I tried unpacking a centos7 glibc rpm under /tmp/c7libs on a centos 6 box and trying to run a centos7 version of cat with: LD_LIBRARY_PATH=/tmp/c7libs/lib64:$LD_LIBRARY_PATH LD_PRELOAD="/tmp/c7libs/lib64/ld-linux-x86-64.so.2 /tmp/c7libs/lib64/libc.so.6" /tmp/cat-7 /tmp/test seems to work, but that's not a real demanding test... -- Les Mikesell lesmikesell at gmail.com
