These steps will allow you to upgrade
glibc to 2.3.x on a
system with a 2.4.x kernel. I just completed this upgrade from glibc-2.2.4 to glibc-2.3.2. Be strongly
forewarned that performing this procedure incorrectly
can & will result in an unbootable and unusable
system. Have a good boot/root disk with a copy of
your present /lib on it before starting.
Do not contact me if you trash your system, you have been forewarned.
1) First download the latest stable version of
the corresponding version of glibc-linuxthreads-2.x from here: http://www.gnu.org/software/libc/
Note that you'll also need the latest stable version of make (at the time of this writing it is 3.80) from here:
To build glibc 2.3.x, you'll also need gcc-3.x from here:
If you need help building gcc-3.x, see this SxS.
2) Copy the old
Also make a backup copy of /lib:
cp -a /lib /lib.bak
3) Untar, extract the newly downloaded
glibc tarball in /usr/src/
4) Untar, extract the newly downloaded
glibc-linuxthreads tarball in the newly
created /usr/src/glibc-2.x/ directory
5) From within /usr/src/
run " mkdir glibc-build " and then cd
6a) Run the following command (adjust the version):
../glibc-2.x/configure --enable-add-ons --libexecdir=/usr/bin --prefix=/usr
Note, if you are building glibc-2.3.2 with gcc-3.3 you must first apply this patch to /usr/src/glibc-2.3.2/stdio-common/sscanf.c like so:
patch /usr/src/glibc-2.3.2/stdio-common/sscanf.c sscanf.c.patc
6b) Additionally, verify that you do NOT have the following symlinks:
/usr/include/linux -> /usr/src/linux/include/linux
/usr/include/asm -> /usr/src/linux/include/asm-i386
/usr/include/scsi -> /usr/src/linux/include/scsi
If those symlnks exist, you MUST
delete the symlinks (not the directories that they point to), and
create directories in their place. Failing to replace the
symlinks with static directories will result in missing and/or out of
7) Next run this command:
make && make install && make localedata/install-locales
8) Run "/sbin/ldconfig "
That is all, if everything works then you're done, and
you will have glibc-2.3.x successfully installed.
