<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 the 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 for your company 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 marks a transition from a slow incubation phase to a more
    methodical release cycle.  For now one, there should be approximately one release
    per month.  
    <p>
    You can find the source code for this release 
	<a href="http://uclibc.org/downloads/">here</a>.

    <li> uClibc also has a publically browsable
	<a href="http://cvs.uclinux.org/cgi-bin/cvsweb/uClibc/">CVS tree</a> (this CVS tree is also mirrored onto

	Do you like uClibc?  Do you need support?  Do you need some feature
	added to uClibc?  Then why not help out?  We are happy to accept
	donations, provide support contracts, and implement funded feature
	requests.  Additionally, uClibc is looking for corporate sponsors to
	assist development, pay for bandwidth, and help with hardware
	donations, especially donations of hardware for non-Intel
	architectures.  Click here to help support uClibc and/or request

    TODO
    </A></B></BIG>
</TD></TR>
<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.
