This directory contains the sources of the GNU C Library.

See the file "version.h" for what release version you have.

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.

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[4567]86-*-gnu.

When working with Linux kernels, this version of the GNU C Library

requires Linux kernel version 3.2 or later.

Also note that the shared version of the libgcc_s library must be

installed for the pthread library to work correctly.

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

	aarch64*-*-linux-gnu

	alpha*-*-linux-gnu

	arm-*-linux-gnueabi

	hppa-*-linux-gnu

	i[4567]86-*-linux-gnu

	x86_64-*-linux-gnu	Can build either x86_64 or x32

	ia64-*-linux-gnu

	m68k-*-linux-gnu

	microblaze*-*-linux-gnu

	mips-*-linux-gnu

	mips64-*-linux-gnu

	powerpc-*-linux-gnu	Hardware or software floating point, BE only.

	powerpc64*-*-linux-gnu	Big-endian and little-endian.

	s390-*-linux-gnu

	s390x-*-linux-gnu

	riscv64-*-linux-gnu

	sh[34]-*-linux-gnu

	sparc*-*-linux-gnu

	sparc64*-*-linux-gnu

If you are interested in doing a port, please contact the glibc

maintainers; see http://www.gnu.org/software/libc/ 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 http://www.gnu.org/software/libc/.

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.

Please see http://www.gnu.org/software/libc/bugs.html 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.  License copyright years may be

listed using range notation, e.g., 1996-2015, indicating that every year in

the range, inclusive, is a copyrightable year that would otherwise be listed

individually.
