Hi Ricardo,
By default Ubuntu has gcc 4.2, so you shouldn't have gcc 3.4 compilation errors. You could have some missing libraries. How did you install R? And for igraph, did you try to launch R as root then use the following R command:


have you tried to

I discovered a recently pubblicated paper which describes the algorithm I
need (http://arxiv.org/abs/0811.2329) and the author sent me a modified
version of igraph 0.5 source code implementing it. He also sent me a
compiled version for windows.
The windows version works great but I'd like to use GNU/Linux Ubuntu 8.10,
so I tried to compile by myself the source code after installing the R
packages. Here starts my problem because, as I found at the discussion
https://stat.ethz.ch/pipermail/r-help/2008-June/166052.html , the igraph 0.5
version have compile errors with the gcc 3.4 version which I'm using.
I red that version 0.5.1 doesn't have this problem but I need that special
0.5 version.
What do you suggest me to do considering I'm not very able in C/C++ coding?
Thank you,
