This pair of announcements from Erik Andersen covers two updates to uClibc (version 0.9.13 followed by a quick bug fix), news of a native uClibc/gcc-3.1.1 toolchain, and the exciting announcement that uClibc is now available from the kernel.org mirrors . . .

uClibc Version 0.9.14

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 uClibc 0.9.14 release can be obtained here or here. The Changelog for this release is here or here.

In addition, a native uClibc/gcc-3.1.1 toolchain has now been released. 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. Source to build a uClibc native toolchain can be obtained here.

uClibc Version 0.9.13

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. Also 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, and more capable library.

Another exciting piece of news is that 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). Just pick the closest kernel.org mirror site, and uClibc should be available under “/pub/linux/libs/uclibc/”. For example, to download from a kernel.org mirror site in the USA, you can go to this link. For other countries, change 'us' to your 2 letter country code.

The uClibc 0.9.13 release can be obtained here or here. The Changelog for this release is here or here.

The native uClibc/gcc toolchains have been updated and will be released in the next several days.
