uClibc -- a C library for embedded systems

</A></B></BIG>
</TD></TR>
<TR><TD BGCOLOR="#eeeee0">
<a href="http://www.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 architectures (such as x86,
strongArm, and powerpc), and also supports
<a href="http://www.uclinux.org">MMU-less (also known as µClinux)</a>
architectures such as the Coldfire, Dragonball, and 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. If you are
building a huge fileserver with 12 Terabytes of storage, then using
glibc may be a better choice...
<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.

<ul>
<li> <b>4 February 2002, uClibc 0.9.9 Released!</b>
<br>
CodePoet Consulting is pleased to announce the immediate
availability of uClibc 0.9.9. With this release,
<a href="uClibc-apps.html">just about
everything we have tested now compiles and runs</a>. In fact,
there are now so many programs on the working application list that
rather than continue to add to this list, from now on we
will only be adding applications to the <em>not working list</em>. Most applications
on the <em>not working list</em> either require pthreads, or require
wide-character support. Work on wide-character support is
well underway, and will hopefully be moving into CVS in the next week or
two. Full pthreads support and rentrancy are on the TODO list
and are expected to be complete in the next couple of months.
<p>
Another very nice change is that we can now build full GNU
toolchains (binutils/gcc) that target uClibc. This brings
full C++ support to uClibc. A C++ toolchain is currently being
tested, and will be publicly released in the next couple of days,
so stay tuned.
<p>
The <a href="downloads/Changelog">Changelog</a>
and <a
href="downloads/uClibc-0.9.9.tar.bz2">Source code</a>
for this release are available <a href="downloads/">here</a>.
<p>
One final bit on news -- as some of you may have noticed, uclibc.org
has been a bit overloaded and somewhat slow recently. The server should
be getting colocated tomorrow, which will eliminate the speed problem.
During the move, there may be some temporary disruption of service...
<p>
Have Fun!
<p>
<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.

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
features.

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.
