We have a grid computing environment, comprised primarily of CentOS 5.10 hosts, that people compile applications on and then run them.
We're mulling an upgrade to CentOS 6.7 and we're wondering if glibc on it would be backwards-compatible with CentOS 5.10 as we won't be able to roll out the upgrade in one go (e.g. it could happen that somebody compiles on 6.7 and then the compile is dispatched to a 5.10 host to execute).
Essentially will glibc-compiled programs on CentOS 6.7 run on CentOS 5.10?
We have had a look at the source of glibc for 6.7 (can't recall the correct version) and we believe it should be but were hoping for a second opinion.
