I haven't gotten back to this yet, but I think the right answer to this question would have been to install the compat-glibc package: Description : This package contains stub shared libraries and static libraries : from CentOS Linux 6. : : To compile and link against these compatibility libraries, use : gcc -fgnu89-inline \ : -I /usr/lib/x86_64-redhat-linux6E/include \ : -B /usr/lib/x86_64-redhat-linux6E/lib64/ -- Les Mikesell lesmikesell at gmail.com
