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:

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.
