交叉编译2.7 glibc的注意事项

This directory contains the version 2.7 release of the GNU C Library.

The GNU C Library is the standard system C library for all GNU systems,
and is an important part of what makes up a GNU system. It provides the
system API for all programs written in C and C-compatible languages such
as C++ and Objective C; the runtime facilities of other programming
languages use the C library to access the underlying operating system.
GNU系统的标准系统C库
GNU系统重要的组成部分
提供了系统的API，为所有用C或者兼容C的语言，例如C＋＋和面向对象C
其它语言使用C库runtime来访问底层的操作系统

In GNU/Linux systems, the C library works with the Linux kernel to
implement the operating system behavior seen by user applications.
In GNU/Hurd systems, it works with a microkernel and Hurd servers.
应用软件通过C库和系统内核一起实现操作系统的运作

The GNU C Library implements much of the POSIX.1 functionality in the
GNU/Hurd system, using configurations i[34567]86-*-gnu.

When working with Linux kernels, the GNU C Library version 2.4 is
intended primarily for use with Linux kernel version 2.6.0 and later.
We only support using the NPTL implementation of pthreads, which is now
the default configuration. Most of the C library will continue to work
on older Linux kernels and many programs will not require a 2.6 kernel
to run correctly. However, pthreads and related functionality will not
work at all on old kernels and we do not recommend using glibc 2.4 with
any Linux kernel prior to 2.6.
pthreads我们仅提供NPTL方面的支持，大多数C库不需要2.6的内核也可以工作。
不建议使用glibc2.4和2.6以前的内核

All Linux kernel versions prior to 2.6.16 are known to have some bugs that
may cause some of the tests related to pthreads in "make check" to fail.
If you see such problems, please try the test suite on the most recent
Linux kernel version that you can use, before pursuing those bugs further.
早于2.6.16版本的内核对于pthreads 支持不够完善，尽可能使用最新的内核

The old LinuxThreads add-on implementation of pthreads for older Linux
kernels is no longer supported, and we are not distributing it with this
release. Someone has volunteered to revive its maintenance unofficially
for at least a short time for the benefit of those using Linux kernels
older than 2.6, but a working version is not presently available. When
it is in working condition, we will make it available alongside future
glibc releases. LinuxThreads will not be supported.
旧式的LinuxThreads 插件不再提供支持，有志愿者进行非官方的支持工作，

The GNU C Library supports these configurations for using Linux kernels:

i[34567]86-*-linux-gnu
x86_64-*-linux-gnu
powerpc-*-linux-gnu
powerpc64-*-linux-gnu
s390-*-linux-gnu
s390x-*-linux-gnu
ia64-*-linux-gnu
sparc*-*-linux-gnu
sparc64*-*-linux-gnu

alpha*-*-linux-gnu Requires Linux 2.6.9 for NPTL
sh[34]-*-linux-gnu Requires Linux 2.6.11

The code for other CPU configurations supported by volunteers outside of
the core glibc maintenance effort is contained in the separate `ports'
add-on. You can find glibc-ports-2.7 distributed separately in the
same place where you got the main glibc distribution files.
Currently these configurations are known to work using the `ports' add-on:

arm-*-linux-gnu   Requires Linux 2.6.15 for NPTL, no SMP support
arm-*-linux-gnueabi Requires Linux 2.6.16-rc1 for NPTL, no SMP
mips-*-linux-gnu Requires Linux 2.6.12 for NPTL
mips64-*-linux-gnu Requires Linux 2.6.12 for NPTL
arm需要glibc-ports-2.7来支持glibc2.7的编译

The ports distribution also contains code for other configurations that
do not work or have not been maintained recently, but will be of use to
anyone trying to make a new configuration work. If you are interested
in doing a port, please contact the glibc maintainers; see
for more information.

See the file INSTALL to find out how to configure, build, and install
the GNU C Library. You might also consider reading the WWW pages for
the C library at .

The GNU C Library is (almost) completely documented by the Texinfo manual
found in the `manual/' subdirectory. The manual is still being updated
and contains some known errors and omissions; we regret that we do not
have the resources to work on the manual as much as we would like. For
corrections to the manual, please file a bug in the `manual' component,
following the bug-reporting instructions below. Please be sure to check
the manual in the current development sources to see if your problem has
already been corrected.

The file NOTES contains a description of the feature-test macros used
in the GNU C library, explaining how you can tell the library what
facilities you want it to make available.

Please see for bug reporting
information. We are now using the Bugzilla system to track all bug reports.
This web page gives detailed information on how to report bugs properly.

The GNU C Library is free software. See the file COPYING.LIB for copying
conditions, and LICENSES for notices about a few contributions that require
these additional notices to be distributed.
