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. - -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. - -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. - -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. - -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. - -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-2.5 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 - -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.
