Re: [igraph] problem installing igraph 0.3.2

[Gabor Csardi]

Hmmm, this works for me for all version i've tried:
http://sourceforge.net/projects/igraph/
http://cneurocvs.rmki.kfki.hu/igraph/#downl
http://cran.r-project.org/src/contrib/Descriptions/igraph.html

Tamas is right, R does not pass '-shared' to g++ when trying to make a
library, this is strange. There is a thread about the same error here:
http://tolstoy.newcastle.edu.au/R/help/05/09/11479.html
Unfortunately it does not lead very far....
I've tried it with older R versions (2.0.1) and older gcc, g++ versions
(2.95.4) and it works with these as well.

Dominik, can you tell me something about your system, both the Linux and the
R parts? Thanks.

You could also try to build other packages which contains C and/or C++
sources just to see whether the problem is igraph specific. Thanks again.
