#2 rpy cannot find libR.so

[Anonymous]

I compiled R with shared libraries, and libR.so exists
in /usr/lib/R/bin, but I still get the following error
when importing rpy in python:

ImportError: libR.so: cannot open shared object file:
No such file or directory

Using python2.2

The following suggestion from Tim Churches worked for me:
"""
I just installed RPy on a fresh RH 7.2 system. The R
makefile installs
libR.so to /usr/local/lib/R/bin by default, so in your
.bash_profile
file (or wherever else you want to set it), add

LD_LIBRARY_PATH=/usr/local/lib/R/bin; export LD_LIBRARY_PATH

and log out and log back in again. Then it worked fine.

Setting and exporting the variable LD_LIBRARY_PATH is the best solution, I think. I will update the docs for the next release and the FAQ's in the web page.

i ran into the same issue on debian woody/sid with
python2.2.
the solution for me was:
(from the R src directory)

make distclean
./configure --enable-R-shlib
make
make install
edit /etc/ld.so.conf to add the line /usr/local/lib/R/bin
ldconfig

Release 0.2 contains three ways to fix this problem.

I have been having this problem as well, however I have not yet found a solution that works. I have installed R from source (several times, to make sure that I had the ./configure --enable-R-shlib line correct).
I have tried adding to LD_LIBRARY_PATH, I have tried putting symbolic links to libR.so in various places, but nothing seems to work. I am however sure I have libR.so (I found one comment elsewhere on the internet that I should look for it)

locate libR.so
/usr/local/lib/R/bin/libR.so
/usr/local/lib/R/lib/libR.so

R tells me (using R.home()) that it is /usr/local/lib/R, if this is important.
I'm running Ubuntu 12.04, python 2.7, R-2.15.1. Thanks in advance for the help!
