Error loading shared libraries: libR.so

I Have R version - 3.x.x .

when i was trying to execute R ,
got error :
error while loading shared libraries: libR.so: cannot open shared object file: No such file or directory.

Have you installed R from source? If so, have you included the --enable-R-shlib flag when compiling?

@andresrcs. I tried but it did not solve my problem. It is reproducible again.
