no.  use a dedicated chroot, or create a cross-compiler that simply links
against the older glibc.  the former is probably easiest as you can grab an
old distro and unpack it.

Exactly.

You want to build yourself an x86->x86 cross-compiler that has a sysroot with an old glibc.

It's the *easiest* way to go.

The alternatives are all pretty ugly, but LSB has been working to solve this problem for quite a while. It's taking time to fix.

For example Flexera Software's FlexNet Publisher (FlexLM) on Linux is now LSB compliant. Kudos to them for doing the work!

The more distros that sign up to work with LSB the better this is going to be...

Cheers,
Carlos.
