- 12 January 2005, uClibc 0.9.27 Released
  CodePoet Consulting is pleased to announce the release of uClibc 0.9.27. Release highlights include a new stdio core, Linux 2.6.x support, a much improved shared library loader, support for several new architectures, and of course fixes for the usual pile of bugs.

  Due primarily to the stdio changes, this release is NOT binary compatible with uClibc 0.9.26 or any earlier release, so be prepared to recompile your software if you are still using an old version of uClibc. Sorry for the pain...

  Updated uClibc development systems using uClibc 0.9.27, along with the uClibc buildroot and source code used to compile these development systems, have also been released and are available from the uclibc.org downloads area.

  As usual, the Changelog, detailed changelog, and source code for this release are available here.

- 20 April 2004, uClibc 0.9.26 based Debian uwoody
  CodePoet Consulting (i.e. Erik) is pleased to announce the immediate availability of an x86 port of Debian woody compiled with uClibc 0.9.26. This was originally announced a couple of months ago, but has been updated a few times since to correct several small problems. If you want an easy way to start building your own uClibc based applications, this is it. This even supports building your own packages using 'apt-get', and using 'apt-get' to install already compiled packages from uclibc.org. You can find Erik's uwoody distribution uwoody distribution here. Assembling this Debian/uClibc system required a lot of work, so if you think this is the coolest thing since the invention of water, feel free to let us know.

- 3 January 2004, uClibc 0.9.26 Released
  CodePoet Consulting is sorry to announce there was a pthread bug that slipped though our extensive testing and was only noticed a few hours after the previous release. As a result, we are now releasing uClibc 0.9.26 which fixes this bug, and is otherwise identical to the previous release.

  This release remains binary compatible with uClibc 0.9.21-25, as long as you take care to avoid any configuraton changes that will break things. Please be aware we will break binary compatibilty in the upcoming 0.9.27 release to implement a few necessary changes we have been postponing. That will hopefully be the last ABI change before we freeze the ABI for the upcoming 1.0.x stable uClibc series.

  As usual, the Changelog, detailed changelog, and source code for this release are available here.

- 3 January 2004, uClibc 0.9.25 Released
  CodePoet Consulting is pleased to announce the immediate availability of uClibc 0.9.25. This contains many bug fixes and cleanups, and is recommended for anyone using uClibc. This release remains binary compatible with uClibc 0.9.21-24 (as long as you take care to avoid any configuraton changes that will break things). We were planning to break binary compatibilty in this release, but decided to hold those changes so we could push out a bugfix release.

  Please be aware we will break binary compatibilty in the upcoming 0.9.26 release to implement a few changes we have been postponing. That will hopefully be the last ABI change before we freeze the ABI for the upcoming 1.0.x stable uClibc series.

  As usual, the Changelog, detailed changelog, and source code for this release are available here.

- 19 December 2003, dev systems updated to uClibc 0.9.24
  Current uClibc development systems have been posted for i386, powerpc, arm, mips, mipsel, and sh4. The powerpc dev system mostly works, but there are still some problems with the shared library loader that have not yet been resolved. Details on what these are and how to use them can be found in the FAQ

- 15 December 2003, uClibc 0.9.24 Released
  CodePoet Consulting is pleased to announce the immediate availability of uClibc 0.9.24. This contains various minor updates and fixes for a few silly configuration problems. Arm users should notice a speed increase since some arm optimized string functions have been added. And several bugs have been fixed.

  This release continues to be binary compatible with uClibc 0.9.21 to 0.9.23 -- as long as you pick compatible configuration options. The next release will not be binary compatible. We've been saving up a few needed changes that will be going into the next release, so while you will not need to recompile all your applications and libraries just yet, keep in mind we will have a flag day soon...

  As usual, the Changelog, detailed changelog, and source code for this release are available here.

- 13 November 2003, uClibc 0.9.23 Released
  CodePoet Consulting is pleased to announce the immediate availability of uClibc 0.9.23. Of course, we are somewhat less than pleased that there were configuration problems in the previous release that made such it necessary to release .23 so quickly. Updated uClibc development systems using uClibc 0.9.23 are being built and will be posted shortly. And Erik has built Debian stable (woody) for x86 with uClibc and it runs great.

  This release continues to be binary compatible with uClibc 0.9.21 and 0.9.22 -- as long as you pick compatible configuration options. Enabling or disabling things like soft-float, locale, wide char support, or changing cpu optimizations are all good examples of binary incompatible configuration options. If have changed any of those sorts of options (or if you are not sure!) you will need to recompile all your applications and libraries.

  As usual, the Changelog, detailed changelog, and source code for this release are available here.

- 8 November 2003, uClibc 0.9.22 Released
  CodePoet Consulting is pleased to announce the immediate availability of uClibc 0.9.22. This release has been cooking for a couple of months now and is looking quite solid. We have done quite a lot of testing with this release and things are looking good. And Erik has built Debian stable (woody) for x86 with uClibc and it runs great. Expect that to be released in the next few days.

  This release is binary compatible with uClibc 0.9.21 -- as long as you pick compatible configuration options. Enabling or disabling things like soft-float, locale, wide char support, or changing cpu optimizations are all good examples of binary incompatible configuration options. If have changed any of those sorts of options (or if you are not sure!) you will need to recompile all your applications and libraries.

  Updated uClibc development systems using uClibc 0.9.22 will be made available within a few days. Meanwhile, we invite you to try out uClibc with the latest Linux Test Project test suite (you will need to apply a small patch. And also give the latest Perl and Python test suites a try as well. If you find any bugs in uClibc, PLEASE let us know!

  As usual, the Changelog, detailed changelog, and source code for this release are available here.

- 30 September 2003, dev systems updated to uClibc 0.9.21+
  The uClibc development systems for i386, powerpc, arm, mips, have been updated to uClibc 0.9.21 (plus all the CVS updates up to today). Several problems have been fixed up, gcc has been updated to version 3.3.1, binutils was updated to 2.14.90.0.6, and tada everything finally works for cross compiling. These were all cross compiled (which really makes things faster since the older mipsel releases used to take 2 days to build!)

  These are ~100 MB ext2 filesystems that run natively on the specified architecture. They 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 perl, 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 them you can chroot into them, you can boot into with using user-mode Linux, and you can even 'dd' them to a spare partition and use resize2fs to make them fill the drive. Whatever works for you.

  If you would like to build your own custom uClibc system, you can use buildroot, which is how these uClibc development systems were created.

- 9 September 2003, uClibc 0.9.21 Released
  CodePoet Consulting is pleased to announce the immediate availability of uClibc 0.9.21. This release has been brewing for several months now, and provides quite a lot of additional functionality and quite a few bug fixes as well. Many people will be pleased that this release fixes the "dlopen()'ing libraries that depend on libraries" problem.

  The biggest thing in this release (and I do mean that literally) is that uClibc now has full ANSI/ISO C99 locale support. Well, except for wcsftime() and collating items in regex, which are not done yet. Adding support for the default set of locales (169 UTF-8 locales and 144 locales using other codesets) will enlarge uClibc by around 300k. Still, if you need locale support, that is still much better than the roughly 30MB the comparable set of locale date occupies with glibc. And you can of course reduce the 300k by reducing the number of supported locales.

  As usual, this release has many improvements, both large and small. At this point, most applications that compile and work with glibc will also compile and run with uClibc. Both Perl and Python pass all the tests in their test suites (both with and without locale support enabled). We invite you to grab a copy of the latest Linux Test Project test suite and give uClibc some abuse. We are not yet perfect, but we are getting pretty darn close.

  This release is not binary compatible with earlier releases. Depending on your configuration, you may actually still be binary compatible, but it would be a good idea to recompile your applications when moving to the uClibc 0.9.21 release. We are sorry about that, but we have never promised to provide binary compatibility until we hit version 1.0. And even then, if you change your uClibc configuration, you still still generally need to recompile...

  As usual, the Changelog, detailed changelog, and source code for this release are available here.

  Updated uClibc development systems using uClibc 0.9.21 will be made available within a few days.

- 30 June 2003, uClibc 0.9.20 Released
  CodePoet Consulting is pleased to announce the immediate availability of uClibc 0.9.20. This is primarily a bug-fix release. This release remains binary compatible with 0.9.18 and 0.9.19 (as long as you leave the new UCLIBC_HAS_TM_EXTENSIONS option disabled), so you don't have to recompile everything if you don't really feel like it.

  This release has many small improvements. At this point, most applications that compile and work with glibc will also compile and run with uClibc. Perl and Python even pass all the tests in their test suites.

  There is currently one notable exception. Applications that use dlopen() to load libraries that themselves depend on other libraries, may have weak symbols within those depended-upon libraries resolved incorrectly. This problem is currently being worked on. Other than that, everything seems to now be working as expected....

  As usual, the Changelog, detailed changelog, and source code for this release are available here.

- 30 June 2003, dev systems updated to uClibc 0.9.20
  The uClibc development systems for i386, powerpc, arm, mips, have been updated to uClibc 0.9.20. Several problems have been fixed up, gcc has been updated to version 3.3, and Perl 5.8.0 is now included.

  This is a 150 MB 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 perl, 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.

Whatever works for you.

  If you would like to build your own custom uClibc system, you can use buildroot, which is how the uClibc development systems were created.

- 6 March 2003, development system updates
  The uClibc development systems for i386, powerpc, arm, and now for the first time mips, have been updated to uClibc 0.9.19. Several smaller problems have also been fixed up.

  This is an ext2 filesystem that runs natively on the specified architecture.

Whatever works best for you.

  Have Fun.

- 3 March 2003, uClibc 0.9.19 Released
  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.

  As usual, the Changelog and source code for this release are available here.

- 17 February 2003, development system updates
  The uClibc development systems for i386 and powerpc, and arm have been again updated. This time around a few broken symlinks (one preventing C++ code from compiling) have been fixed, several system calls related to uids and gid have been fixed, the powerpc system call mechanism has been updated, and GNU tar and GNU grep have been added. gcc, gcc+, ssh, etc are all still included and things remain binary compatible with uClibc 0.9.18. Have Fun.

- 12 February 2003, development system updates
  The uClibc development system has had a number of problems fixed, and has been updated for uClibc 0.9.18. The i386 and powerpc, and arm devel systems are updated and ready to download and use. Have Fun.

- 12 February 2003, uClibc 0.9.18 Released
  CodePoet Consulting is pleased to announce the immediate availability of uClibc 0.9.18. This is primarily a bug-fix release, as there were a few directory handling problem that could cause application using uClibc 0.9.17 to either segfault or lose the first character when reading directry names. Unfortunately, once again, this release is _NOT_ binary compatible with earlier uClibc releases. I _think this will be the last time (with the possible exception of some future changes to our locale support...)

  As usual, the Changelog and source code for this release are available here. You might want to download uClibc from the closest kernel.org mirror site. Just pick the closest mirror site, and then go to http://www.XX.kernel.org/pub/linux/libs/uclibc/ to download uClibc, where XX is your two letter country code.

- 25 January 2003, uClibc 0.9.17 Released
  CodePoet Consulting is pleased to announce the immediate availability of uClibc 0.9.17. The biggest piece of news with this release, thanks to Manuel Novoa's continuing hard work, is that we now have fully standards compliant locale support (optional of course). The support works nicely, (though configuring the locales you wish to support is still manual -- a task for the next release). Full locale data for over 300 locales adds approximately 250k. The collation data for all supported locales is roughly 180k. This may seem rather large to some -- but it is much smaller than the approximately 40 MB needed by Glibc to provide the same data. And if you don't need it, you can either disable locale support entirely, or enable a smaller set of locales.

  This release also fixes lots and lots of bugs. The arm architecture support (I am embarrassed to note) was totally broken in the last release, but is now working as expected. A security problem (a buffer overflow in getlogin_r) was fixed. And there were architecture updates across the board (x86, arm, powerpc, cris, h8300, sparc, and mips). And of course, this release includes the usual pile of bug fixes. Many thanks for the large number of patches and fixes that were contributed!

  Unfortunately, this release is not binary compatible with earlier uClibc releases. As noted as item 3 here, uClibc does not (yet) attempt to ensure binary compatibility across releases. We will eventually do that (once we reach the "1.0" release) but not yet. A few bugs turned up that needed to be fixed, and the only good way to fix them was to change some fundamental data structure sizes. As a result, this release is _NOT_ binary compatible with earlier releases -- you will need to recompile your applications. The x86, arm, powerpc, and mips architectures (i.e. the systems Erik has available in his office for testing) have been tested and are known to work following this change. Other architectures may need additional updates. Sorry about that, but it had to be done.

  As usual, the Changelog and source code for this release are available here. You might want to download uClibc from the closest kernel.org mirror site. Just pick the closest mirror site, and then go to http://www.XX.kernel.org/pub/linux/libs/uclibc/ to download uClibc, where XX is your two letter country code.

- 25 January 2003, dev system updates, arm image released
  A number of additional problems have been fixed and the arm build is now, finally, compiling and working as expected. As such, I have updated the i386 development system image, the powerpc development system image, and I am also releasing upon an unsuspecting world the brand new arm development system image! Have fun!

  All three development system images were compiled and built using the stock buildroot system. These were also built using the (about to be announced in a couple on minutes) uClibc 0.9.17 release, so if you want to begin compiling and testing stuff with uClibc, but you don't feel like spending the _hours_ it takes to download, configure, and build your own uClibc based development system -- then you may want to download these and give them a try. They each contain a 100 MB ext2 filesystem with everything you need to begin compiling your own applications. I have (at least minimally) tested each of them and verified that the included gcc and g++ compilers produce working uClibc linked executables.

  Oh, and I have also have updated the uClibc/gcc toolchain builders, so if you just want a simple uClibc/gcc toolchain, one of these should work for you.

- 10 January 2003, dev system updates, powerpc image released
  A few problems showed up in yesterday's development system release (adduser was broken, gdb didn't work, libstdc++ shared libs were missing, etc). So I've updated the i386 development system image to fix these problems. Also, the powerpc development system image has finally finished compiling and is now released upon an unsuspecting world. Have fun!

- 9 January 2003, uClibc development system released
  CodePoet Consulting (i.e. Erik) has been working hard on buildroot recently, and is pleased to offer a full stand-alone uClibc-only development system. This is an ext2 filesystem for i386 containing all the development software you need to build your own uClibc applications. With bash, awk, make, gcc, g++, autoconf, automake, ncurses, zlib, openssl, openssh, gdb, strace, valgrind, busybox, GNU coreutils, and more, this should have pretty much everything you need to get started building your own applications 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. A powerpc and an arm version are in progress. Expect them to be released shortly....

  The uClibc development system is an 18MB bzip2 compressed ext2 filesystem, so be prepared to wait if you are on a slow link. If you wish to have more space, you can loop mount it and 'cp -a' the contents to their own partition, or do what I did... WARNING, the following can be very dangerous. Please be sure you know what you are doing before trying this. I am not responsible if you lose all your important data.I had a spare hard drive (in my case /dev/hdg but you'll want to adapt this to your own needs), so I partitioned it with a single ext2 partition filling the drive (in my case /dev/hdg1). Then I ran:

          bzcat root_fs_i386.bz2 | dd of=/dev/hdg1
          e2fsck -f /dev/hdg1
          resize2fs -p /dev/hdg1

  which overwrote everything on /dev/hdg with the new uClibc devel system, and then expanded the filesystem with the uClibc devel system till it filled the whole drive.

- 8 November 2002, uClibc 0.9.16 Released
  CodePoet Consulting is pleased to announce the immediate availability of uClibc 0.9.16. This release adds full support (including a native shared library loader) for the CRIS architecture, contributed by Tobias Anderberg. Stefan Allius contributed a number of patches to fix the initialization order for shared library global constructors and destructors as well as a large number of SuperH fixes and cleanups. uClibc now compiles with newer versions of gcc (i.e. RedHat 8.0). Thanks to Christian Michon, uClibc no longer requires perl to compile. Steven J. Hill fixed dlopen for mips. Several problems with pty and tty handling were fixed. Manuel Novoa added new support for an /etc/TZ file to globally set the system timezone, and fixed up a number of remaining wide char issues. Manuel is still hard at work on bringing full locale support (optional of course) to uClibc. And of course, this release includes the usual pile of bug fixes. Many thanks for the large number of patches and fixes that were contributed!

  Erik and Manuel have been working on a document describing some of the differences between uClibc and glibc. It's not yet 100% complete, and it hasn't been nicely formatted yet. But it contains a lot of helpful information and is worth a look.

  And finally, the the old uClibc configuration system has been completely removed (and there was much rejoicing). It was replaced with an entirely new system based on LinuxKernelConf, which has since been included into Linux 2.5.45, so it looks like Erik made the right choice. Of course, those who have existing build systems using uClibc will need to make a few changes... We think the change is worth it.

  As usual, the Changelog and source code for this release are available here. You might want to download uClibc from the closest kernel.org mirror site. Just pick the closest mirror site, and then go to http://www.XX.kernel.org/pub/linux/libs/uclibc/ to download uClibc, where XX is your two letter country code.

  Updated gcc-3.2 and gcc-2.95 toolchains will be released shortly.

- 16 September 2002, gcc-3.2 and gcc-2.95 toolchains released
  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 STLport standard C++ library.

  This toolchain should make it easy for anyone to build uClibc based applications. Source code can be downloaded here. 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).

- 27 August 2002, uClibc 0.9.15 Released
  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....

  The Changelog and source code for this release are available here.

  Have fun!

- 12 August 2002, uClibc 0.9.14 Released
  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.

  The Changelog and source code for this release are available here.

  Have fun!

- 12 August 2002, Native uClibc/gcc-3.1.1 toolchain released
  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.

  This toolchain should make it easy for anyone to build uClibc based applications. Source code can be downloaded here. 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...

- 9 August 2002, uClibc now mirrored on kernel.org!
  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 kernel.org mirror sites. Just pick the closest mirror site, and then go to "/pub/linux/libs/uclibc/" to download uClibc. Just pick the closest mirror site, and then go to http://www.XX.kernel.org/pub/linux/libs/uclibc/ to download the latest uClibc release from a nice fast system.

- 9 August 2002, uClibc 0.9.13 Released
  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().

  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 lot of work done to make uClibc a cleaner, more capable, library. Most applications now compile and run without any trouble.

  The Changelog and source code for this release are available here.

  Have fun!

- 11 July 2002, Native uClibc toolchains updated
  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.

  These toolchains should make it easy to anyone to build uClibc based applications. Source code can be downloaded here. 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...

- 20 June 2002, uClibc 0.9.12 Released
  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 much 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!

  The Changelog and source code for this release are available here.

- 28 May 2002, Native uClibc/gcc-3.1 toolchain
  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 here. 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.

- 10 April 2002, uClibc 0.9.11 Released
  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 working applications list .

  The Changelog and source code for this release are available here.

- 10 April 2002, Native uClibc/gcc-3.0.4 toolchain
  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 here.

  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.

- 21 March 2002, uClibc 0.9.10 Released!
  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.

  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.

  The Changelog and Source code for this release are available here.

- 4 February 2002, uClibc 0.9.9 Released!
  CodePoet Consulting is pleased to announce the immediate availability of uClibc 0.9.9. With this release, just about everything we have tested now compiles and runs. 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 not working list. Most applications on the not working list 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.

  The Changelog and Source code for this release are available here.

  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...

  Have Fun!

- 22 December 2001, uClibc 0.9.8 Released!
  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.

  The source code for this release is available here.

- 26 November 2001, powerpc shared libraries fully working
  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.

- 14 November 2001, m68 compiles again, Large file support working
  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.

  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.

- 12 November 2001, powerpc shared lib support
  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!

- 7 November 2001, uClibc application list
  uClibc now has a list of applications that are known to work. If you have any applications to add to the list, submissions are welcome!

- 18 October 2001, buildroot uClibc example system
  Those wanting an easy way to test out uClibc and give it a test drive can download and compile buildroot. This is a nifty buildsystem that will automagically download and build a User-Mode Linux 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 Tuxscreen Project is using a slightly adjusted variant of the buildroot system 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.

- 11 October 2001, v850 architecture support
  Miles Bader has contributed support for the v850 architecture.

- 25 Spetember 2001, header files updated
  uClibc's header files are now in sync with glibc 2.2.4, allowing better standards compliance, better portibility, and better C++ support.

- 4 July 2001, ARM shared library support
  uClibc now has full shared library support on ARM.

- 9 May 2001, libm added
  uClibc now has a very complete math library.

- 9 May 2001, ld.so added
  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.

- 15 March 2001, powerpc port added
  David Schleef contributed a powerpc port, which is now in CVS.

- 19 February 2001, SH port added
  Jean-Yves Avenard contributed an SH port. See his email with the initial patch here.

- 16 January 2001, uClibc as a shared library
  As if January 16, uClibc can now be used (at least on x86) as a shared library. See the email announcing this achievement.

- 11 January 2001, gcc wrapper added
  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.

- 3 January 2001, uClibc now has a web page
  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 usable.
