| 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. The current |
| GNU/Hurd support requires out-of-tree patches that will eventually be |
| incorporated into an official GNU C Library release. |
| |
| 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: |

| hppa-*-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. |
