Under Laurent's advice I stopped using Windows for Rpy2 and took days to install Ubuntu Lucid correctly under VMWare exclusively so I could use Rpy2 2.1.4 and R in a project I am working on. I am a complete newbie to Linux and just an apprentice to Python but have 30 years experience with other computing systems.
I followed the instructions exactly although it was not clear if I could install R binaries (and save time) or if I had to compile with the --enable-R-shlib switch. Just to make sure I did the latter and eventually it installed without error. After this I installed Rpy2 2.1.4 and it also installed without error. I can do import rpy2 but import rpy2.robjects or import rpy2.rinterface gives the error ImportError: libR.so: cannot open shared object file: No such file or directory I had a look around the web and found this post that seems to describe the same error. http://bitbucket.org/lgautier/rpy2/issue/30/rpy2-210beta2-ubuntu-karmic-librso-not I can also do R RHOME and it comes up with /usr/local/lib/R In the post above he says: "I was able to fix the problem by creating a link to libR.so in /usr/local/lib, as suggested in the FAQ" Ah this looks promising but as a newbie to Linux I have no idea how to do this. In the FAQ it says "make a link to R_HOME/bin/libR.so in /usr/local/lib, or in some other location that your system knows as a standard place for libraries; then run 'ldconfig' as root; " which is no more help to a Linux newbie. I figure I have to obviously let Linux to understand the link to LibR.so, which is in /usr/local/lib/R/lib ... Aug 2010 and /usr/lib/R/lib ... Jan 2010 but I do not understand how to carry out the above task. I guess this must be very easy since exact directions are not given but none of the various things I have tried have worked. All help and comments appreciated. ------------------------------------------------------------------------------ This SF.net email is sponsored by Make an app they can't live without Enter the BlackBerry Developer Challenge http://p.sf.net/sfu/RIM-dev2dev _______________________________________________ rpy-list mailing list rpy-list@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/rpy-list
