Depends which older version you need; the compat-glibc package provides binary compatibility with the n-1 distro: $ yum info compat-glibc [....] Summary: Compatibility C library Description: This package contains stub shared libraries and static libraries from Red Hat Enterprise Linux 4. To compile and link against these compatibility libraries, use gcc34 -I /usr/lib/i386-redhat-linux4E/include \ -B /usr/lib/i386-redhat-linux4E/lib/ Pierre Bourgin
