- <TR><TD BGCOLOR="#eeeee0">
- <a href="http://www.uclibc.org">uClibc</a> (aka µClibc/pronounced
- yew-see-lib-see) is a C library for developing embedded Linux systems.
- It is much smaller than 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 even supports shared libraries
- and threading. It currently runs on <a href="http://kernel.org/">standard Linux</a>
- and <a href="http://www.uclinux.org">MMU-less (also known as µClinux)</a>
- systems with support for alpha, ARM, i386, i960, h8300, m68k, mips/mipsel,
- PowerPC, SH, SPARC, and v850 processors.
- <p>
- 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, than using
- glibc may be a better choice...
- <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.
- <p>
- <h3>Mailing List Information</h3>
- uClibc has a <a href="/lists/uclibc/">mailing list</a>.<br>
- To subscribe, go and visit
- <a href="http://www.uclibc.org/mailman/listinfo/uclibc">this page</a>.
- <p>
- <h3>Frequently Asked Questions</h3>
- Before asking questions on the uClibc mailing list,
- you might want to take a look at the
- <a href="FAQ.html">list of Frequently Asked Questions</a>
- or
- you might want to search the mailing list archives...
- <form method="GET" action="http://www.google.com/custom">
- <input type="hidden" name="domains" value="uclibc.org">

- </form>
- <h3>Working Applications List</h3>
- These days, pretty much everything compiles with uClibc. This
- is a <a href="uClibc-apps.html">list of applications</a> that are known
- to work just fine with uClibc. Since most applications work just
- fine with uClibc, we are especially interested in knowing about any
- applications that either <em>do not compile</em> or <em>do not work</em>
- properly with uClibc. Submissions are welcome!

- <p>
- <li> <b>6 March 2003, development system updates</b>
- <br>
- The uClibc development systems for
- <a href="http://www.uclibc.org/downloads/root_fs-i386.bz2">i386</a>,
- <a href="http://www.uclibc.org/downloads/root_fs-powerpc.bz2">powerpc</a>,
- <a href="http://www.uclibc.org/downloads/root_fs-arm.bz2">arm</a>,
- and now for the first time
- <a href="http://www.uclibc.org/downloads/root_fs-mipsel.bz2">mips</a>,
- have been updated to uClibc 0.9.19. Several smaller problems
- have also been fixed up.
- <p>
- This is an ext2 filesystem that runs natively on the specified
- architecture. It contains all the development software you need to build
- your own uClibc applications, including bash, coreutils, findutils,
- diffutils, patch, sed, ed, flex, bison, file, gawk, tar, grep gdb, strace,
- make, gcc, g++, autoconf, automake, ncurses, zlib, openssl, openssh and
- more. And of course, everything is dynamically linked against uClibc. By
- using a uClibc only system, you can avoid all the painful
- cross-configuration problems that have made using uClibc somewhat painful
- in the past. If you want to quickly get started with testing or using
- uClibc you should give these images a try. You can loop mount and
- then chroot into them, you can boot into them using user-mode Linux,
- you can even 'dd' them to a spare partition and use resize2fs to
- make them fill the drive. Whatever works best for you.
- <p>
- Have Fun.
- <p>
- <p>
- <li> <b>3 March 2003, uClibc 0.9.19 Released</b>
- <br>
- CodePoet Consulting is pleased to announce the immediate availability of
- uClibc 0.9.19. This is once again primarily a bug-fix release. Several
- critical problems with system calls were fixed, the pthreads library was
- improved, debugging of applications using uClibc's pthreads library is
- now possible (requires gdb 5.3 or newer that is compiled using uClibc),
- and a number of other random fixes are included. This release retains
- binary compatibility with uClibc 0.9.18 (except for mips, which didn't
- work properly with uClibc 0.9.18 anyways). Updated development system
- images compiled with uClibc 0.9.19 will be released shortly.
- <p>
- As usual, the
- <a href="http://www.uclibc.org/downloads/Changelog">Changelog</a> and <a
- href="http://www.uclibc.org/downloads/uClibc-0.9.19.tar.bz2">source code for this release</a>
- are available <a href="http://www.uclibc.org/downloads/">here</a>.
