This directory contains the version 2.1.90 release of the GNU C Library.
Many bugs have been fixed since the last release.
Some bugs surely remain.
As of this release, the GNU C library is known to run on the following
configurations:
*-*-gnu GNU Hurd
i[3456]86-*-linux-gnu Linux-2.x on Intel
m68k-*-linux-gnu Linux-2.x on Motorola 680x0
alpha-*-linux-gnu Linux-2.x on DEC Alpha
powerpc-*-linux-gnu Linux and MkLinux on PowerPC systems
sparc-*-linux-gnu Linux-2.x on SPARC
sparc64-*-linux-gnu Linux-2.x on UltraSPARC
arm-*-none ARM standalone systems
arm-*-linux Linux-2.x on ARM
arm-*-linuxaout Linux-2.x on ARM using a.out binaries
Former releases of this library (version 1.09.1 and perhaps earlier
versions) used to run on the following configurations:
alpha-dec-osf1
i[3456]86-*-bsd4.3
i[3456]86-*-isc2.2
i[3456]86-*-isc3
i[3456]86-*-sco3.2
i[3456]86-*-sco3.2v4
i[3456]86-*-sysv
i[3456]86-*-sysv4
i[3456]86-force_cpu386-none
i[3456]86-sequent-bsd
i960-nindy960-none
m68k-hp-bsd4.3
m68k-mvme135-none
m68k-mvme136-none
m68k-sony-newsos3
m68k-sony-newsos4
m68k-sun-sunos4
mips-dec-ultrix4
mips-sgi-irix4
sparc-sun-solaris2
sparc-sun-sunos4
Since no one has volunteered to test and fix the above configurations,
these are not supported at the moment. It's expected that these don't
work anymore. Porting the library is not hard. If you are interested
in doing a port, please contact the glibc maintainers by sending
electronic mail to <bug-glibc@gnu.org>.
The GNU C library now includes Michael Glad's Ultra Fast Crypt, which
provides the Unix `crypt' function, plus some other entry points.
Because of the United States export restriction on DES
implementations, we are distributing this code separately from the
rest of the C library. There is an extra distribution tar file just
for crypt; it is called `glibc-crypt-2.1.90.tar.gz'. You can just
unpack the crypt distribution along with the rest of the C library and
build; you can also build the library without getting crypt. Users
outside the USA can get the crypt distribution via anonymous FTP from
ftp.gwdg.de [134.76.11.100] in the directory pub/linux/glibc, or
another archive site outside the USA. Archive maintainers are
encouraged to copy this distribution to their archives outside the
USA. Please get it from ftp.gwdg.de; transferring this distribution
from ftp.gnu.org (or any other site in the USA) to a site outside the
USA is in violation of US export laws.
Beside the separate crypt tar file there are some more add-ons which can be
used together with GNU libc. They are designed in a way to ease the
installation by integrating them in the libc source tree. Simply get the
add-ons you need and use the --enable-add-ons option of the `configure'
script to tell where the add-ons are found. Please read the FAQ file for
more details.
See the file INSTALL to find out how to configure, build, install, and port
the GNU C library. You might also consider reading the WWW pages for the
GNU libc at http://www.gnu.org/software/libc/libc.html.
The GNU C Library is 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.
Please send comments on the manual to <bug-glibc-manual@gnu.org>, and
not to the library bug-reporting address.
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.
We prefer to get bug reports sent using the `glibcbug' shell script which
is installed together with the rest of the GNU libc to <bugs@gnu.org>.
Simply run this shell script and fill in the information. Nevertheless
you can still send bug reports to <bug-glibc@gnu.org> as normal electronic
mails.
The GNU C Library is free software. See the file COPYING.LIB for copying
conditions.
