Re: [igraph] building R package from development branch igraph--main--0.4

[Vincent Matossian]

  Gabor, I just recently checked out and compiled the 0.4 and was really excited to see the amazing collection of community detection algorithms and other features added !

I ran a few community algorithms, walktrap,
edge.betweenness., fastgreedy on a ~150k collaboration network, fastgreedy successfully completed on a simplified connected graph but failed on the nonsimplified version with what appeared to be a memory access violation. Other algorithms also lead to early program termination with either R crashing or the memory access violation notice. I tried running a 30k node BA graph with m=3 and noticed these problems with a few algorithms (below 20k nodes and 60k edges it worked just fine on my machine).

For reference to other windows users, I was able to compile the development branch of igraph and R interface source on windows/cygwin, but arch appears to have problems with long path names due to a limitation of the windows shell to around 250 characters. I don't know why but when untaring the file (transferred from a linux box) if I use the verbose flag the source uncompresses and compiles fine, without the verbose flag the decompression fails and claims that filenames are too long (?!?)...

I realize that this is very preliminary feedback I hope to have more constructive things to say soon,

Thanks!

  Vincent

Vincent, just realized that there is also an automatic
R windows binary package building facility:
http://129.217.207.166/
So if that works for you then it is not required to install all the
R building tools.

But please make sure that you replace the Maintainer field in the
DESCRIPTION file of the source package to your email address,
otherwise the result of the build will be sent to me. :)

Also, i don't know how it works if the package is semi-broken, eg.
some documentation is missing from the development version, etc.

G.
