Hi all,
I am trying to compile gap4b2 on a libc6 based debian/linux system,
but compilation fails at start, printig the following:

What does it mean?

lbc6 is still an experimental development, moreover it's not fully libc5
compatible.
Debian does support libc6, but only as an *unstable* package.

I suppose GAP 4 is based on libc5.

Probably it's wise to stuck to libc5 for the time being.

Not that it helps much... :-(
Dima.
