At run time, searches the path directory for shared libraries.
>>- -R--directory----------------------------------------------><
If the -Rdirectory option is specified both in the configuration file and on the command line, the paths specified in the configuration file are searched first at run time.
The -R compiler option is cumulative. Subsequent occurrences of -R on the command line do not replace, but add to, any directory paths specified by earlier occurrences of -R.
The default is to search only the standard directories.
To compile myprogram.c so that the directory /usr/tmp/old is searched at run time along with standard directories for the dynamic library libspfiles.so, enter:
xlc++ myprogram.C -lspfiles -R/usr/tmp/old
