Leading and Bleeding with XFree86 4.0 and KDE 2 Beta - page 2
An Installation Overview
Dep and another colleague had suggested I take a look at my glibc version before installing XF86 4.0 or KDE2, and they recommended 2.1.3. I was at 2.1.1, so the first thing I did was to upgrade. Given how central glibc is to the entire system, I was expecting this to be a nightmare. It actually turned out to be the easiest part of the whole process. I just grabbed the source tarball for glibc 2.1.3 itself, plus the appropriate versions of glibc crypt and linuxthreads. Crypt and linuxthreads get unpacked inside the source directory. Then I ran:
from that same directory. Everything worked fine. (Note that if your previous version of glibc came from an RPM, your RPM database is now out of sync. I made a conscious choice on my machine that I didn't care, but you may want to take a more deliberate installation path and use the rpm command to uninstall the old version after making a careful backup.) You may not even need to do this step; I upgraded because I trusted the people who recommended it, not for a specific technical reason.
