- <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>

- <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.
- <p>
- <p>
- <p>
- <li> <b>9 August 2002, uClibc 0.9.13 Released</b>
- <br>
- CodePoet Consulting is pleased to announce the immediate availability of
- uClibc 0.9.13. After several days of testing, this release is looking very
- solid. This release fixes three security vulnerabilites in previous
- releases. There was an off-by-one buffer overflow in the group handling
- code, and integer overflows in calloc() and xdr_array().
- <p>
- This release adds native shared library support for the Hitachi
- SuperH architecture, thanks to Stefan Allius and Edie C. Dost. A
- new mmap based malloc was implemented by Miles Bader. This is much
- smarter than the old "malloc-simple" and is now the default for
- mmu-less systems, where it should greatly help reduce memory
- fragmentation and wastage. In addition to these larger items, there
- has been a <em>lot</em> of work done to make uClibc a cleaner, more
- capable, library. Most applications now compile and run without
- any trouble.

- <p>
- Have fun!
- <p>
- <li> <b>11 July 2002, Native uClibc toolchains updated</b>
- <br>
- CodePoet Consulting (i.e. Erik) has released updated native
- uClibc/gcc-3.1 and uClibc/gcc-2.95 toolchains. These toolchains
- build real gcc cross compilers (i.e. not just a wrapper) and create
- executables linked vs uClibc. These toolchains have been tested
- and found working on x86, arm, and mmu-less arm. They should work
- (at least in theory!) for all architectures supported by uClibc.
- <p>
- These toolchains should make it easy to anyone to build uClibc based
- applications. <a href="downloads/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 toolchain (w/C++ support)
- on his Athlon XP 1600 (not counting the time it takes to download
- source code). Your results may vary...

- <li> <b>20 June 2002, uClibc 0.9.12 Released</b>
- <br>
- CodePoet Consulting is pleased to announce the immediate availability of
- uClibc 0.9.12. This release adds an i960 port, an initial alpha port,
- fully working mips shared library support, shared library support fixes
- for on powerpc, and many other improvements. One very exciting new feature
- is nearly complete locale support, thanks to a lot of hard work by Manuel
- Novoa III. uClibc's locale support is <em>much</em> smaller than glibc's,
- though it is also slightly less flexible. This release was delayed by a
- month due to the arrival of a new baby at Erik's house. For those that
- have been anxiously waiting, this release should certainly be worth the
- wait. Have fun!
- <p>
- The <a href="downloads/Changelog">Changelog</a>
- and <a href="downloads/uClibc-0.9.12.tar.bz2">source code</a>
- for this release are available <a href="downloads/">here</a>.
- <li> <b>28 May 2002, Native uClibc/gcc-3.1 toolchain</b>
- <br>
- CodePoet Consulting has released source code and a Makefile to build a
- gcc-3.1 toolchain that natively targets uClibc. Additionally, the
- gcc-3.0.4 and gcc-2.95 toolchains have also been updated. These toolchains
- make it easy to build uClibc based applications. Source code can be
- downloaded <a href="downloads/toolchain/">here</a> and is now much smaller,
- since much of the needed binutils and gcc source code is now downloaded on
- demand. To build the toolchain, simply grab the source, edit the Makefile
- to select where you would like the toolchain installed, and then run 'make'
- and wait for it to compile.
- <p>
- <p><li> <b>10 April 2002, uClibc 0.9.11 Released</b>
- <br>
- CodePoet Consulting is pleased to announce the immediate availability of
- uClibc 0.9.11. This release is primarily focused on fixing the issues that
- have turned up since the last release. Several bugs in the gcc wrapper
- have been fixed, allowing applications such as iproute2 and XFree86 to link properly.
- Large file support has been improved, and a thread locking bug was
- fixed that could cause s*printf calls to deadlock when threading was
- enabled. Several bugs were also fixed with the powerpc, h8300, m68k,
- sparc, and mips architecture support. Many additional applications now
- compile and run perfectly and have been added to the <a
- href="uClibc-apps.html">working applications list</a> .
- <p>
- The <a href="downloads/Changelog">Changelog</a>
- and <a href="downloads/uClibc-0.9.11.tar.bz2">source code</a>
- for this release are available <a href="downloads/">here</a>.
- <p>
- <li> <b>10 April 2002, Native uClibc/gcc-3.0.4 toolchain</b>
- <br>
- CodePoet Consulting has released source code and a Makefile
- to build a gcc-3.0.4 toolchain that natively targets uClibc.
- This brings with it full C++ support for uClibc, including the
- libstdc++ library. A gcc-2.95.x toolchain will also be released
- shortly, but is not yet ready. At this time, only source code and
- a Makefile for the native uClibc toolchain is being released (i.e.
- no binaries, sorry). Source code can be downloaded
- <a href="downloads/toolchain/">here</a>,
- but be aware that the source code is 27 MB.
- <p>
- To build the toolchain, simply grab the source, edit the Makefile
- to select where you would like the toolchain installed. Then
- run 'make' and wait for it to compile. If you do not have a copy
- of uClibc already, it will download the latest daily snapshot.
- <p>
- <li> <b>21 March 2002, uClibc 0.9.10 Released!</b>
- <br>
- CodePoet Consulting is pleased to announce the immediate
- availability of uClibc 0.9.10. This release adds pthreads support
- (including pthreads support for mmu-less systems!). Additionally,
- thanks to Manuel Novoa III, we now have a completely new stdio
- library, which is small, standards compliant, supports pthreads,
- wide/narrow streams, large files, and can even operate in a
- low-memory unbuffered mode. Many, many bugs have been fixed and a
- number of additional applications now compile and run perfectly.
- Even with all these changes, uClibc continues to be very small.
- On x86, a default build of the uClibc C library is still just 168k.
- <p>
- To make things more interesting, the release also adds support for
- C++ constructors and destructors. To make it easy to use uClibc
- when developing C++ applications, this release also provides a
- wrapper for the GNU C++ compiler. Of course, for more complex C++
- applications, such as those using iostreams, a standard C++ library
- (libstdc++) is required. A native GNU toolchain (binutils/gcc) that
- provides libstdc++ linked with uClibc 0.9.10 will be released in the
- next couple of days, so stay tuned.

- <p>
- <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>
- 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.
- <p>
- The source code for this release is available
- <a href="downloads/">here</a>.
- <p>
- <li> <b>26 November 2001, powerpc shared libraries fully working</b>
- <br>
- Dave Schleef finished off the the work needed for shared library support on
- powerpc. There had been a few problems remaining, and those are now squashed.
- So shared libs on powerpc should be working fully now.
- <p>
- <li> <b>14 November 2001, m68 compiles again, Large file support working</b>
- <br>
- About a month ago I synced the header files with glibc 2.2.4 for better
- C++ support and better standards compliance. I forgot to sync up m68k,
- sparc, powerpc, and mipsel. Dave Schleef fixed powerpc while he was fixing
- up the shared lib loader. I just fixed up m68k, sparc, and mipsel so they
- should all compile again.
- <p>
- I also finished up fixing large file support (just enable DOLFS in your
- Config file to enable it) and it is working just great, and greatly increases
- the number of glibc applications that will work "out-of-the-tarball" without
- needing any changes.
- <li> <b>12 November 2001, powerpc shared lib support</b>
- <br>
- Thanks to David Schleef, uClibc now has full shared library support
- on powerpc. This brings full shared library support to x86, ARM, and
- now powerpc. Thanks Dave!
- <p>
- <li> <b>7 November 2001, uClibc application list</b>
- <br>
- uClibc now has a <a href="uClibc-apps.html">list of applications</a>
- that are known to work. If you have any applications to add to the
- list, submissions are welcome!
- <p>
- <li> <b>18 October 2001, buildroot uClibc example system</b>
- <br>
- Those wanting an easy way to test out uClibc and give it
- a test drive can download and compile
- <a href="http://www.uclibc.org/downloads/buildroot.tar.gz">buildroot.tar.gz</a>. This
- is a nifty buildsystem that will automagically download and build
- a <a href="http://user-mode-linux.sourceforge.net/">User-Mode Linux</a>
- kernel, and will then download source for and compile up a fully
- working uClibc based root filesystem. This should make it easy for
- people to create their own projects. I hope that this build system
- will allow people to more easily use and build uClibc based systems.
- As an example of how nicely this works, the
- <a href="http://tuxscreen.net/">Tuxscreen Project</a> is using a
- <a href="http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/tuxscreen/buildroot-tux/">slightly adjusted variant of the buildroot system</a> to cross
- compile the blob bootloader, linux kernel, and a uClibc based jffs2
- root filesystem (busybox, tinylogin, udhcp, lrzsz, pcmcia-cs and
- microwindows) for ARM. Pretty cool.
- <p>
- <li> <b>11 October 2001, v850 architecture support</b>
- <br>
- Miles Bader has contributed support for the v850 architecture.
- <p>
- <li> <b>25 Spetember 2001, header files updated</b>
- <br>
- uClibc's header files are now in sync with glibc 2.2.4,
- allowing better standards compliance, better portibility, and
- better C++ support.
-
- <p>
- <li> <b>4 July 2001, ARM shared library support</b>
- <br>
- uClibc now has full shared library support on ARM.
- <p>
- <li> <b>9 May 2001, libm added</b>
- <br>
- uClibc now has a very complete math library.
- <p>
- <p> <li> <b>9 May 2001, ld.so added</b>
- <br>
- uClibc now has a native ld.so. It currently is only ported to work on x86,
- but porting to other architectures should not be too difficult.
- <p> <li> <b>15 March 2001, powerpc port added</b>
- <br>
- David Schleef contributed a powerpc port, which is now in CVS.
- <p> <li> <b>19 February 2001, SH port added</b>
- <br>
- Jean-Yves Avenard contributed an SH port. See his email
- with the initial patch <a href="/lists/uclibc/2001-February/000409.html">here</a>.
- <p> <li> <b>16 January 2001, uClibc as a shared library</b>
- <br>
- As if January 16, uClibc can now be used (at least on x86) as a shared
- library. See the <a href="/lists/uclibc/2001-January/000126.html">email</a>
- announcing this achievement.
- <p> <li> <b>11 January 2001, gcc wrapper added</b>
- <br>
- Manuel Novoa III has created a wrapper for gcc that makes compiling apps vs uClibc
- as simple as just setting "CC" to gcc-uClibc-< arch>. This even works when cross
- compiling! Very cool.
- <p> <li> <b>3 January 2001, uClibc now has a web page</b>
- <br>
- A lot of work has been going on under the hood with uClibc,
- so I decided to put together this webpage to let the world know
- that it exists and is getting to be very usable.
