Did it - make; make install.
Now I get:
$ graph-tool Traceback (most recent call last): File "/usr/local/bin/graph-tool", line 22, in ? from libgraph_tool import * ImportError: No module named libgraph_tool
What do I have to do?

Well, if you did "make install" the libgraph_tool.so module should have been installed, by default, in a place where python could find it, and everything should have worked... Are you sure the prefix you used for the installation is the same where python is installed, and that the place where libgraph_tool.so ended up is known to the python interpreter (via the PYTHONPATH variable)?
In any case, if you don't want to install it all, you can just put both graph-tool and libgraph_tool.so (found in src/graph/.libs after compilation) in the same directory, and it should work.

Yeah, this finds the library at least:
$ PYTHONPATH=/usr/local/lib/python2.4/site-packages/ graph-tool Traceback (most recent call last): File "/usr/local/bin/graph-tool", line 22, in ? from libgraph_tool import * ImportError: /usr/local/lib/python2.4/site-packages/libgraph_tool.so: undefined symbol: _ZN5boost6python3apineERKNS1_6objectES4_
Of course, the graph-tool file and the libs are both from the same build ...
Compiler is still $ g++ --version g++ (GCC) 4.1.1 (Gentoo 4.1.1-r3) on Gentoo amd64, Boost is Gentoo packages 1.33.1-r1

Strange... How about boost python? Was it also compiled with the same GCC version?
I'll look at your other problem with the reader soon, I'm a bit out of time at the moment.

I should think so, gcc 4.1.1 is my system compiler ...
I'm not at home right now, so I can't look at the files right now.
But I'll try to find out if there's a hint in the .so's as to with which gcc they've been built.

Thanks! Maybe you can send me a GraphML files of yours, it might again be some issue with the format of my files ...

I had a bit of a Boost version chaos here, had a locally modified copy of the headers in /usr/local/include and other binary libs in /usr/local/lib64 ...
Now recompiling, I think it should work ...
