Glibc 2 is the latest version of the GNU C Library. It currently runs
unmodified on GNU Hurd systems and Linux i386, m68k, and alpha systems.
Support for Linux PowerPC, MIPS, Sparc, Sparc 64, and Arm will be in version
2.1. In the future support for other architectures and operating systems
will be added.
On Linux, glibc 2 is used as the libc with major version 6, the successor
of the Linux libc 5. It is intended by the Linux libc developers to
eventually replace libc 5. As of 2.0.6, glibc is considered production
quality. Version 2.1 (due out in the near future) will be ready for main
stream use along with adding more ports and features.
There are three optional add-ons available for glibc 2:
- Crypt
The UFC-crypt package. It is seperate because of export restrictions.
- LinuxThreads
An implementation of the Posix 1003.1c "pthread" interface.
- Locale data
Contains the data needed to build the locale data files to
use the internationalization features of the glibc.
The crypt and LinuxThreads add-ons are strongly recommended... not using
them risks to be incompatible with the libraries of other systems.
(If you do not wish to use them, you must add the option
--disable-sanity-checks when you run configure.)
This HOWTO covers installing the glibc 2 library on an existing Linux
system. It is tailored for users of Intel based systems currently using
libc 5, but users of other systems and alternate libraries (such as glibc 1)
should be able to use this information by substituting the proper filenames
and architecture names in the appropriate places.
The latest copy of this HOWTO can be found as part of the
Linux Documentation Project

Differences between version 1.6 and 1.5:
- Fixed the install instructions of the binary glibc package.
Differences between version 1.5 and 1.4:
- Indexing added Ed Bailey.
- Changed my email address.
