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.

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>.
