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.) + + decstation + hp320-bsd4.3 hp300bsd + i486-gnu + i586-linux + i386-sco + i386-sco3.2v4 + i386-sequent-dynix + i386-svr4 + news + sun3-sunos4.N sun3 + sun4-solaris2.N sun4-sunos5.N + sun4-sunos4.N sun4 + +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. diff --git a/iconvdata/TESTS b/iconvdata/TESTS index e8a586c..8d72a7f 100644 --- a/iconvdata/TESTS +++ b/iconvdata/TESTS @@ -73,4 +73,4 @@ CP1254 CP1254 Y UTF8 CP1255 CP1255 Y UTF8 CP1256 CP1256 Y UTF8 CP1257 CP1257 Y UTF8 -ISO-2022-KR ISO-2022-KR Y UTF8 +ISO-2022-KR ISO-2022-KR N UTF8 diff --git a/sunrpc/svc_tcp.c b/sunrpc/svc_tcp.c index 8d728bd..41f9533 100644 --- a/sunrpc/svc_tcp.c +++ b/sunrpc/svc_tcp.c @@ -387,6 +387,7 @@ svctcp_recv (xprt, msg) cd->x_id = msg->rm_xid; return (TRUE); } + cd->strm_stat = XPRT_DIED; /* XXXX */ return (FALSE); } diff --git a/sunrpc/xdr_rec.c b/sunrpc/xdr_rec.c index db5684b..f855b3d 100644 --- a/sunrpc/xdr_rec.c +++ b/sunrpc/xdr_rec.c @@ -567,6 +567,12 @@ set_input_fragment (RECSTREAM *rstrm) return FALSE; header = ntohl (header); rstrm->last_frag = ((header & LAST_FRAG) == 0) ?
