- <li> <b>9 September 2003, uClibc 0.9.21 Released</b>
- <br>
-
- 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.
-
- <p>
-
- 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.
-
- <p>
-
- 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 <a
- href="http://ltp.sourceforge.net/"> Linux Test Project test suite</a> and
- give uClibc some abuse. We are not yet perfect, but we are getting pretty
- darn close.
-
- <p>
-
- 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...

- <li> <b>30 June 2003, uClibc 0.9.20 Released</b>
- <br>
-
- 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.
- <p>
-
- 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.
- <p>
-
- 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....

- <a href="http://www.kernel.org/pub/linux/libs/uclibc/root_fs_mipsel.bz2">mips</a>,
- 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.
- <p>
-
- 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. You can loop mount and then
- chroot into them, you can boot into them 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.
-
- <p> If you would like to build your own custom uClibc system, you can
- use <a href="/cgi-bin/cvsweb/buildroot/">buildroot</a>, which is
- how the uClibc development systems were created.

- <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.

- 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

-
- <p>
- <li> <b>12 February 2003, uClibc 0.9.18 Released</b>
- <br>
-
- 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...)

-
- <p>
- <li> <b>25 January 2003, uClibc 0.9.17 Released</b>
- <br>
-
- 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.
-
- <p>
-
- This release also fixes <em>lots and lots</em> 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!
-
- <p>
-
- Unfortunately, this release is not binary compatible with earlier uClibc
- releases. As noted as item 3 <a href="downloads/Glibc_vs_uClibc_Differences.txt">here</a>,
- 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 <em>may</em>
- need additional updates. Sorry about that, but it had to be done.

-
- <p>
- <li> <b>25 January 2003, dev system updates, arm image released</b>
- <br>
-
- 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 <a href="http://www.kernel.org/pub/linux/libs/uclibc/root_fs_i386.bz2">
- i386 development system image</a>, the
- <a href="http://www.kernel.org/pub/linux/libs/uclibc/root_fs_powerpc.bz2">
- powerpc development system image</a>, and I am also releasing
- upon an unsuspecting world the brand new
- <a href="http://www.kernel.org/pub/linux/libs/uclibc/root_fs_arm.bz2">
- arm development system image</a>!
- Have fun!
- <p>
-
- All three development system images were compiled and built using the stock
- <a href="/cgi-bin/cvsweb/buildroot/">buildroot</a> 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.
-
- <p>
- Oh, and I have also have updated the uClibc/gcc toolchain builders, so
- if you just want a simple uClibc/gcc toolchain,
- <a href="/cgi-bin/cvsweb/toolchain/">one of these should work for you.</a>
- <p>
-
-
- <p>
- <li> <b>10 January 2003, dev system updates, powerpc image released</b>
- <br>
-
- 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 <a href="http://www.kernel.org/pub/linux/libs/uclibc/root_fs_i386.bz2">
- i386 development system image</a> to fix these problems.
- Also, the <a href="http://www.kernel.org/pub/linux/libs/uclibc/root_fs_powerpc.bz2">
- powerpc development system image</a> has finally finished compiling
- and is now released upon an unsuspecting world. Have fun!
- <p>
-
-
- <p>
- <li> <b>9 January 2003, uClibc development system released</b>
- <br>
-
- CodePoet Consulting (i.e. Erik) has been working hard on <a
- href="/cgi-bin/cvsweb/buildroot/">buildroot</a> 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....
-
- <p>
-
- The <a href="http://www.kernel.org/pub/linux/libs/uclibc/root_fs_i386.bz2">
- uClibc development system is an 18MB bzip2 compressed ext2 filesystem</a>,
- 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... <EM>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.</EM>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:<PRE>
- bzcat root_fs_i386.bz2 | dd of=/dev/hdg1
- e2fsck -f /dev/hdg1
- resize2fs -p /dev/hdg1</PRE>
-
- 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.

-
- <p>
- <li> <b>8 November 2002, uClibc 0.9.16 Released</b>
- <br>
-
- 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!
- <p>
-
- Erik and Manuel have been working on a
- <a href="downloads/Glibc_vs_uClibc_Differences.txt">
- document describing some of the differences between uClibc and glibc.</a>
- 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.
- <p>
-
- 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 <a href="http://www.xs4all.nl/~zippel/lc/">LinuxKernelConf</a>,
- 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.

-
- <p>
- <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="/cgi-bin/cvsweb/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).

- 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....

- <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.

- <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="/cgi-bin/cvsweb/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...

-
- <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.
- Just pick the closest mirror site, and then go to
- <a href="http://www.kernel.org/pub/linux/libs/uclibc/">
- http://www.XX.kernel.org/pub/linux/libs/uclibc/</a> to download the latest
- uClibc release from a nice fast system.

- <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.

-
- <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.

- <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!

- 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.
- <a href="/cgi-bin/cvsweb/toolchain/">Source code can be downloaded 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><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>

-
-
- <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).
- <a href="/cgi-bin/cvsweb/toolchain/">Source code can be downloaded here</a>.
- <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.

- <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="/cgi-bin/cvsweb/buildroot/">buildroot</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-&lt arch&gt. 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.
