Dear All,
I am actually on R-devel using shell consol. When I run RStudio, it can't
find libR.so in the new /lib folder where is libRblas.so libRlapack.so.
At first step I configure R-devel to share library with ./configure
--enable-R-shlib.
when I copied libR.so from /usr/lib/R/lib/libR.so (stable version R 3.1)
to /usr/local/R-devel/lib/libR.so (R-devel version), That doesn't work.
please find the detail at below.

If this is a custom build of R, was it built with the --enable-R-shlib
option?

When I get a symbolic link with:

The R session had a fatal error.
