Configuring and compiling GNU Libc
==================================
-GNU libc can be compiled in the source directory, but we strongly advise
-building it in a separate build directory. For example, if you have
-unpacked the glibc sources in `/src/gnu/glibc-2.3', create a directory
+GNU libc cannot be compiled in the source directory. You must build it
+in a separate build directory. For example, if you have unpacked the
+glibc sources in `/src/gnu/glibc-2.4', create a directory
`/src/gnu/glibc-build' to put the object files in. This allows
-removing the whole build directory in case an error occurs, which is the
-safest way to get a fresh start and should always be done.
+removing the whole build directory in case an error occurs, which is
+the safest way to get a fresh start and should always be done.
From your object directory, run the shell script `configure' located
at the top level of the source tree. In the scenario above, you'd type
- $ ../glibc-2.3/configure ARGS...
+ $ ../glibc-2.4/configure ARGS...
- Please note that even if you're building in a separate build
+ Please note that even though you're building in a separate build
directory, the compilation needs to modify a few files in the source
directory, especially some files in the manual subdirectory.
-`configure' takes many options, but you can get away with knowing only
-two: `--prefix' and `--enable-add-ons'. The `--prefix' option tells
-`configure' where you want glibc installed. This defaults to
-`/usr/local'. The `--enable-add-ons' option tells `configure' to use
-all the add-on bundles it finds in the source directory. Since
-important functionality is provided in add-ons, you should always
-specify this option.
+`configure' takes many options, but the only one that is usually
+mandatory is `--prefix'. This option tells `configure' where you want
+glibc installed. This defaults to `/usr/local', but the normal setting
+to install as the standard system library is `--prefix=/usr' for
+GNU/Linux systems and `--prefix=' (an empty prefix) for GNU/Hurd
+systems.
It may also be useful to set the CC and CFLAGS variables in the
environment when running `configure'. CC selects the C compiler that
ones found in `/usr/include'.
`--enable-add-ons[=LIST]'
- Enable add-on packages in your source tree. If this option is

specified with no list, it enables all the add-on packages it
- finds. If you do not wish to use some add-on packages that you

- add-ons that you _do_ want used, like this: `--enable-add-ons=nptl'

+ You may specify an explicit list of add-ons to use in LIST,
+ separated by spaces or commas (if you use spaces, remember to
+ quote them from the shell). Each add-on in LIST can be an
+ absolute directory name or can be a directory name relative to the
+ main source directory, or relative to the build directory (that
+ is, the current working directory). For example,
+ `--enable-add-ons=nptl,../glibc-libidn-2.4'.
`--enable-kernel=VERSION'
This option is currently only useful on GNU/Linux systems. The

Those indicate that something is seriously wrong.

-Supported Configurations
-========================
-
-The GNU C Library currently supports configurations that match the
-following patterns:
-
- alpha*-*-linux
- arm-*-linux
- cris-*-linux
- hppa-*-linux
- iX86-*-gnu
- iX86-*-linux
- ia64-*-linux
- m68k-*-linux
- mips*-*-linux
- powerpc-*-linux
- s390-*-linux
- s390x-*-linux
- sparc-*-linux
- sparc64-*-linux
- x86_64-*-linux
-
- Former releases of this library (version 2.1 and/or 2.0) used to run
-on the following configurations:
-
- arm-*-linuxaout
- arm-*-none
-
- Very early releases (version 1.09.1 and perhaps earlier versions)
-used to run on the following configurations:
-
- alpha-dec-osf1
- alpha-*-linuxecoff
- iX86-*-bsd4.3
- iX86-*-isc2.2
- iX86-*-isc3.N
- iX86-*-sco3.2
- iX86-*-sco3.2v4
- iX86-*-sysv
- iX86-*-sysv4
- iX86-force_cpu386-none
- iX86-sequent-bsd
- i960-nindy960-none
- m68k-hp-bsd4.3
- m68k-mvme135-none
- m68k-mvme136-none
- m68k-sony-newsos3
- m68k-sony-newsos4
- m68k-sun-sunos4.N
- mips-dec-ultrix4.N
- mips-sgi-irix4.N
- sparc-sun-solaris2.N
- sparc-sun-sunos4.N
-
- Since no one has volunteered to test and fix these configurations,
-they are not supported at the moment. They probably don't compile;
-they definitely don't work anymore. Porting the library is not hard.
-If you are interested in doing a port, please contact the glibc
-maintainers. Start at `http://www.gnu.org/software/libc/' and read the
-references there on how to go about getting involved and contacting the
-developers.
-
- Valid cases of `iX86' include `i386', `i486', `i586', and `i686'.
-All of those configurations produce a library that can run on this
-processor and newer processors. The GCC compiler by default generates
-code that's optimized for the machine it's configured for and will use
-the instructions available on that machine. For example if your GCC is
-configured for `i686', gcc will optimize for `i686' and might issue
-some `i686' specific instructions. To generate code for other models,
-you have to configure for that model and give GCC the appropriate
-`-march=' and `-mcpu=' compiler switches via CFLAGS.
-
Specific advice for GNU/Linux systems
=====================================
-This directory contains the version 2.3.4 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
- powerpc64-*-linux-gnu Linux-2.4.19+ on 64-bit PowerPC systems
- sparc-*-linux-gnu Linux-2.x on SPARC
- sparc64-*-linux-gnu Linux-2.x on UltraSPARC 64-bit
- arm-*-none ARM standalone systems
- arm-*-linux Linux-2.x on ARM
- arm-*-linuxaout Linux-2.x on ARM using a.out binaries

- sh-*-linux-gnu Linux-2.x on Super Hitachi
- x86-64-*-linux-gnu Linux-2.4+ on x86-64
-
-Past releases of this library ran on a variety of configurations that are
-no longer supported. Porting the library is not hard. If you are
-interested in doing a port, please contact the glibc maintainers;
-see http://www.gnu.org/software/libc/ for more information.
-
-There are some 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.
+This directory contains the version 2.4 release of the GNU C Library.
+
+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.
+
+Version 2.4 is the first release after a long period of development, and
+introduces changes to the API and a new ABI for all configurations. It
+has been tested and deployed in new production systems, but should still
+be considered somewhat experimental. The stable 2.3 release series
+continues to be maintained, and implements a widely-deployed ABI.
+Version 2.3.6 is available, and we will release 2.3.7 with more bug fixes.
+
+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.

+GNU libc cannot be compiled in the source directory. You must build
+it in a separate build directory. For example, if you have unpacked
+the glibc sources in @file{/src/gnu/glibc-2.4}, create a directory

+removing the whole build directory in case an error occurs, which is
+the safest way to get a fresh start and should always be done.
From your object directory, run the shell script @file{configure} located
at the top level of the source tree. In the scenario above, you'd type
@smallexample
-$ ../glibc-2.3/configure @var{args@dots{}}

-@code{configure} takes many options, but you can get away with knowing
-only two: @samp{--prefix} and @samp{--enable-add-ons}. The
-@code{--prefix} option tells @code{configure} where you want glibc
-installed. This defaults to @file{/usr/local}. The

+@code{configure} takes many options, but the only one that is usually
+mandatory is @samp{--prefix}. This option tells @code{configure}
+where you want glibc installed. This defaults to @file{/usr/local},
+but the normal setting to install as the standard system library is
+@samp{--prefix=/usr} for GNU/Linux systems and @samp{--prefix=} (an
+empty prefix) for GNU/Hurd systems.
It may also be useful to set the @var{CC} and @var{CFLAGS} variables in
the environment when running @code{configure}. @var{CC} selects the C
@file{/usr/include}.
@item --enable-add-ons[=@var{list}]
-Enable add-on packages in your source tree. If this option is specified
-with no list, it enables all the add-on packages it finds. If you do
-not wish to use some add-on packages that you have present in your source
-tree, give this option a list of the add-ons that you @emph{do} want
-used, like this: @samp{--enable-add-ons=nptl}
+Specify add-on packages to include in the build. If this option is
+specified with no list, it enables all the add-on packages it finds in
+the main source directory; this is the default behavior. You may
+specify an explicit list of add-ons to use in @var{list}, separated by
+spaces or commas (if you use spaces, remember to quote them from the
+shell). Each add-on in @var{list} can be an absolute directory name
+or can be a directory name relative to the main source directory, or
+relative to the build directory (that is, the current working directory).
+For example, @samp{--enable-add-ons=nptl,../glibc-libidn-2.4}.
@item --enable-kernel=@var{version}
This option is currently only useful on GNU/Linux systems. The
@code{make} but isn't. Look for error messages from @code{make}
containing @samp{***}. Those indicate that something is seriously wrong.
-The compilation process can take several hours. Expect at least two
-hours for the default configuration on i586 for GNU/Linux. For Hurd,
-times are much longer. Some complex modules may take a very long time
-to compile, as much as several minutes on slower machines. Do not
-panic if the compiler appears to hang.

-@node Supported Configurations
-@appendixsec Supported Configurations
-@cindex configurations, all supported
-
-The GNU C Library currently supports configurations that match the
-following patterns:
-
-@smallexample
-alpha@var{*}-@var{*}-linux
-arm-@var{*}-linux
-cris-@var{*}-linux
-hppa-@var{*}-linux
-i@var{x}86-@var{*}-gnu
-i@var{x}86-@var{*}-linux

-s390x-@var{*}-linux
-sparc-@var{*}-linux
-sparc64-@var{*}-linux
-x86_64-@var{*}-linux
-@end smallexample
-
-Former releases of this library (version 2.1 and/or 2.0) used to run on
-the following configurations:
-
-@smallexample
-arm-@var{*}-linuxaout
-arm-@var{*}-none
-@end smallexample
-
-Very early releases (version 1.09.1 and perhaps earlier versions) used
-to run on the following configurations:
-
-@smallexample
-alpha-dec-osf1
-alpha-@var{*}-linuxecoff
-i@var{x}86-@var{*}-bsd4.3
-i@var{x}86-@var{*}-isc2.2
-i@var{x}86-@var{*}-isc3.@var{n}
-i@var{x}86-@var{*}-sco3.2
-i@var{x}86-@var{*}-sco3.2v4
-i@var{x}86-@var{*}-sysv
-i@var{x}86-@var{*}-sysv4
-i@var{x}86-force_cpu386-none
-i@var{x}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.@var{n}
-mips-dec-ultrix4.@var{n}
-mips-sgi-irix4.@var{n}
-sparc-sun-solaris2.@var{n}
-sparc-sun-sunos4.@var{n}
-@end smallexample
-
-Since no one has volunteered to test and fix these configurations,
-they are not supported at the moment. They probably don't compile;
-they definitely don't work anymore. Porting the library is not hard.
-If you are interested in doing a port, please contact the glibc
-maintainers. Start at @url{http://www.gnu.org/software/libc/} and
-read the references there on how to go about getting involved and
-contacting the developers.
-
-Valid cases of @samp{i@var{x}86} include @samp{i386}, @samp{i486},
-@samp{i586}, and @samp{i686}. All of those configurations produce a
-library that can run on this processor and newer processors. The GCC
-compiler by default generates code that's optimized for the machine it's
-configured for and will use the instructions available on that machine.
-For example if your GCC is configured for @samp{i686}, gcc will optimize
-for @samp{i686} and might issue some @samp{i686} specific instructions.
-To generate code for other models, you have to configure for that model
-and give GCC the appropriate @samp{-march=} and @samp{-mcpu=} compiler
-switches via @var{CFLAGS}.
