This is in contrast to the -L dir option which indicates at buildtime where to find the library specified by a -l library option, but does not record this path into the binary executable.

The directory paths that were built in when the executable was created can be viewed using the dump command. At runtime , the linker determines where to find the dynamic libraries that an executable needs from:. The paths that had been specified by -R at the time the executable file was built.
