My package manager reports the following versions: gcc 4:4.3.1-1ubuntu2 and g++ 4:4.3.1-ubuntu2. I can't remember exactly the output of compilation because I resolved my problem in another way but it was very similar, at least in the last lines, to the one posted in the link in my previous message. My solution was to find the differences between the original 0.5 version of igraph and the modified 0.5 version containing the algorithm I'm interested in and patching the current 0.5.1 version. The compilation, after this risky operation, worked well and now I can use apparently without problems both the 0.5.1 version and the algorithm. So, if you agree, I'll close here this thread. Otherwise I can try to recompile my 0.5 modified version (or the original one) to get insight the problem.

Thank you,

Btw. Ubuntu 8.10 does not have g++ 3.4 as far as I know...

  I'm trying to make some social network analyis (in particular community

use R with igraph.
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,
