Is this related to Rserve installer does not work well with Redhat enterprise 5 ? It complain about cannot find -lR , I have difficulty understanding the gcc command line: gcc -std=gnu99 Rserv.o session.o md5.o -o Rserve -L/usr/lib64/R-2.14.0/lib -lR -ldl -lcrypt /usr/bin/ld isn't -lR a parameter to gcc ? Why it complains about -lR not found?
