Hi,Note that you don't need sysadmin permissions to upgrade. You can set up a Python virtual environment inside your home directory using python-virtualenv, compile and install igraph locally into your home directory and then use that. A few tweaks are required, though, the whole process is roughly as follows:
1. Get the igraph source code2. Configure it using ./configure --prefix=/home/marco (or wherever your home directory is) 3. make && make install (it will put the necessary files in /home/ marco/include and /home/marco/lib) 4. Set up your library path to include /home/marco/lib (otherwise Fedora won't find the igraph libs): export LD_LIBRARY_PATH=/home/marco/ lib 5. Create a Python virtual environment (see, e.g., http://peak.telecommunity.com/DevCenter/EasyInstall#creating-a-virtual-python ) 6. Make sure that "python" points to your virtual environment (i.e., type "which python" in your shell and check the path). 7. Install easy_install into your virtual environment using http://peak.telecommunity.com/dist/ez_setup.py .
8. easy_install python-igraph into your virtual environmentNote that the changes in step #4 should be done whenever you plan to use the locally installed igraph (that's in your home directory). Your best bet is probably to add it to your .profile or .bashrc.

Hello all igraphers! I am using an old version of the library on an old Fedora machine. When I build a tree, using: g=igraph.Graph.Tree(100,3) and then write the graph to a file (GML format) the result is a directed graph: the GML file reads: Creator "igraph version 0.5 Fri Jun 26 12:31:25 2009" Version 1 graph [ directed 1 .... Which is not obvious, since the Tree() should default to "type=TREE_UNDIRECTED". Is that a glitch in the old version I am using, or it's a bug? And if it is the latter, has it been fixed in more recent versions? Is there a fix without updating? I guess I should update, but I don't know if the admin will let me :) Thanks, marco -- restituiremo il riso ai salici _______________________________________________ igraph-help mailing list address@hidden http://lists.nongnu.org/mailman/listinfo/igraph-help
