[R] Rstudio R-devel libR.so

[Karim Mezhoud]

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.

$rstudio
R shared library (/usr/local/R-devel/lib/libR.so) not found.
If this is a custom build of R, was it built with the --enable-R-shlib
option?
