Subject: [Rd] swig 1.3.35 & R - is the R wrapper still maintained and
	of	interest?
Message-ID: <1208515782.11561.27.camel@localhost>

Dear all,

I was trying to use the R swig wrapper with R 2.7 and shogun
( http://www.shogun-toolbox.org ) but it fails completely, as in doesn't
even compile and even after patching then though compiling - crashes...

So I asked on swig-users/swig-devel CC'ing the potential R maintainer
but I never received a reply. I now wonder if anyone here could help or
would be willing to maintain R+swig.

The compile fix for R 2.7 is here

http://article.gmane.org/gmane.comp.programming.swig/12697

and the crash I am now that it compiles see is

To reproduce

?wget http://nn7.de/debugging/shogun-0.6.1+svn2882.tar.bz2
tar xjf shogun-0.6.1+svn2882.tar.bz2
cd shogun-0.6.1+svn2882/src
./configure --interface=R-modular
make

(wait a few minutes)

R
dyn.load('features/Features.so')
#source("features/Features.R") # not even necessary.

Note that shogun works for both python and octave nicely...

?So the question for me is, will this be better maintained in the future
or should I stop investing time on getting R supported?

Desperate,
Soeren
