[R] Installing RXlisp

[Luca Scrucca]

Dear R users,

I was trying to install the package RXLisp by Duncan Temple Lang on a MDK
9.1 Linux machine running R 1.8.0 installed from a RPM.
Unfortunately I had a problem loading the shared library into R. Since
I'm a Linux newbie I was not able to solve the problem. Maybe some of
you can help me.

First of all I downloaded the source archive for Xlisp-Stat and
for the RXlisp package. Then, as root, and from /root/ diretory I type the
following commands:

> tar zxvf xlispstat-3-52-18.tar.gz
> tar xzvf RXLisp_0.3-1.tar.gz
> cd RXLisp/xlisp/
> export XLISP_SRC_DIR=/root/xlispstat-3-52-18
> ./install

The compilation was OK, and the file /root/xlispstat-3-52-18/libxlisp.so
was created. Then

> cd
> R CMD INSTALL --configure-args='--with-build-xlisp-dll' RXLisp

OK this as well, except for a warning on a .Rd file.

> cp xlispstat-3-52-18/libxlisp.so /usr/lib
> /sbin/ldconfig
> R

-------------------------------------------------------------------------

I'm a bit confused; the file /usr/lib/R/library/RXLisp/libs/RXLisp.so does
exist, but it seems it can't be loaded. Maybe, the problem is not there.

Do you have any clue of what's going on and how can I fix the problem ?

I hope to be able to install the RXLisp package, I loved the dynamic
graphics capabilities of Xlisp-Stat and it would be very nice to have them
available within R.

Thank you very much for your help.

Luca
