应该是最先使用glibc 2.4的发行版.

glibc 2.4发布了，这个版本的glibc正式采用NTPL作为pthread实现，并且要求2.6以上的内核。

GNU C Library version 2.4 release

* From: Roland McGrath <roland at gnu dot org>
* To: info-gnu at gnu dot org
* Cc: libc-announce at sources dot redhat dot com, libc-alpha at sources dot redhat dot com
* Date: Mon, 6 Mar 2006 04:46:48 -0800 (PST)
* Subject: GNU C Library version 2.4 release

Version 2.4 of the GNU C Library is now available for download at:

http://ftp.gnu.org/gnu/glibc/
ftp://ftp.gnu.org/gnu/glibc/
ftp://sources.redhat.com/pub/glibc/releases/

Please see http://www.gnu.org/order/ftp.html and
http://sources.redhat.com/mirrors.html for mirror sites around the world.

Version 2.4 is the first release after a long period of development, and
introduces changes to the API and a new ABI for all configurations. The
NEWS file in the distribution lists major additions, and there are many
smaller changes along with innumerable bug fixes. This code has been
tested and deployed in new production systems, but should still be
considered somewhat experimental. The stable 2.3 release series
continues to be maintained, and implements a widely-deployed ABI.
Version 2.3.6 is available, and we will release 2.3.7 with more bug fixes.

Once you install version 2.4, most program binaries you compile will not
be able to run on older installations based on 2.3.6 or earlier versions.
Existing dynamically-linked program binaries built using older glibc
versions should continue to work if they make proper use of the library
interfaces as specified.

While the code in this release has received substantial testing and is
going into new production systems, we are already aware of a few issues
and have a backlog of problem reports awaiting investigation. We believe
this release marks a point of decent stability and substantial improvement
over version 2.3, and its ABI will remain stable for later 2.4 releases.
We hope that making this release now will lead to more strenuous testing.
We anticipate a 2.4.1 release in the not too distant future to tie up
loose ends and fold in more fixes and improvements made after the initial
deployments of systems based on the 2.4 ABI.

Be advised that updating the C library is no trivial task and it is very
easy to damage one's system. Unless you are participating in the
development and maintenance of the C library, you should use a binary
distribution instead. The code in this release has already been built
and tested by maintainers of binary distributions basing their systems
on it. If you are not already using a system based on the version 2.4
ABI, then you may wreak havoc by attempting to install this version.

We recommend using GCC 4.1 to build this version of the GNU C Library.
For the S/390 and 32-bit PowerPC architectures, GCC 4.1 is required.
For other architectures, GCC 3.4 or later will work but 4.0 and 4.1 are better.

The following files are available:

Version 2.4

* More overflow detection functions.

* New iconv converters for IBM1025, IBM1122, IBM1137, IBM1153,
IBM1154, IBM1155, IBM1156, IBM1157, and IBM1158 contributed by Jiro Sekiba.

More converters for IBM803, IBM901, IBM902, IBM921, IBM1008, IBM1097,
IBM1112, IBM1123, IBM1130, IBM1140, IBM1141, IBM1142, IBM1143, IBM1144,
IBM1145, IBM1146, IBM1147, IBM1148, IBM1149, IBM1166, IBM1167, IBM4517,
IBM4899, IBM4909, IBM4971, IBM5347, IBM9030, IBM9066, IBM9448, IBM12712,
IBM16804, IBM1364, IBM1371, IBM1388, IBM1390, and IBM1399 contributed
by Masahide Washizawa.

* It is now possible to install audit libraries for the dynamic linker using
LD_AUDIT. Implemented by Ulrich Drepper.

* The LinuxThreads add-on, providing pthreads on Linux 2.4 kernels, is no
longer supported. The new NPTL implementation requires Linux 2.6 kernels.
For a libc and libpthread that works well on Linux 2.4 kernels, we
recommend using the stable 2.3 branch.

* The new function open_wmemstream acts like open_memstream,
but uses a wchar_t wide character buffer.

* The new function ppoll is an improved version of poll, similar to pselect.

* New interfaces: fdopendir, openat, fstatat, fchmodat, fchownat,
futimesat, faccessat, mkdirat, mkfifoat, mknodat,
renameat, unlinkat, linkat, symlinkat, readlinkat.

* New Linux kernel system calls: unshare,
inotify_init, inotify_add_watch, inotify_rm_watch.

* The euidaccess function is now also known by the alias eaccess,
for compatibility with some other systems.

* Timezone data updated to 2006b version.

不错
有几点要注意
使用了glibc 2.4编译出来的大多数程序不能在使用glibc 2.3的系统中运行，反过来应该是可以的
还有此版本推荐使用gcc 4.1来编译
此版本不再支持与2.4内核配套的LinuxThreads线程库，所以一定要使用2.6内核才能用这个版本

使用了glibc 2.4编译出来的大多数程序不能在使用glibc 2.3的系统中运行，反过来应该是可以的
还有此版本推荐使用gcc 4.1来编译
此版本不再支持与2.4内核配套的LinuxThreads线程库，所以一定要使用2.6内核才能用这个版本

如果要升级有没有什么升级建议。我上次把gcc升到4.1，也许升得有问题，系统中很多程序都用不料了。后来只好重新安装，一切使用“保守”配置，gcc只敢用3.4.5了。对于这些系统程序现在有点不敢胡乱动了。
这样下来感觉整个系统速度有点慢。

younker

glibc升级应该问题不大， 我已经升级到gcc4.1了， 正在merge glibc 2.4.

fei

最好不要自己用gentoo不推荐的ebuild.只用x86最多用~x86

vliqi

我现在正在从stage1编译，用的是gcc4.1和glibc2.4,但愿别闹出什么乱子。我现在系统上没有gcc3

quhw

好像还有不少包gcc 4.1编译不过去的。

正在用gcc-4.1 + glibc-2.4，感觉没什么问题。

还有，自从用了gcc-4.1以后，scim的qt immodule就不能用了。

younker

merge成功了， 没有发现问题。

younker

发布注意事项1
如果你曾经merge了ruby，那么在glibc升级到2.4之后， 你要重新merge ruby， 否则koffice等软件在编译的错误会出现错误。
