Possible to add newer glibc as supplemental library? - Linux Setup, Configuration & Administration

    Default Possible to add newer glibc as supplemental library?

    I'm running a linux system that is a few years old, based on glibc
    2.1. (Original kernel was 2.2.x series, but I have been using 2.4.x
    for some time now with no problems.) Unfortunately I've been finding
    that many new apps will no longer run with this version of glibc.

    I know that doing a major glibc upgrade is an almost impossibly
    complex and dangerous task. But is it feasible to add a newer glibc as
    an additional library? I've read the glibc2 HOW-TO and it contains
    instructions for adding a "test" glibc which seems to essentially do
    this. Detailed instructions are given for dealing with include files
    and linking when compiling source code with the test library. However,
    this doent is several years old (dated June 1998).

    So is this possible? If so, is can the system be configured so
    precompiled binaries will find and use the additional library, or
    would it only be good for building from source?

    (Actually I expect the real answer will be "bite the bullet and
    upgrade the entire OS," but wanted to check out this possibility
    first...)

    No, it is not. The version you choose affects everything -- not just
    applications but system code as well. You have to upgrade all of it, or
    none of it.

    Yes it is perfectly possible. Currently I have 2.2.5 & 2.3.1 together on
    my system. When installing the newer glibc you may get some file conflicts
    which you have to look into. Larger the gap between the versions, more
    would be such conflicts.

    I guess your best bet would be to upgrade the whole system. Even if you
    add a newer version of glibc, almost certainly current versions of many
    applications will ask for recent versions of other libraries.

    check the Makefile for locations for the install. you can install
    glib in a nonstandard place but make sure it does not update you
    links.
