-How to Install the GNU C Library
-================================
-
- Installation of the GNU C library is relatively simple, but usually
-requires several GNU tools to be installed already.
-
- To configure the GNU C library for your system, run the shell script
-`configure' with `sh'. Use an argument which is the conventional GNU
-name for your system configuration--for example, `sparc-sun-sunos4.1',
-for a Sun 4 running SunOS 4.1. *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 its
-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
- static 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'.
-
- The simplest way to run `configure' is to do it in the directory
-that contains the library sources. This prepares to build the library
-in that very directory.
-
- You can prepare to build the library in some other directory by going
-to that other directory to run `configure'. In order to run configure,
-you will have to specify a directory for it, like this:
-
- mkdir sun4
- cd sun4
- ../configure sparc-sun-sunos4.1
-
-`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 `Makeconfig'; see the comments in that
-file for the details.
-
- But don't edit the file `Makeconfig' yourself--instead, create a
-file `configparms' in the directory where you are building the library,
-and define in that file the parameters you want to specify.
-`configparms' should *not* be an edited copy of `Makeconfig'; specify
-only the parameters that you want to override. To see how to set these
-parameters, find the section of `Makeconfig' that says "These are the
-configuration variables." Then for each parameter that you want to
-change, copy the definition from `Makeconfig' to your new `configparms'
-file, and change the value as appropriate for your system.
-
- 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.
-
- 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.
-
-Recommended Tools to Install the GNU C Library
-----------------------------------------------
-
- We recommend installing the following GNU tools before attempting to
-build the GNU C library:
-
- * `make' 3.76.1
-
- 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, 3.76.1 or later. Version 3.76 is
- known to have a bug which only shows up in big projects like GNU
- `libc'.
-
- * GCC 2.7.2.3
-
- On most platforms, the GNU C library can only be compiled with the
- GNU C compiler. We recommend GCC version 2.7.2 or later; earlier
- versions may have problems.
-
- On PowerPC, GCC versions dated earlier than 970904 are known not
- to work (they crash), including 2.7.2.
-
- * `binutils' 2.8.1
-
- Using the GNU `binutils' (assembler, linker, and related tools) is
- preferable when possible, and they are required to build an ELF
- shared C library. We recommend `binutils' version 2.8.1 or later;
- earlier versions are known to have problems or to not support all
- architectures.
-
- * `texinfo' 3.11
-
- To correctly translate and install the Texinfo documentation you
- need this version of the `texinfo' package. Former versions did
- not understand all the tags used in the document and also the
- installation mechanisms for the info files was not present or
- worked differently.
-
- On some Debian Linux based systems the used `install-info' program
- works differently. Here you have to run make like this:
-
- make INSTALL_INFO=/path/to/GNU/install-info install
-
- If you change any configuration file you will need also
-
- * `autoconf' 2.12
-
-and if you change any of the message translation files you will also
-need
-
- * `GNU gettext' 0.10 or later
-
-If you upgrade your source tree using the patches made available you
-probably will need those package above in any case.
-
-Supported Configurations
-------------------------
-
- The GNU C Library currently supports configurations that match the
-following patterns:
-
- alpha-ANYTHING-linux
- iX86-ANYTHING-gnu
- iX86-ANYTHING-linux
- m68k-ANYTHING-linux
- powerpc-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 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@prep.ai.mit.edu>.
-
- 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.)

-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@prep.ai.mit.edu>
-or the UUCP path <mit-eddie!prep.ai.mit.edu!bug-glibc>. 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@prep.ai.mit.edu> or the UUCP path
-<mit-eddie!prep.ai.mit.edu!bug-glibc-manual>.

Adding New Functions
====================
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'
-and `stub' directories), only in the system-dependent `Makefile' in the
-specific system's subdirectory.
+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-
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 `sunos4.1',
-the base operating system is `unix/bsd'. The algorithm used to pick
-the list of directories is simple: `configure' makes a list of the 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
-`sparc-sun-sunos4.1' results in `unix/bsd/sun/sparc/sunos4.1'.
-`configure' then tries removing each element of the list in turn, so
-`unix/bsd/sparc' and `sun/sparc' are also tried, among others. Since
+`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 `sunos4.1.1' and `sunos4.1.2' directories, `configure' tries
+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 `sparc-sun-sunos4.1' (without the `--nfp'
-option):
