-Library Maintenance
-*******************
-
-Adding New Functions
-====================
-
- The process of building the library is driven by the makefiles, which
-make heavy use of special features of GNU `make'. The makefiles are
-very complex, and you probably don't want to try to understand them.
-But what they do is fairly straightforward, and only requires that you
-define a few variables in the right places.
-
- The library sources are divided into subdirectories, grouped by
-topic.
-
- The `string' subdirectory has all the string-manipulation functions,
-`math' has all the mathematical functions, etc.
-
- Each subdirectory contains a simple makefile, called `Makefile',
-which defines a few `make' variables and then includes the global
-makefile `Rules' with a line like:
-
- include ../Rules
-
-The basic variables that a subdirectory makefile defines are:
-
-`subdir'
- The name of the subdirectory, for example `stdio'. This variable
- *must* be defined.
-
-`headers'
- The names of the header files in this section of the library, such
- as `stdio.h'.
-
-`routines'
-`aux'
- The names of the modules (source files) in this section of the
- library. These should be simple names, such as `strlen' (rather
- than complete file names, such as `strlen.c'). Use `routines' for
- modules that define functions in the library, and `aux' for
- auxiliary modules containing things like data definitions. But the
- values of `routines' and `aux' are just concatenated, so there
- really is no practical difference.
-
-`tests'
- The names of test programs for this section of the library. These
- should be simple names, such as `tester' (rather than complete file
- names, such as `tester.c'). `make tests' will build and run all
- the test programs. If a test program needs input, put the test
- data in a file called `TEST-PROGRAM.input'; it will be given to
- the test program on its standard input. If a test program wants
- to be run with arguments, put the arguments (all on a single line)
- in a file called `TEST-PROGRAM.args'. Test programs should exit
- with zero status when the test passes, and nonzero status when the
- test indicates a bug in the library or error in building.
-
-`others'
- The names of "other" programs associated with this section of the
- library. These are programs which are not tests per se, but are
- other small programs included with the library. They are built by
- `make others'.
-
-`install-lib'
-`install-data'
-`install'
- Files to be installed by `make install'. Files listed in
- `install-lib' are installed in the directory specified by `libdir'
- in `configparms' or `Makeconfig' (*note Installation::.). Files
- listed in `install-data' are installed in the directory specified
- by `datadir' in `configparms' or `Makeconfig'. Files listed in
- `install' are installed in the directory specified by `bindir' in
- `configparms' or `Makeconfig'.
-
-`distribute'
- Other files from this subdirectory which should be put into a
- distribution tar file. You need not list here the makefile itself
- or the source and header files listed in the other standard
- variables. Only define `distribute' if there are files used in an
- unusual way that should go into the distribution.
-
-`generated'
- Files which are generated by `Makefile' in this subdirectory.
- These files will be removed by `make clean', and they will never
- go into a distribution.
-
-`extra-objs'
- Extra object files which are built by `Makefile' in this
- subdirectory. This should be a list of file names like `foo.o';
- the files will actually be found in whatever directory object
- files are being built in. These files will be removed by
- `make clean'. This variable is used for secondary object files
- needed to build `others' or `tests'.
-
-Porting the GNU C Library
-=========================
-
- The GNU C library is written to be easily portable to a variety of
-machines and operating systems. Machine- and operating system-dependent
-functions are well separated to make it easy to add implementations for
-new machines or operating systems. This section describes the layout of
-the library source tree and explains the mechanisms used to select
-machine-dependent code to use.
-
- All the machine-dependent and operating system-dependent files in the
-library are in the subdirectory `sysdeps' under the top-level library
-source directory. This directory contains a hierarchy of
-subdirectories (*note Hierarchy Conventions::.).
-
- Each subdirectory of `sysdeps' contains source files for a
-particular machine or operating system, or for a class of machine or
-operating system (for example, systems by a particular vendor, or all
-machines that use IEEE 754 floating-point format). A configuration
-specifies an ordered list of these subdirectories. Each subdirectory
-implicitly appends its parent directory to the list. For example,
-specifying the list `unix/bsd/vax' is equivalent to specifying the list
-`unix/bsd/vax unix/bsd unix'. A subdirectory can also specify that it
-implies other subdirectories which are not directly above it in the
-directory hierarchy. If the file `Implies' exists in a subdirectory,
-it lists other subdirectories of `sysdeps' which are appended to the
-list, appearing after the subdirectory containing the `Implies' file.
-Lines in an `Implies' file that begin with a `#' character are ignored
-as comments. For example, `unix/bsd/Implies' contains:
- # BSD has Internet-related things.
- unix/inet
-
-and `unix/Implies' contains:
- posix
-
-So the final list is `unix/bsd/vax unix/bsd unix/inet unix posix'.
-
- `sysdeps' has a "special" subdirectory called `generic'. It is
-always implicitly appended to the list of subdirectories, so you
-needn't put it in an `Implies' file, and you should not create any
-subdirectories under it intended to be new specific categories.
-`generic' serves two purposes. First, the makefiles do not bother to
-look for a system-dependent version of a file that's not in `generic'.
-This means that any system-dependent source file must have an analogue
-in `generic', even if the routines defined by that file are not
-implemented on other platforms. Second. the `generic' version of a
-system-dependent file is used if the makefiles do not find a version
-specific to the system you're compiling for.
-
- If it is possible to implement the routines in a `generic' file in
-machine-independent C, using only other machine-independent functions in
-the C library, then you should do so. Otherwise, make them stubs. A
-"stub" function is a function which cannot be implemented on a
-particular machine or operating system. Stub functions always return an
-error, and set `errno' to `ENOSYS' (Function not implemented). *Note
-Error Reporting::. If you define a stub function, you must place the
-statement `stub_warning(FUNCTION)', where FUNCTION is the name of your
-function, after its definition; also, you must include the file
-`<stub-tag.h>' into your file. This causes the function to be listed
-in the installed `<gnu/stubs.h>', and makes GNU ld warn when the
-function is used.
-
- Some rare functions are only useful on specific systems and aren't
-defined at all on others; these do not appear anywhere in the
-system-independent source code or makefiles (including the `generic'
-directory), only in the system-dependent `Makefile' in the specific
-system's subdirectory.
-
- If you come across a file that is in one of the main source
-directories (`string', `stdio', etc.), and you want to write a machine-
-or operating system-dependent version of it, move the file into
-`sysdeps/generic' and write your new implementation in the appropriate
-system-specific subdirectory. Note that if a file is to be
-system-dependent, it *must not* appear in one of the main source
-directories.
-
- There are a few special files that may exist in each subdirectory of
-`sysdeps':
-
-`Makefile'
- A makefile for this machine or operating system, or class of
- machine or operating system. This file is included by the library
- makefile `Makerules', which is used by the top-level makefile and
- the subdirectory makefiles. It can change the variables set in the
- including makefile or add new rules. It can use GNU `make'
- conditional directives based on the variable `subdir' (see above)
- to select different sets of variables and rules for different
- sections of the library. It can also set the `make' variable
- `sysdep-routines', to specify extra modules to be included in the
- library. You should use `sysdep-routines' rather than adding
- modules to `routines' because the latter is used in determining
- what to distribute for each subdirectory of the main source tree.
-
- Each makefile in a subdirectory in the ordered list of
- subdirectories to be searched is included in order. Since several
- system-dependent makefiles may be included, each should append to
- `sysdep-routines' rather than simply setting it:
-
- sysdep-routines := $(sysdep-routines) foo bar
-
-`Subdirs'
- This file contains the names of new whole subdirectories under the
- top-level library source tree that should be included for this
- system. These subdirectories are treated just like the
- system-independent subdirectories in the library source tree, such
- as `stdio' and `math'.
-
- Use this when there are completely new sets of functions and header
- files that should go into the library for the system this
- subdirectory of `sysdeps' implements. For example,
- `sysdeps/unix/inet/Subdirs' contains `inet'; the `inet' directory
- contains various network-oriented operations which only make sense
- to put in the library on systems that support the Internet.
-
-`Dist'
- This file contains the names of files (relative to the
- subdirectory of `sysdeps' in which it appears) which should be
- included in the distribution. List any new files used by rules in
- the `Makefile' in the same directory, or header files used by the
- source files in that directory. You don't need to list files that
- are implementations (either C or assembly source) of routines
- whose names are given in the machine-independent makefiles in the
- main source tree.
-
-`configure'
- This file is a shell script fragment to be run at configuration
- time. The top-level `configure' script uses the shell `.' command
- to read the `configure' file in each system-dependent directory
- chosen, in order. The `configure' files are often generated from
- `configure.in' files using Autoconf.
-
- A system-dependent `configure' script will usually add things to
- the shell variables `DEFS' and `config_vars'; see the top-level
- `configure' script for details. The script can check for
- `--with-PACKAGE' options that were passed to the top-level
- `configure'. For an option `--with-PACKAGE=VALUE' `configure'
- sets the shell variable `with_PACKAGE' (with any dashes in PACKAGE
- converted to underscores) to VALUE; if the option is just
- `--with-PACKAGE' (no argument), then it sets `with_PACKAGE' to
- `yes'.
-
-`configure.in'
- This file is an Autoconf input fragment to be processed into the
- file `configure' in this subdirectory. *Note Introduction:
- (autoconf.info)Introduction, for a description of Autoconf. You
- should write either `configure' or `configure.in', but not both.
- The first line of `configure.in' should invoke the `m4' macro
- `GLIBC_PROVIDES'. This macro does several `AC_PROVIDE' calls for
- Autoconf macros which are used by the top-level `configure'
- script; without this, those macros might be invoked again
- unnecessarily by Autoconf.
-
- That is the general system for how system-dependencies are isolated.
-
-Layout of the `sysdeps' Directory Hierarchy
--------------------------------------------
-
- A GNU configuration name has three parts: the CPU type, the
-manufacturer's name, and the operating system. `configure' uses these
-to pick the list of system-dependent directories to look for. If the
-`--nfp' option is *not* passed to `configure', the directory
-`MACHINE/fpu' is also used. The operating system often has a "base
-operating system"; for example, if the operating system is `Linux', the
-base operating system is `unix/sysv'. The algorithm used to pick the
-list of directories is simple: `configure' makes a list of the base
-operating system, manufacturer, CPU type, and operating system, in that
-order. It then concatenates all these together with slashes in
-between, to produce a directory name; for example, the configuration
-`i686-linux-gnu' results in `unix/sysv/linux/i386/i686'. `configure'
-then tries removing each element of the list in turn, so
-`unix/sysv/linux' and `unix/sysv' are also tried, among others. Since
-the precise version number of the operating system is often not
-important, and it would be very inconvenient, for example, to have
-identical `irix6.2' and `irix6.3' directories, `configure' tries
-successively less specific operating system names by removing trailing
-suffixes starting with a period.
-
- As an example, here is the complete list of directories that would be
-tried for the configuration `i686-linux-gnu' (with the `crypt' and
-`linuxthreads' add-on):
-
- sysdeps/i386/elf
- crypt/sysdeps/unix
- linuxthreads/sysdeps/unix/sysv/linux
- linuxthreads/sysdeps/pthread
- linuxthreads/sysdeps/unix/sysv
- linuxthreads/sysdeps/unix
- linuxthreads/sysdeps/i386/i686
- linuxthreads/sysdeps/i386
- linuxthreads/sysdeps/pthread/no-cmpxchg
- sysdeps/unix/sysv/linux/i386
- sysdeps/unix/sysv/linux
- sysdeps/gnu
- sysdeps/unix/common
- sysdeps/unix/mman
- sysdeps/unix/inet
- sysdeps/unix/sysv/i386/i686
- sysdeps/unix/sysv/i386
- sysdeps/unix/sysv
- sysdeps/unix/i386
- sysdeps/unix
- sysdeps/posix
- sysdeps/i386/i686
- sysdeps/i386/i486
- sysdeps/libm-i387/i686
- sysdeps/i386/fpu
- sysdeps/libm-i387
- sysdeps/i386
- sysdeps/wordsize-32
- sysdeps/ieee754
- sysdeps/libm-ieee754
- sysdeps/generic
-
- Different machine architectures are conventionally subdirectories at
-the top level of the `sysdeps' directory tree. For example,
-`sysdeps/sparc' and `sysdeps/m68k'. These contain files specific to
-those machine architectures, but not specific to any particular
-operating system. There might be subdirectories for specializations of
-those architectures, such as `sysdeps/m68k/68020'. Code which is
-specific to the floating-point coprocessor used with a particular
-machine should go in `sysdeps/MACHINE/fpu'.
-
- There are a few directories at the top level of the `sysdeps'
-hierarchy that are not for particular machine architectures.
-
-`generic'
- As described above (*note Porting::.), this is the subdirectory
- that every configuration implicitly uses after all others.
-
-`ieee754'
- This directory is for code using the IEEE 754 floating-point
- format, where the C type `float' is IEEE 754 single-precision
- format, and `double' is IEEE 754 double-precision format. Usually
- this directory is referred to in the `Implies' file in a machine
- architecture-specific directory, such as `m68k/Implies'.
-
-`libm-ieee754'
- This directory contains an implementation of a mathematical library
- usable on platforms which use IEEE 754 conformant floating-point
- arithmetic.
-
-`libm-i387'
- This is a special case. Ideally the code should be in
- `sysdeps/i386/fpu' but for various reasons it is kept aside.
-
-`posix'
- This directory contains implementations of things in the library in
- terms of POSIX.1 functions. This includes some of the POSIX.1
- functions themselves. Of course, POSIX.1 cannot be completely
- implemented in terms of itself, so a configuration using just
- `posix' cannot be complete.
-
-`unix'
- This is the directory for Unix-like things. *Note Porting to
- Unix::. `unix' implies `posix'. There are some special-purpose
- subdirectories of `unix':
-
- `unix/common'
- This directory is for things common to both BSD and System V
- release 4. Both `unix/bsd' and `unix/sysv/sysv4' imply
- `unix/common'.
-
- `unix/inet'
- This directory is for `socket' and related functions on Unix
- systems. `unix/inet/Subdirs' enables the `inet' top-level
- subdirectory. `unix/common' implies `unix/inet'.
-
-`mach'
- This is the directory for things based on the Mach microkernel
- from CMU (including the GNU operating system). Other basic
- operating systems (VMS, for example) would have their own
- directories at the top level of the `sysdeps' hierarchy, parallel
- to `unix' and `mach'.
-
-Porting the GNU C Library to Unix Systems
------------------------------------------
-
- Most Unix systems are fundamentally very similar. There are
-variations between different machines, and variations in what
-facilities are provided by the kernel. But the interface to the
-operating system facilities is, for the most part, pretty uniform and
-simple.
-
- The code for Unix systems is in the directory `unix', at the top
-level of the `sysdeps' hierarchy. This directory contains
-subdirectories (and subdirectory trees) for various Unix variants.
-
- The functions which are system calls in most Unix systems are
-implemented in assembly code, which is generated automatically from
-specifications in files named `syscalls.list'. There are several such
-files, one in `sysdeps/unix' and others in its subdirectories. Some
-special system calls are implemented in files that are named with a
-suffix of `.S'; for example, `_exit.S'. Files ending in `.S' are run
-through the C preprocessor before being fed to the assembler.
-
- These files all use a set of macros that should be defined in
-`sysdep.h'. The `sysdep.h' file in `sysdeps/unix' partially defines
-them; a `sysdep.h' file in another directory must finish defining them
-for the particular machine and operating system variant. See
-`sysdeps/unix/sysdep.h' and the machine-specific `sysdep.h'
-implementations to see what these macros are and what they should do.
-
- The system-specific makefile for the `unix' directory
-(`sysdeps/unix/Makefile') gives rules to generate several files from
-the Unix system you are building the library on (which is assumed to be
-the target system you are building the library *for*). All the
-generated files are put in the directory where the object files are
-kept; they should not affect the source tree itself. The files
-generated are `ioctls.h', `errnos.h', `sys/param.h', and `errlist.c'
-(for the `stdio' section of the library).
+Installing the GNU C Library
+****************************
+
+ Installation of the GNU C library is relatively simple, but usually
+requires several GNU tools to be installed already.
+
+ Before you do anything else, you should read the file `FAQ' found at
+the top level of the source tree. This file answers common questions
+and describes problems you may experience with compilation and
+installation. It is updated more frequently than this manual.
+
+ To configure the GNU C library for your system, run the shell script
+`configure' with `sh'. You might use an argument which is the
+conventional GNU name for your system configuration--for example,
+`i486-pc-linux-gnu', for Linux running on i486. *Note Installation:
+(gcc.info)Installation, for a full description of standard GNU
+configuration names. If you omit the configuration name, `configure'
+will try to guess one for you by inspecting the system it is running
+on. It may or may not be able to come up with a guess, and the guess
+might be wrong. `configure' will tell you the canonical name of the
+chosen configuration before proceeding.
+
+ Here are some options that you should specify (if appropriate) when
+you run `configure':
+
+`--with-binutils=DIRECTORY'
+ Use the binutils (assembler and linker) in `DIRECTORY', not the
+ ones the C compiler would default to. You could use this option if
+ the default binutils on your system cannot deal with all the
+ constructs in the GNU C library. (`configure' will detect the
+ problem and suppress these constructs, so the library will still
+ be usable, but functionality may be lost--for example, you can not
+ build a shared libc with old binutils.)
+
+`--without-fp'
+`--nfp'
+ Use this option if your computer lacks hardware floating-point
+ support and your operating system does not emulate an FPU.
+
+`--prefix=DIRECTORY'
+ Install machine-independent data files in subdirectories of
+ `DIRECTORY'. (You can also set this in `configparms'; see below.)
+ The default is to install in `/usr/local'.
+
+`--exec-prefix=DIRECTORY'
+ Install the library and other machine-dependent files in
+ subdirectories of `DIRECTORY'. (You can also set this in
+ `configparms'; see below.) The default is to use <prefix>/bin and
+ <prefix>/sbin.
+
+`--enable-shared'
+`--disable-shared'
+ Enable or disable building of an ELF shared library on systems that
+ support it. The default is to build the shared library on systems
+ using ELF when the GNU `binutils' are available.
+
+`--enable-profile'
+`--disable-profile'
+ Enable or disable building of the profiled C library, `-lc_p'. The
+ default is to build the profiled library. You may wish to disable
+ it if you don't plan to do profiling, because it doubles the build
+ time of compiling just the unprofiled static library.
+
+`--enable-omitfp'
+ Enable building a highly-optimized but possibly undebuggable C
+ library. This causes the normal static and shared (if enabled) C
+ libraries to be compiled with maximal optimization, including the
+ `-fomit-frame-pointer' switch that makes debugging impossible on
+ many machines, and without debugging information (which makes the
+ binaries substantially smaller). An additional static library is
+ compiled with no optimization and full debugging information, and
+ installed as `-lc_g'.
+
+`--enable-add-ons[=LIST]'
+ Certain components of the C library are distributed separately
+ from the rest of the sources. In particular, the `crypt' function
+ and its friends are separated due to US export control
+ regulations, and the threading support code for Linux is
+ maintained separately. You can get these "add-on" packages from
+ the same place you got the libc sources. To use them, unpack them
+ into your source tree, and give `configure' the `--enable-add-ons'
+ option.
+
+ If you do not wish to use some add-on package that you have
+ present in your source tree, give this option a list of the
+ add-ons that you *do* want used, like this:
+ `--enable-add-ons=crypt,linuxthreads'
+
+`--with-headers=DIRECTORY'
+ Search only DIRECTORY and the C compiler's private directory for
+ header files not found in the libc sources. `/usr/include' will
+ not be searched if this option is given. On Linux, DIRECTORY
+ should be the kernel's private include directory (usually
+ `/usr/src/linux/include').
+
+ This option is primarily of use on a system where the headers in
+ `/usr/include' come from an older version of glibc. Conflicts can
+ occasionally happen in this case. Note that Linux libc5 qualifies
+ as an older version of glibc. You can also use this option if you
+ want to compile glibc with a newer set of kernel headers than the
+ ones found in `/usr/include'.
+
+ You should not build the library in the same directory as the
+sources, because there are bugs in `make clean'. Make a directory for
+the build, and run `configure' from that directory, like this:
+
+ mkdir linux
+ cd linux
+ ../configure
+
+`configure' looks for the sources in whatever directory you specified
+for finding `configure' itself. It does not matter where in the file
+system the source and build directories are--as long as you specify the
+source directory when you run `configure', you will get the proper
+results.
+
+ This feature lets you keep sources and binaries in different
+directories, and that makes it easy to build the library for several
+different machines from the same set of sources. Simply create a build
+directory for each target machine, and run `configure' in that
+directory specifying the target machine's configuration name.
+
+ The library has a number of special-purpose configuration parameters.
+These are defined in the file `configparms'; see the comments in that
+file for the details. To change them, copy `configparms' into your
+build directory and modify it as appropriate for your system.
+`configure' will not notice your modifications if you change the file
+in the source directory.
+
+ It is easy to configure the GNU C library for cross-compilation by
+setting a few variables in `configparms'. Set `CC' to the
+cross-compiler for the target you configured the library for; it is
+important to use this same `CC' value when running `configure', like
+this: `CC=TARGET-gcc configure TARGET'. Set `BUILD_CC' to the compiler
+to use for for programs run on the build system as part of compiling
+the library. You may need to set `AR' and `RANLIB' to cross-compiling
+versions of `ar' and `ranlib' if the native tools are not configured to
+work with object files for the target you configured for.
+
+ Some of the machine-dependent code for some machines uses extensions
+in the GNU C compiler, so you may need to compile the library with GCC.
+(In fact, all of the existing complete ports require GCC.)
+
+ To build the library and related programs, type `make'. This will
+produce a lot of output, some of which may look like errors from `make'
+(but isn't). Look for error messages from `make' containing `***'.
+Those indicate that something is really wrong.
+
+ The compilation process takes several hours even on fast hardware;
+expect at least two hours for the default configuration on i586 for
+Linux. For Hurd times are much longer. All current releases of GCC
+have a problem which causes them to take several minutes to compile
+certain files in the iconvdata directory. Do not panic if the compiler
+appears to hang.
+
+ To build and run some test programs which exercise some of the
+library facilities, type `make check'. This will produce several files
+with names like `PROGRAM.out'.
+
+ To format the `GNU C Library Reference Manual' for printing, type
+`make dvi'. You need a working TeX installation to do this.
+
+ To install the library and its header files, and the Info files of
+the manual, type `make install'. This will build things if necessary,
+before installing them. If you want to install the files in a different
+place than the one specified at configuration time you can specify a
+value for the Makefile variable `install_root' on the command line.
+This is useful to create chroot'ed environment or to prepare binary
+releases.
+
+ For now (in this alpha version, and at least on RedHat Linux), if you
+are trying to install this as your default libraries, a different
+installation method is recommended. Move `/usr/include' out of the
+way, create a new `/usr/include' directory (don't forget the symlinks
+`/usr/include/asm' and `/usr/include/linux', that should point to
+`/usr/src/linux/include/asm' and `/usr/src/linux/include/linux' -or
+wherever you keep your kernel sources-respectively), build normally and
+install into somewhere else via `install_root'. Then move your
+`/usr/include' back, and copy the newly created stuff by hand over the
+old. Remember to copy programs and shared libraries into `FILENAME.new'
+and then move `FILENAME.new' to `FILENAME', as the files might be in
+use. You will have to `ranlib' your copies of the static libraries
+`/usr/lib/libNAME.a'. You will see that `libbsd-compat.a', `libieee.a',
+and `libmcheck.a' are just object files, not archives. This is normal.
+Copy the new header files over the old ones by something like
+`cd /usr; (cd INSTALL_ROOT; tar cf - include) | tar xf -'.
+
+Recommended Tools to Install the GNU C Library
+==============================================
+
+ We recommend installing the following GNU tools before attempting to
+build the GNU C library:
+
+ * GNU `make' 3.75
+
+ You need the latest version of GNU `make'. Modifying the GNU C
+ Library to work with other `make' programs would be so hard that we
+ recommend you port GNU `make' instead. *Really.* We recommend
+ version GNU `make' version 3.75. Versions 3.76 and 3.76.1 are
+ known to have bugs which only show up in big projects like GNU
+ `libc'.
+
+ * GCC 2.8.1/EGCS 1.0.2
+
+ On most platforms, the GNU C library can only be compiled with the
+ GNU C compiler family. We recommend GCC version 2.8.1 and EGCS
+ version 1.0.2 or later versions of these two; earlier versions may
+ have problems.
+
+ * GNU `binutils' 2.8.1.0.23
+
+ Using the GNU `binutils' (assembler, linker, and related tools) is
+ preferable when possible, and they are required to build an ELF
+ shared C library. Version 2.1 of the library uses ELF symbol
+ versioning extensively. Support for this feature is incomplete or
+ buggy before binutils 2.8.1.0.23, so you must use at least this
+ version.
+
+ * GNU `texinfo' 3.11
+
+ To correctly translate and install the Texinfo documentation you
+ need this version of the `texinfo' package. Earlier versions do
+ not understand all the tags used in the document, and the
+ installation mechanisms for the info files is not present or works
+ differently.
+
+ On some Debian Linux based systems the `install-info' program
+ supplied with the system works differently from the one we expect.
+ You must therefore run `make install' like this:
+
+ make INSTALL_INFO=/path/to/GNU/install-info install
+
+ * GNU `awk' 3.0
+
+ Several files used during the build are generated using features
+ of GNU `awk' that are not found in other implementations.
+
+If you change any of the `configure.in' files you will also need
+
+ * GNU `autoconf' 2.12
+
+and if you change any of the message translation files you will need
+
+ * GNU `gettext' 0.10 or later
+
+You may also need these packages if you upgrade your source tree using
+patches, although we try to avoid this.
+
+Supported Configurations
+========================
+
+ The GNU C Library currently supports configurations that match the
+following patterns:
+
+ alpha-ANYTHING-linux
+ arm-ANYTHING-linuxaout
+ arm-ANYTHING-none
+ iX86-ANYTHING-gnu
+ iX86-ANYTHING-linux
+ m68k-ANYTHING-linux
+ powerpc-ANYTHING-linux
+ sparc-ANYTHING-linux
+ sparc64-ANYTHING-linux
+
+ Former releases of this library (version 1.09.1 and perhaps earlier
+versions) used to run on the following configurations:
+
+ alpha-dec-osf1
+ alpha-ANYTHING-linuxecoff
+ iX86-ANYTHING-bsd4.3
+ iX86-ANYTHING-isc2.2
+ iX86-ANYTHING-isc3.N
+ iX86-ANYTHING-sco3.2
+ iX86-ANYTHING-sco3.2v4
+ iX86-ANYTHING-sysv
+ iX86-ANYTHING-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 by sending electronic mail to <bug-glibc@gnu.org>.
+
+ Each case of `iX86' can be `i386', `i486', `i586', or `i686'. All
+of those configurations produce a library that can run on any of these
+processors. The library will be optimized for the specified processor,
+but will not use instructions not available on all of them.
+
+ While no other configurations are supported, there are handy aliases
+for these few. (These aliases work in other GNU software as well.)

+
+Useful hints for the installation
+=================================
+
+ There are a some more or less obvious methods one should know when
+compiling GNU libc:
+
+ * Better never compile in the source directory. Create a new
+ directory and run the `configure' from there. Everything should
+ happen automagically.
+
+ * You can use the `-j' option of GNU make by changing the line
+ specifying `PARALLELMAKE' in the Makefile generated during the
+ configuration.
+
+ It is not useful to start the `make' process using the `-j' option
+ since this option is not propagated down to the sub-`make's.
+
+ * If you made some changes after a complete build and only want to
+ check these changes run `make' while specifying the list of
+ subdirs it has to visit.
+
+ make subdirs="nss elf"
+
+ The above build run will only visit the subdirectories `nss' and
+ `elf'. Beside this it updates the `libc' files itself.
+
+Reporting Bugs
+==============
+
+ There are probably bugs in the GNU C library. There are certainly
+errors and omissions in this manual. If you report them, they will get
+fixed. If you don't, no one will ever know about them and they will
+remain unfixed for all eternity, if not longer.
+
+ To report a bug, first you must find it. Hopefully, this will be the
+hard part. Once you've found a bug, make sure it's really a bug. A
+good way to do this is to see if the GNU C library behaves the same way
+some other C library does. If so, probably you are wrong and the
+libraries are right (but not necessarily). If not, one of the libraries
+is probably wrong.
+
+ Once you're sure you've found a bug, try to narrow it down to the
+smallest test case that reproduces the problem. In the case of a C
+library, you really only need to narrow it down to one library function
+call, if possible. This should not be too difficult.
+
+ The final step when you have a simple test case is to report the bug.
+When reporting a bug, send your test case, the results you got, the
+results you expected, what you think the problem might be (if you've
+thought of anything), your system type, and the version of the GNU C
+library which you are using. Also include the files `config.status'
+and `config.make' which are created by running `configure'; they will
+be in whatever directory was current when you ran `configure'.
+
+ If you think you have found some way in which the GNU C library does
+not conform to the ISO and POSIX standards (*note Standards and
+Portability::.), that is definitely a bug. Report it!
+
+ Send bug reports to the Internet address <bug-glibc@gnu.org> using
+the `glibcbug' script which is installed by the GNU C library. If you
+have other problems with installation or use, please report those as
+well.
+
+ If you are not sure how a function should behave, and this manual
+doesn't tell you, that's a bug in the manual. Report that too! If the
+function's behavior disagrees with the manual, then either the library
+or the manual has a bug, so report the disagreement. If you find any
+errors or omissions in this manual, please report them to the Internet
+address <bug-glibc-manual@gnu.org>. If you refer to specific sections
+when reporting on the manual, please include the section names for
+easier identification.
