Debian libc5 to libc6 Mini-HOWTO
Scott K. Ellis, [EMAIL PROTECTED]
v1.3, August 14, 1997
1. Introduction
The Debian project is currently in the process of putting together the
next release of the Debian system. This version will utilize the new
libc6, a replacement for the prior libc5 which includes many
enhancements and brings the linux C library back into sync with the
GNU project. We are doing this in a way to allow you to continue to
utilize your older software by providing development and operating
environments for both C libraries. However, all packages in the new
release will be linked with the new C library. This has made it
slightly more difficult to install packages from the unstable branch
of our development tree into a working system. There is a slight
possibility of making your system unbootable in the process, this
guide is intended to help you avoid such problems.
2. Minimum requirements
The minimum list of packages to install to be able to run unstable-
branch packages is below. Install these packages one at a time in
exactly the order listed. When versions are mentioned, that is a
minimum suggested version, any later version should also be
acceptable.
o libc6_2.0.4-1
o ldso_1.9.5-1
o ncurses3.4_1.9.9g-3
o libreadline2_2.1-2.1
o libreadlineg2_2.1-2.1
o bash_2.01-0.1
3. Development
If you wish to do libc6 development, you should first purge all the
'-dev' packages on your system, the new development system will use
packages with the suffix '-dev' for libc6 development and '-altdev'
for libc5 development. You will wish to install the latest libc5
package, and altgcc if you wish continue to do libc5 development as
well. Some libraries haven't been recompiled for the new libc6 yet,
check that all your vital libraries are available before upgrading.
Linking libc5-based libraries with libc6-based programs will have
unpredictable results.
4. Concerns
Note also that both the man-db and the libc6-dev packages currently
include /usr/bin/gencat. The version of gencat in libc6-dev has been
reported to cause segfault problems with man-db, you may wish to
reinstall man-db after libc6-dev if you experience these problems.
5. Disclaimer
As always, this document comes with NO WARRANTY. These comments are
based on my personal experience and experimentation. While this
worked for me off a freshly installed v1.3.1 system, you milage may
vary. Please send any comments or corrections to [EMAIL PROTECTED]
