- <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>
- You might want to take a look at the
- <a href="FAQ.html">list of Frequently Asked Questions</a>
- before asking questions on the mailing list...
-
-
- <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!

- <li> <b>16 September 2002, gcc-3.2 and gcc-2.95 toolchains released</b>
- <br>
- CodePoet Consulting (i.e. Erik) has released updated gcc-3.2 and gcc-2.95
- uClibc toolchains. These toolchains build real gcc cross compilers (i.e.
- not just a wrapper) and create executables linked vs uClibc. The new
- gcc-3.2 provides uClibc support with the latest and greatest compiler
- available from the gcc team. The gcc-2.95 toolchain has been updated to
- the latest version of uClibc and now provides full C++ support, using the
- <a href="http://www.stlport.org/">STLport</a> standard C++ library.
- <p>
- This toolchain should make it easy for anyone to build uClibc based
- applications. <a href="http://www.kernel.org/pub/linux/libs/uclibc/toolchain/">
- Source code can be downloaded here</a>.
- Be aware that much of the needed source code will actually be downloaded on
- when you compile the toolchains. To build a toolchain, simply
- grab the source, edit the Makefile to select where you would like
- the toolchain installed, run 'make', and then go watch TV, eat
- dinner, or visit with your friends while it compiles. It takes
- about 15 minutes for Erik to compile the gcc-3.2 toolchain (w/C++ support)
- on his Athlon XP 1600 (not counting the time it takes to download
- source code).
- <p>
- <p>
- <li> <b>27 August 2002, uClibc 0.9.15 Released</b>
- <br>
- CodePoet Consulting is pleased to announce the immediate availability
- of uClibc 0.9.15. This release fixes a number of problems that turned
- up since the last release. The good news is that uClibc now
- passes all tests in the perl 5.8 and Python 2.2.1 test suites, both with
- and without pthreads. So without any further ado....
- <p>
- The
- <a href="http://www.us.kernel.org/pub/linux/libs/uclibc/Changelog">Changelog</a>
- and <a href="http://www.us.kernel.org/pub/linux/libs/uclibc/uClibc-0.9.15.tar.bz2">source code</a>
- for this release are available <a href="http://www.us.kernel.org/pub/linux/libs/uclibc/">here</a>.
- <p>
- Have fun!
- <p>
-
- <p>
- <li> <b>12 August 2002, uClibc 0.9.14 Released</b>
- <br>
- CodePoet Consulting is slightly less pleased then usual to announce the
- immediate availability of uClibc 0.9.14. This is, unfortunately, a bugfix
- release intended to fix the couple of dumb things that slipped into the
- previous release. Version 0.9.13 of uClibc would fail to compile when
- enabling both RPC and Pthreads. There was also a problem with RPC thread
- local storage (but noone noticed since it didn't compile ;-). Also, the
- thread locking in exit(), onexit() and atexit() was broken, and wasn't
- actually locking anything. This release also fixes uClibc's gcc wrapper
- to use crtbeginS.o and crtendS.o when compiling PIC code, fixing a subtle
- bug (that was much less subtle on powerpc). Finally, this release includes a
- few minor compile warning cleanups.
- <p>

- <a href="http://www.us.kernel.org/pub/linux/libs/uclibc/Changelog">Changelog</a>
- and <a href="http://www.us.kernel.org/pub/linux/libs/uclibc/uClibc-0.9.14.tar.bz2">source code</a>
- for this release are available <a href="http://www.us.kernel.org/pub/linux/libs/uclibc/">here</a>.
- <p>
- Have fun!
- <p>
-
- <li> <b>12 August 2002, Native uClibc/gcc-3.1.1 toolchain released</b>
- <br>
- CodePoet Consulting (i.e. Erik) has released an updated native
- uClibc/gcc-3.1.1 toolchain. This toolchain builds a real gcc cross
- compiler (i.e. not just a wrapper) and creates executables linked vs
- uClibc. This toolchain has been (briefly) tested as working on x86, arm,
- mips, and arm7tdmi (uClinux). This toolchain provides a number of
- improvements over previous releases. In particular, Steven J. Hill found
- and fixes a number of "glibc-isms" in the libstdc++ math support which
- caused a number of math functions to be mapped to the non-standard named
- under GNU libc. This release also includes greatly improved uClinux
- "elf2flt" support, and it now produces working flat binaries for my
- uClinux/arm7tdmi system. The native uClibc/gcc-2.95 toolchain will be
- updated in a few days, and will include STLport which will allow that
- toolchain to also provide full C++ support.
- <p>
- This toolchain should make it easy for anyone to build uClibc based
- applications. <a href="http://www.us.kernel.org/pub/linux/libs/uclibc/toolchain/">
- Source code can be downloaded here</a>.
- Be aware that much of the needed source code will actually be downloaded on
- demand when you compile things. To build the toolchain, simply
- grab the source, edit the Makefile to select where you would like
- the toolchain installed, run 'make', and then go watch TV, eat
- dinner, or visit with your friends while it compiles. It takes
- about 15 minutes for Erik to compile the gcc-3.1.1 toolchain (w/C++ support)
- on his Athlon XP 1600 (not counting the time it takes to download
- source code). Your results may vary...
- <p>
- <li> <b>9 August 2002, uClibc now mirrored on kernel.org!</b>
- <br>
- uClibc is now available from the kernel.org mirrors! This should make
- uClibc downloads much faster. The kernel.org mirrors will have all
- uClibc release versions (everything but the daily snapshots).
- Here is a list of all the <a href="http://kernel.org/mirrors/">kernel.org mirror sites</a>.
- Just pick the closest mirror site, and then go to "/pub/linux/libs/uclibc/"
- to download uClibc. For example, is you live the USA, you can go to
- <a href="http://www.us.kernel.org/pub/linux/libs/uclibc/">
- http://www.us.kernel.org/pub/linux/libs/uclibc/</a> to download the latest
- uClibc release from a nice fast system.
