Choosing a Linux version - glibc compatibility
I administer a system building a large suite of programs written in C.
We develop/qa and build the applications on Linux.
Because of customer server Linux compatibility, we build our applications on Redhat 7.3 (for glibc 2.2 compatibility).
These applications run on all of our customers Intel Linux boxes.
However, I now want to make the minimum supported glibc 2.3, so I can upgrade our build boxes (as the 7.3 is getting unmaintainable).
We will inform all glibc 2.2 customers that they have to upgrade (before next release).
So in summary, I have customers on glibc 2.2 (who will have to upgrade), and customers on glibc 2.3 upwards.
My question: what operating system does anyone recommend I move my build servers to? They have to be running an early version of glibc2.3 (or should I just build a glibc -haven't done that before - I guess it has caveats).
