Any solutions to building for an older glibc?
There is only one supported way to do what you want.
You need to build against an old sysroot e.g. --sysroot option
in gcc. With the old system root installed in some path to allow
you to compile against it.
That is equivalent to building on a VM running an older Linux,
which is what I have been doing.
There are dependencies in current tool chains for packages
(or versions) which are not available on old (or, in the case
of RH6.2, ancient) versions of Linux.
