You might end up with mutually incompatible code versions that makes the recompile world freak out. First, quickpkg your existing glibc Then read the glibc ebuild. You can bypass the version checks, IIRC its an envvar something like "I_AM_VERY_STUPID_OR_VERY_BRAVE". Failing that, just comment out the version checks, redigest the ebuild and run it. The rebuild world Obviously, this is not for the faint of heart. -- alan dot mckinnon at gmail dot com

I think that the only way you can do this is to create a chroot jail, in which you build everything using the old version of glibc (in a very similar way to building a new Gentoo system) and run your application in that. no, you can install glibc in /usr/local and then tell apps to either use the libs in /usr/local or /usr.

The configure script says: These critical programs are missing or too old: as ld How I can compile the from the sources (http://ftp.gnu.org/gnu/glibc/glibc-2.10.1.tar.gz) ? You can use ebuild to build a package, but not install it - then just un-compress it and grab the wanted libs. I will try it on my system first, because I can lean something new. Or if you tell us what arch, someone (me if its compatible) can create a binary pkg for you using quickpkg. It might also be on the livecd/install medium as well - dont have one here to check. I run my Gentoo on amd64 (intel xeon), thank's for help.
