- <TR><TD BGCOLOR="#eeeee0">
- <a href="http://uclibc.org">uClibc</a> (aka µClibc/pronounced yew-see-lib-see)
- is a C library for embedded Linux systems. It is much smaller then the
- <a href="http://www.gnu.org/software/libc/libc.html">GNU C Library</a>, but
- nearly all applications supported by glibc also work perfectly with uClibc.
- Porting applications from glibc to uClibc typically involves just recompiling
- the source code. uClibc supports standard Linux systems (such as x86,
- strongArm, and powerpc), and also supports
- <a href="http://www.uclinux.org">MMU-less (also known as µClinux)</a> systems,
- such as those based on the Coldfire, dragonball, or arm7tdmi micro-controllers.
- If you are building an embedded Linux system and you find that glibc is
- eating up too much space, you should consider using uClibc instead. If you are
- building an ultra fast fileserver with 12 Terabytes of storage, then you probably
- want to use glibc...
- <p>
- <p>
- uClibc is maintained by
- <a href="http://www.codepoet.org/andersen/erik/erik.html">Erik Andersen</a>
- and is licensed under the
- <a href="http://www.gnu.org/copyleft/lgpl.html">GNU LIBRARY GENERAL PUBLIC LICENSE</a>
- . This license allows you to make closed source commercial applications using
- uClibc (Please consider sharing some of the money you make ;-). You do not need
- to give away all your source code just because you use uClibc and/or run on Linux.

- <li> <b>22 December 2001, uClibc 0.9.8 Released!</b>
- <br>
- After many months of initial development, we are pleased to announce the
- release of uClibc 0.9.8. This release should be quite solid, and is very
- usable. This also, hopefully, marks a transition from a slow incubation
- phase to a more methodical release cycle. From now one, there should be
- approximately one release per month.
- <p>
- The source code for this release is available at
- <a href="http://uclibc.org/downloads/">here</a>.

- Do you like uClibc? Do you need support? Do you need some feature

- </A></B></BIG>

- <TR><TD BGCOLOR="#eeeee0">
- Here are a few things on the TODO list:
- <ul>
- <li> Shared library support for all supported architectures.
- We now have our own ld.so, but it needs to be ported to
- support each architecture.
- <li> Shared library support for mmu-less systems. This is
- very doable (think of C++ vtables for example), but will
- take some work.
- <li> Someone (hopefully) needs to volunteer to take the
- <a href="http://www.linuxbase.org/test/">LSB Test Suite</a>,
- pull out the C library testing stuff, and convert it
- (perl script, by hand, I don't care how) into a form
- that is usable without having it take over your entire
- system (i.e. similar to what is currently in the uClibc
- test suite). This will be <em>enormously</em> helpful!
- <li> other things as I think of them.
