Appendix A Installing the GNU C Library
***************************************
Before you do anything else, you should read the file `FAQ' located 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.
Features can be added to GNU Libc via "add-on" bundles. These are
separate tar files, which you unpack into the top level of the source
tree. Then you give `configure' the `--enable-add-ons' option to
activate them, and they will be compiled into the library. As of the
2.2 release, one important component of glibc is distributed as
"official" add-ons: the linuxthreads add-on. Unless you are doing an
unusual installation, you should get this.
Support for POSIX threads is maintained by someone else, so it's in a
separate package. It is only available for GNU/Linux systems, but this
will change in the future. Get it from the same place you got the main
bundle; the file is `glibc-linuxthreads-VERSION.tar.gz'.
You will need recent versions of several GNU tools: definitely GCC
and GNU Make, and possibly others. *Note Tools for Compilation::,
below.
A.1 Configuring and compiling GNU Libc
======================================
GNU libc can be compiled in the source directory, but we strongly advise
building it in a separate build directory. For example, if you have
unpacked the glibc sources in `/src/gnu/glibc-2.3', create a directory
`/src/gnu/glibc-build' to put the object files in. This allows
removing the whole build directory in case an error occurs, which is the
safest way to get a fresh start and should always be done.
From your object directory, run the shell script `configure' located
at the top level of the source tree. In the scenario above, you'd type
$ ../glibc-2.3/configure ARGS...
Please note that even if you're building in a separate build
directory, the compilation needs to modify a few files in the source
directory, especially some files in the manual subdirectory.
`configure' takes many options, but you can get away with knowing only
two: `--prefix' and `--enable-add-ons'. The `--prefix' option tells
`configure' where you want glibc installed. This defaults to
`/usr/local'. The `--enable-add-ons' option tells `configure' to use
all the add-on bundles it finds in the source directory. Since
important functionality is provided in add-ons, you should always
specify this option.
It may also be useful to set the CC and CFLAGS variables in the
environment when running `configure'. CC selects the C compiler that
will be used, and CFLAGS sets optimization options for the compiler.
The following list describes all of the available options for
`configure':
`--prefix=DIRECTORY'
Install machine-independent data files in subdirectories of
`DIRECTORY'. The default is to install in `/usr/local'.
`--exec-prefix=DIRECTORY'
Install the library and other machine-dependent files in
subdirectories of `DIRECTORY'. The default is to the `--prefix'
directory if that option is specified, or `/usr/local' otherwise.
`--with-headers=DIRECTORY'
Look for kernel header files in DIRECTORY, not `/usr/include'.
Glibc needs information from the kernel's private header files.
Glibc will normally look in `/usr/include' for them, but if you
specify this option, it will look in DIRECTORY instead.
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'.
`--enable-add-ons[=LIST]'
Enable add-on packages in your source tree. If this option is
specified with no list, it enables all the add-on packages it
finds. If you do not wish to use some add-on packages that you
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=linuxthreads'
`--enable-kernel=VERSION'
This option is currently only useful on GNU/Linux systems. The
VERSION parameter should have the form X.Y.Z and describes the
smallest version of the Linux kernel the generated library is
expected to support. The higher the VERSION number is, the less
compatibility code is added, and the faster the code gets.
`--with-binutils=DIRECTORY'
Use the binutils (assembler and linker) in `DIRECTORY', not the
ones the C compiler would default to. You can use this option if
the default binutils on your system cannot deal with all the
constructs in the GNU C library. In that case, `configure' will
detect the problem and suppress these constructs, so that the
library will still be usable, but functionality may be lost--for
example, you can't build a shared libc with old binutils.
`--without-fp'
Use this option if your computer lacks hardware floating-point
support and your operating system does not emulate an FPU.
these
`--disable-shared'
Don't build shared libraries even if it is possible. Not all
systems support shared libraries; you need ELF support and
(currently) the GNU linker.
`--disable-profile'
Don't build libraries with profiling information. You may want to
use this option if you don't plan to do profiling.
`--enable-omitfp'
Use maximum optimization for the normal (static and shared)
libraries, and compile separate static libraries with debugging
information and no optimization. We recommend not doing this.
The extra optimization doesn't gain you much, it may provoke
compiler bugs, and you won't be able to trace bugs through the C
library.
`--disable-versioning'
Don't compile the shared libraries with symbol version information.
Doing this will make the resulting library incompatible with old
binaries, so it's not recommended.
`--enable-static-nss'
Compile static versions of the NSS (Name Service Switch) libraries.
This is not recommended because it defeats the purpose of NSS; a
program linked statically with the NSS libraries cannot be
dynamically reconfigured to use a different name database.
`--without-tls'
By default the C library is built with support for thread-local
storage if the used tools support it. By using `--without-tls'
this can be prevented though there generally is no reason since it
creates compatibility problems.
`--build=BUILD-SYSTEM'
`--host=HOST-SYSTEM'
These options are for cross-compiling. If you specify both
options and BUILD-SYSTEM is different from HOST-SYSTEM, `configure'
will prepare to cross-compile glibc from BUILD-SYSTEM to be used
on HOST-SYSTEM. You'll probably need the `--with-headers' option
too, and you may have to override CONFIGURE's selection of the
compiler and/or binutils.
If you only specify `--host', `configure' will prepare for a
native compile but use what you specify instead of guessing what
your system is. This is most useful to change the CPU submodel.
For example, if `configure' guesses your machine as
`i586-pc-linux-gnu' but you want to compile a library for 386es,
give `--host=i386-pc-linux-gnu' or just `--host=i386-linux' and add
the appropriate compiler flags (`-mcpu=i386' will do the trick) to
CFLAGS.
If you specify just `--build', `configure' will get confused.
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 seriously wrong.
The compilation process can take several hours. Expect at least two
hours for the default configuration on i586 for GNU/Linux. For Hurd,
times are much longer. Some complex modules may take a very long time
to compile, as much as several minutes on slower machines. Do not
panic if the compiler appears to hang.
If you want to run a parallel make, simply pass the `-j' option with
an appropriate numeric parameter to `make'. You need a recent GNU
`make' version, though.
To build and run test programs which exercise some of the library
facilities, type `make check'. If it does not complete successfully,
do not use the built library, and report a bug after verifying that the
problem is not already known. *Note Reporting Bugs::, for instructions
on reporting bugs. Note that some of the tests assume they are not
being run by `root'. We recommend you compile and test glibc as an
unprivileged user.
Before reporting bugs make sure there is no problem with your system.
The tests (and later installation) use some pre-existing files of the
system such as `/etc/passwd', `/etc/nsswitch.conf' and others. These
files must all contain correct and sensible content.
To format the `GNU C Library Reference Manual' for printing, type
`make dvi'. You need a working TeX installation to do this. The
distribution already includes the on-line formatted version of the
manual, as Info files. You can regenerate those with `make info', but
it shouldn't be necessary.
The library has a number of special-purpose configuration parameters
which you can find in `Makeconfig'. These can be overwritten with the
file `configparms'. To change them, create a `configparms' in your
build directory and add values as appropriate for your system. The
file is included and parsed by `make' and has to follow the conventions
for makefiles.
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 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.
A.2 Installing the C Library
============================
To install the library and its header files, and the Info files of the
manual, type `env LANGUAGE=C LC_ALL=C make install'. This will build
things, if necessary, before installing them; however, you should still
compile everything first. If you are installing glibc as your primary
C library, we recommend that you shut the system down to single-user
mode first, and reboot afterward. This minimizes the risk of breaking
things when the library changes out from underneath.
If you're upgrading from Linux libc5 or some other C library, you
need to replace the `/usr/include' with a fresh directory before
installing it. The new `/usr/include' should contain the Linux
headers, but nothing else.
You must first build the library (`make'), optionally check it
(`make check'), switch the include directories and then install (`make
install'). The steps must be done in this order. Not moving the
directory before install will result in an unusable mixture of header
files from both libraries, but configuring, building, and checking the
library requires the ability to compile and run programs against the old
library.
If you are upgrading from a previous installation of glibc 2.0 or
2.1, `make install' will do the entire job. You do not need to remove
the old includes - if you want to do so anyway you must then follow the
order given above.
You may also need to reconfigure GCC to work with the new library.
The easiest way to do that is to figure out the compiler switches to
make it work again (`-Wl,--dynamic-linker=/lib/ld-linux.so.2' should
work on GNU/Linux systems) and use them to recompile gcc. You can also
edit the specs file (`/usr/lib/gcc-lib/TARGET/VERSION/specs'), but that
is a bit of a black art.
You can install glibc somewhere other than where you configured it
to go by setting the `install_root' variable on the command line for
`make install'. The value of this variable is prepended to all the
paths for installation. This is useful when setting up a chroot
environment or preparing a binary distribution. The directory should be
specified with an absolute file name.
Glibc 2.2 includes a daemon called `nscd', which you may or may not
want to run. `nscd' caches name service lookups; it can dramatically
improve performance with NIS+, and may help with DNS as well.
One auxiliary program, `/usr/libexec/pt_chown', is installed setuid
`root'. This program is invoked by the `grantpt' function; it sets the
permissions on a pseudoterminal so it can be used by the calling
process. This means programs like `xterm' and `screen' do not have to
be setuid to get a pty. (There may be other reasons why they need
privileges.) If you are using a 2.1 or newer Linux kernel with the
`devptsfs' or `devfs' filesystems providing pty slaves, you don't need
this program; otherwise you do. The source for `pt_chown' is in
`login/programs/pt_chown.c'.
After installation you might want to configure the timezone and
locale installation of your system. The GNU C library comes with a
locale database which gets configured with `localedef'. For example, to
set up a German locale with name `de_DE', simply issue the command
`localedef -i de_DE -f ISO-8859-1 de_DE'. To configure all locales
that are supported by glibc, you can issue from your build directory the
command `make localedata/install-locales'.
To configure the locally used timezone, set the `TZ' environment
variable. The script `tzselect' helps you to select the right value.
As an example, for Germany, `tzselect' would tell you to use
`TZ='Europe/Berlin''. For a system wide installation (the given paths
are for an installation with `--prefix=/usr'), link the timezone file
which is in `/usr/share/zoneinfo' to the file `/etc/localtime'. For
Germany, you might execute `ln -s /usr/share/zoneinfo/Europe/Berlin
/etc/localtime'.
A.3 Recommended Tools for Compilation
=====================================
We recommend installing the following GNU tools before attempting to
build the GNU C library:
* GNU `make' 3.79 or newer
You need the latest version of GNU `make'. Modifying the GNU C
Library to work with other `make' programs would be so difficult
that we recommend you port GNU `make' instead. *Really.* We
recommend GNU `make' version 3.79. All earlier versions have
severe bugs or lack features.
* GCC 3.2 or newer
The GNU C library can only be compiled with the GNU C compiler
family. As of the 2.3 release, GCC 3.2 or higher is required. As
of this writing, GCC 3.2 is the compiler we advise to use.
You can use whatever compiler you like to compile programs that
use GNU libc, but be aware that both GCC 2.7 and 2.8 have bugs in
their floating-point support that may be triggered by the math
library.
Check the FAQ for any special compiler issues on particular
platforms.
* GNU `binutils' 2.13 or later
You must use GNU `binutils' (as and ld) to build the GNU C library.
No other assembler or linker has the necessary functionality at the
moment.
* GNU `texinfo' 3.12f
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 mechanism for the info files is not present or works
differently.
* GNU `awk' 3.0, or some other POSIX awk
`Awk' is used in several places to generate files. The scripts
should work with any POSIX-compliant `awk' implementation; `gawk'
3.0 and `mawk' 1.3 are known to work.
* Perl 5
Perl is not required, but it is used if present to test the
installation. We may decide to use it elsewhere in the future.
* GNU `sed' 3.02 or newer
`Sed' is used in several places to generate files. Most scripts
work with any version of `sed'. The known exception is the script
`po2test.sed' in the `intl' subdirectory which is used to generate
`msgs.h' for the test suite. This script works correctly only
with GNU `sed' 3.02. If you like to run the test suite, you
should definitely upgrade `sed'.
If you change any of the `configure.in' files you will also need
* GNU `autoconf' 2.53 or higher
and if you change any of the message translation files you will need
* GNU `gettext' 0.10.36 or later
You may also need these packages if you upgrade your source tree using
patches, although we try to avoid this.
A.4 Supported Configurations
============================
The GNU C Library currently supports configurations that match the
following patterns:
alpha*-*-linux
arm-*-linux
cris-*-linux
hppa-*-linux
iX86-*-gnu
iX86-*-linux
ia64-*-linux
m68k-*-linux
mips*-*-linux
powerpc-*-linux
s390-*-linux
s390x-*-linux
sparc-*-linux
sparc64-*-linux
x86_64-*-linux
Former releases of this library (version 2.1 and/or 2.0) used to run
on the following configurations:
arm-*-linuxaout
arm-*-none
Very early releases (version 1.09.1 and perhaps earlier versions)
used to run on the following configurations:
alpha-dec-osf1
alpha-*-linuxecoff
iX86-*-bsd4.3
iX86-*-isc2.2
iX86-*-isc3.N
iX86-*-sco3.2
iX86-*-sco3.2v4
iX86-*-sysv
iX86-*-sysv4
iX86-force_cpu386-none
iX86-sequent-bsd
i960-nindy960-none
m68k-hp-bsd4.3
m68k-mvme135-none
m68k-mvme136-none
m68k-sony-newsos3
m68k-sony-newsos4
m68k-sun-sunos4.N
mips-dec-ultrix4.N
mips-sgi-irix4.N
sparc-sun-solaris2.N
sparc-sun-sunos4.N
Since no one has volunteered to test and fix these configurations,
they are not supported at the moment. They probably don't compile;
they definitely don't work anymore. Porting the library is not hard.
If you are interested in doing a port, please contact the glibc
maintainers. Start at `http://www.gnu.org/software/libc/' and read the
references there on how to go about getting involved and contacting the
developers.
Valid cases of `iX86' include `i386', `i486', `i586', and `i686'.
All of those configurations produce a library that can run on this
processor and newer processors. The GCC compiler by default generates
code that's optimized for the machine it's configured for and will use
the instructions available on that machine. For example if your GCC is
configured for `i686', gcc will optimize for `i686' and might issue
some `i686' specific instructions. To generate code for other models,
you have to configure for that model and give GCC the appropriate
`-march=' and `-mcpu=' compiler switches via CFLAGS.
A.5 Specific advice for GNU/Linux systems
=========================================
If you are installing GNU libc on a GNU/Linux system, you need to have
the header files from a 2.2 or newer kernel around for reference. For
some architectures, like ia64, sh and hppa, you need at least headers
from kernel 2.3.99 (sh and hppa) or 2.4.0 (ia64). You do not need to
use that kernel, just have its headers where glibc can access at them.
The easiest way to do this is to unpack it in a directory such as
`/usr/src/linux-2.2.1'. In that directory, run `make config' and
accept all the defaults. Then run `make include/linux/version.h'.
Finally, configure glibc with the option
`--with-headers=/usr/src/linux-2.2.1/include'. Use the most recent
kernel you can get your hands on.
An alternate tactic is to unpack the 2.2 kernel and run `make
config' as above; then, rename or delete `/usr/include', create a new
`/usr/include', and make symbolic links of `/usr/include/linux' and
`/usr/include/asm' into the kernel sources. You can then configure
glibc with no special options. This tactic is recommended if you are
upgrading from libc5, since you need to get rid of the old header files
anyway.
After installing GNU libc, you may need to remove or rename
`/usr/include/linux' and `/usr/include/asm', and replace them with
copies of `include/linux' and `include/asm-$ARCHITECTURE' taken from
the Linux source package which supplied kernel headers for building the
library. ARCHITECTURE will be the machine architecture for which the
library was built, such as `i386' or `alpha'. You do not need to do
this if you did not specify an alternate kernel header source using
`--with-headers'. The intent here is that these directories should be
copies of, *not* symlinks to, the kernel headers used to build the
library.
Note that `/usr/include/net' and `/usr/include/scsi' should *not* be
symlinks into the kernel sources. GNU libc provides its own versions
of these files.
GNU/Linux expects some components of the libc installation to be in
`/lib' and some in `/usr/lib'. This is handled automatically if you
configure glibc with `--prefix=/usr'. If you set some other prefix or
allow it to default to `/usr/local', then all the components are
installed there.
If you are upgrading from libc5, you need to recompile every shared
library on your system against the new library for the sake of new code,
but keep the old libraries around for old binaries to use. This is
complicated and difficult. Consult the Glibc2 HOWTO at
`http://www.imaxx.net/~thrytis/glibc' for details.
You cannot use `nscd' with 2.0 kernels, due to bugs in the
kernel-side thread support. `nscd' happens to hit these bugs
particularly hard, but you might have problems with any threaded
program.
A.6 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.
It is a good idea to verify that the problem has not already been
reported. Bugs are documented in two places: The file `BUGS' describes
a number of well known bugs and the bug tracking system has a WWW
interface at `http://sources.redhat.com/bugzilla/'. The WWW interface
gives you access to open and closed reports. A closed report normally
includes a patch or a hint on solving the problem.
To report a bug, first you must find it. With any luck, 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. It might not be the GNU library. Many
historical Unix C libraries permit things that we don't, such as
closing a file twice.
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!
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.
Do this using the WWW interface to the bug database.
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 bug
database. If you refer to specific sections of the manual, please
include the section names for easier identification.
