[ **] Closing shared objects in statically linked binaries most of the
times leads to crashes during the dlopen(). Hard to fix.
[ **] There are problems with signal handling when using LinuxThreads.
[ **] The RPC code is not 64 bit clean. This is getting slowly fixed
but expect incompatible changes on 64 bit platforms like Alpha.
[ **] If a DSO is using implicitly libpthread and the application itself
does not there is a name lookup problem. E.g., the function fork()
will be found in the libc.so instead of libpthread since the thread
library is behind the libc. To correct this problem it must *not*
be relied on the currently still enabled handling of weak symbols
in the dynamic linker. Instead explicit tests for the availability
of the libpthread version are needed. [PR libc/2325]
[ *] The precision of the `sinhl' and/or `asinhl' function do not seem
to be the best.

separate tar files, which you unpack into the top level of the source

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.

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.
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-2.4/configure ARGS...
Please note that even if you're building in a separate build
Please note that even though 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.
`configure' takes many options, but the only one that is usually
mandatory is `--prefix'. This option tells `configure' where you want
glibc installed. This defaults to `/usr/local', but the normal setting
to install as the standard system library is `--prefix=/usr' for
GNU/Linux systems and `--prefix=' (an empty prefix) for GNU/Hurd
systems.
It may also be useful to set the CC and CFLAGS variables in the

You may specify an explicit list of add-ons to use in LIST,
separated by spaces or commas (if you use spaces, remember to
quote them from the shell). Each add-on in LIST can be an
absolute directory name or can be a directory name relative to the
main source directory, or relative to the build directory (that
is, the current working directory). For example,

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.

using `glibc' in the "product" field.
Version 2.5
* For Linux, the sorting of addresses returned by getaddrinfo now also
handles rules 3, 4, and 7 from RFC 3484. I.e., all rules are handled.
Implemented by Ulrich Drepper.
* Allow system admin to configure getaddrinfo with the /etc/gai.conf file.
Implemented by Ulrich Drepper.
* New Linux interfaces: splice, tee, sync_file_range, vmsplice.
* New iconv module for MIK. Contributed by Alexander Shopov.
* For sites with broken group and/or passwd database, the auto-propagate
option of nscd can prevent creating ID lookup entries from the results
of a name lookup and vice versa. This usually is no problem but some
site might have problems with the default behavior.
Implemented by Ulrich Drepper.
* Iterating over entire database in NIS can be slow. With the
SETENT_BATCH_READ option in /etc/default/nss a system admin can decide
to trade time for memory. The entire database will be read at once.
Implemented by Ulrich Drepper.
* The interfaces introduced in RFC 3542 have been implemented by
Ulrich Drepper.
* Support for the new ELF hash table format was added by Ulrich Drepper.
* Support for priority inheritance mutexes added by Jakub Jelinek and
Ulrich Drepper.
* Support for priority protected mutexes added by Jakub Jelinek.
* New locales: nr_ZA, pa_PK, ca_AD, ca_FR, ca_IT, el_CY, tr_CY, as_IN,
or_IN, csb_PL, fy_NL, sr_ME.
Version 2.4
* More overflow detection functions.
* New iconv converters for IBM1025, IBM1122, IBM1137, IBM1153,
IBM1154, IBM1155, IBM1156, IBM1157, and IBM1158 contributed by Jiro Sekiba.
More converters for IBM803, IBM901, IBM902, IBM921, IBM1008, IBM1097,
IBM1112, IBM1123, IBM1130, IBM1140, IBM1141, IBM1142, IBM1143, IBM1144,
IBM1145, IBM1146, IBM1147, IBM1148, IBM1149, IBM1166, IBM1167, IBM4517,
IBM4899, IBM4909, IBM4971, IBM5347, IBM9030, IBM9066, IBM9448, IBM12712,
IBM16804, IBM1364, IBM1371, IBM1388, IBM1390, and IBM1399 contributed
by Masahide Washizawa.
* It is now possible to install audit libraries for the dynamic linker using
LD_AUDIT. Implemented by Ulrich Drepper.
* The LinuxThreads add-on, providing pthreads on Linux 2.4 kernels, is no
longer supported. The new NPTL implementation requires Linux 2.6 kernels.
For a libc and libpthread that works well on Linux 2.4 kernels, we
recommend using the stable 2.3 branch.
* The new function open_wmemstream acts like open_memstream,
but uses a wchar_t wide character buffer.
* The new function ppoll is an improved version of poll, similar to pselect.
* New interfaces: fdopendir, openat, fstatat, fchmodat, fchownat,
futimesat, faccessat, mkdirat, mkfifoat, mknodat,
renameat, unlinkat, linkat, symlinkat, readlinkat.
* New Linux kernel system calls: unshare,
inotify_init, inotify_add_watch, inotify_rm_watch.
* The euidaccess function is now also known by the alias eaccess,
for compatibility with some other systems.
* Timezone data updated to 2006b version.
Version 2.3.6
* The following bugs are resolved with this release:

In GNU/Linux systems, the C library works with the Linux kernel to
implement the operating system behavior seen by user applications.
In GNU/Hurd systems, it works with a microkernel and Hurd servers.
Past releases of this library ran on a variety of configurations that are
no longer supported. Porting the library is not hard. If you are
interested in doing a port, please contact the glibc maintainers;
see http://www.gnu.org/software/libc/ for more information.
The GNU C Library implements much of the POSIX.1 functionality in the
GNU/Hurd system, using configurations i[34567]86-*-gnu.
There are some add-ons which can be used together with GNU libc. They
are designed in a way to ease the installation by integrating them in
the libc source tree. Simply get the add-ons you need and use the
--enable-add-ons option of the `configure' script to tell where the
add-ons are found. Please read the FAQ file for more details.
When working with Linux kernels, the GNU C Library version 2.4 is
intended primarily for use with Linux kernel version 2.6.0 and later.
We only support using the NPTL implementation of pthreads, which is now
the default configuration. Most of the C library will continue to work
on older Linux kernels and many programs will not require a 2.6 kernel
to run correctly. However, pthreads and related functionality will not
work at all on old kernels and we do not recommend using glibc 2.4 with
any Linux kernel prior to 2.6.
See the file INSTALL to find out how to configure, build, install, and port
the GNU C library. You might also consider reading the WWW pages for the
GNU libc at http://www.gnu.org/software/libc/libc.html.
All Linux kernel versions prior to 2.6.16 are known to have some bugs that
may cause some of the tests related to pthreads in "make check" to fail.
If you see such problems, please try the test suite on the most recent
Linux kernel version that you can use, before pursuing those bugs further.
The GNU C Library is completely documented by the Texinfo manual found
in the `manual/' subdirectory. The manual is still being updated and
contains some known errors and omissions; we regret that we do not
have the resources to work on the manual as much as we would like.
Please send comments on the manual to <bug-glibc-manual@gnu.org>, and
not to the library bug-reporting address.
The old LinuxThreads add-on implementation of pthreads for older Linux
kernels is no longer supported, and we are not distributing it with this
release. Someone has volunteered to revive its maintenance unofficially
for at least a short time for the benefit of those using Linux kernels
older than 2.6, but a working version is not presently available. When
it is in working condition, we will make it available alongside future
glibc releases. LinuxThreads will not be supported.
The GNU C Library supports these configurations for using Linux kernels:

sh[34]-*-linux-gnu Requires Linux 2.6.11
The code for other CPU configurations supported by volunteers outside of
the core glibc maintenance effort is contained in the separate `ports'
add-on. You can find glibc-ports-2.5 distributed separately in the
same place where you got the main glibc distribution files.
Currently these configurations are known to work using the `ports' add-on:
arm-*-linux-gnu Requires Linux 2.6.15 for NPTL, no SMP support
arm-*-linux-gnueabi Requires Linux 2.6.16-rc1 for NPTL, no SMP
mips-*-linux-gnu Requires Linux 2.6.12 for NPTL
mips64-*-linux-gnu Requires Linux 2.6.12 for NPTL
The ports distribution also contains code for other configurations that
do not work or have not been maintained recently, but will be of use to
anyone trying to make a new configuration work. If you are interested
in doing a port, please contact the glibc maintainers; see
http://www.gnu.org/software/libc/ for more information.
See the file INSTALL to find out how to configure, build, and install
the GNU C Library. You might also consider reading the WWW pages for

Currently these configurations are known to work using the `ports' add-on:
arm-*-linux-gnu Requires Linux 2.6.15 for NPTL, no SMP support
arm-*-linux-gnueabi Requires Linux 2.6.16-rc1 for NPTL, no SMP
mips-*-linux-gnu Requires Linux 2.6.12 for NPTL
mips64-*-linux-gnu Requires Linux 2.6.12 for NPTL
The ports distribution also contains code for other configurations that
do not work or have not been maintained recently, but will be of use to
anyone trying to make a new configuration work. If you are interested
in doing a port, please contact the glibc maintainers; see
http://www.gnu.org/software/libc/ for more information.
See the file INSTALL to find out how to configure, build, and install
the GNU C Library. You might also consider reading the WWW pages for
the C library at http://www.gnu.org/software/libc/.
The GNU C Library is (almost) completely documented by the Texinfo manual
found in the `manual/' subdirectory. The manual is still being updated
and contains some known errors and omissions; we regret that we do not
have the resources to work on the manual as much as we would like. For
corrections to the manual, please file a bug in the `manual' component,
following the bug-reporting instructions below. Please be sure to check
the manual in the current development sources to see if your problem has
already been corrected.
The file NOTES contains a description of the feature-test macros used
in the GNU C library, explaining how you can tell the library what

GNU LIBRARY GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1991 Free Software Foundation, Inc.
59 Temple Place - Suite 330, Boston, MA 02111-1307, USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
[This is the first released version of the library GPL. It is
numbered 2 because it goes with version 2 of the ordinary GPL.]
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
Licenses are intended to guarantee your freedom to share and change
free software--to make sure the software is free for all its users.
This license, the Library General Public License, applies to some
specially designated Free Software Foundation software, and to any
other libraries whose authors decide to use it. You can use it for
your libraries, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if
you distribute copies of the library, or if you modify it.
For example, if you distribute copies of the library, whether gratis
or for a fee, you must give the recipients all the rights that we gave
you. You must make sure that they, too, receive or can get the source
code. If you link a program with the library, you must provide
complete object files to the recipients so that they can relink them
with the library, after making changes to the library and recompiling
it. And you must show them these terms so they know their rights.
Our method of protecting your rights has two steps: (1) copyright
the library, and (2) offer you this license which gives you legal
permission to copy, distribute and/or modify the library.
Also, for each distributor's protection, we want to make certain
that everyone understands that there is no warranty for this free
library. If the library is modified by someone else and passed on, we
want its recipients to know that what they have is not the original
version, so that any problems introduced by others will not reflect on
the original authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that companies distributing free
software will individually obtain patent licenses, thus in effect
transforming the program into proprietary software. To prevent this,
we have made it clear that any patent must be licensed for everyone's
free use or not licensed at all.
Most GNU software, including some libraries, is covered by the ordinary
GNU General Public License, which was designed for utility programs. This
license, the GNU Library General Public License, applies to certain
designated libraries. This license is quite different from the ordinary
one; be sure to read it in full, and don't assume that anything in it is
the same as in the ordinary license.
The reason we have a separate public license for some libraries is that
they blur the distinction we usually make between modifying or adding to a
program and simply using it. Linking a program with a library, without
changing the library, is in some sense simply using the library, and is
analogous to running a utility program or application program. However, in
a textual and legal sense, the linked executable is a combined work, a
derivative of the original library, and the ordinary General Public License
treats it as such.
Because of this blurred distinction, using the ordinary General
Public License for libraries did not effectively promote software
sharing, because most developers did not use the libraries. We
concluded that weaker conditions might promote sharing better.
However, unrestricted linking of non-free programs would deprive the
users of those programs of all benefit from the free status of the
libraries themselves. This Library General Public License is intended to
permit developers of non-free programs to use free libraries, while
preserving your freedom as a user of such programs to change the free
libraries that are incorporated in them. (We have not seen how to achieve
this as regards changes in header files, but we have achieved it as regards
changes in the actual functions of the Library.) The hope is that this
will lead to faster development of free libraries.
The precise terms and conditions for copying, distribution and
modification follow. Pay close attention to the difference between a
"work based on the library" and a "work that uses the library". The
former contains code derived from the library, while the latter only
works together with the library.
Note that it is possible for a library to be covered by the ordinary
General Public License rather than by this special one.
GNU LIBRARY GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License Agreement applies to any software library which
contains a notice placed by the copyright holder or other authorized
party saying it may be distributed under the terms of this Library
General Public License (also called "this License"). Each licensee is
addressed as "you".
A "library" means a collection of software functions and/or data
prepared so as to be conveniently linked with application programs
(which use some of those functions and data) to form executables.
The "Library", below, refers to any such software library or work
which has been distributed under these terms. A "work based on the
Library" means either the Library or any derivative work under
copyright law: that is to say, a work containing the Library or a
portion of it, either verbatim or with modifications and/or translated
straightforwardly into another language. (Hereinafter, translation is
included without limitation in the term "modification".)
"Source code" for a work means the preferred form of the work for
making modifications to it. For a library, complete source code means
all the source code for all modules it contains, plus any associated
interface definition files, plus the scripts used to control compilation
and installation of the library.
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running a program using the Library is not restricted, and output from
such a program is covered only if its contents constitute a work based
on the Library (independent of the use of the Library in a tool for
writing it). Whether that is true depends on what the Library does
and what the program that uses the Library does.
1. You may copy and distribute verbatim copies of the Library's
complete source code as you receive it, in any medium, provided that
you conspicuously and appropriately publish on each copy an
appropriate copyright notice and disclaimer of warranty; keep intact
all the notices that refer to this License and to the absence of any
warranty; and distribute a copy of this License along with the
Library.
You may charge a fee for the physical act of transferring a copy,
and you may at your option offer warranty protection in exchange for a
fee.
2. You may modify your copy or copies of the Library or any portion
of it, thus forming a work based on the Library, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) The modified work must itself be a software library.
b) You must cause the files modified to carry prominent notices
stating that you changed the files and the date of any change.
c) You must cause the whole of the work to be licensed at no
charge to all third parties under the terms of this License.
d) If a facility in the modified Library refers to a function or a
table of data to be supplied by an application program that uses
the facility, other than as an argument passed when the facility
is invoked, then you must make a good faith effort to ensure that,
in the event an application does not supply such function or
table, the facility still operates, and performs whatever part of
its purpose remains meaningful.
(For example, a function in a library to compute square roots has
a purpose that is entirely well-defined independent of the
application. Therefore, Subsection 2d requires that any
application-supplied function or table used by this function must
be optional: if the application does not supply it, the square
root function must still compute square roots.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Library,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Library, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote
it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Library.
In addition, mere aggregation of another work not based on the Library
with the Library (or with a work based on the Library) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may opt to apply the terms of the ordinary GNU General Public
License instead of this License to a given copy of the Library. To do
this, you must alter all the notices that refer to this License, so
that they refer to the ordinary GNU General Public License, version 2,
instead of to this License. (If a newer version than version 2 of the
ordinary GNU General Public License has appeared, then you can specify
that version instead if you wish.) Do not make any other change in
these notices.
Once this change is made in a given copy, it is irreversible for
that copy, so the ordinary GNU General Public License applies to all
subsequent copies and derivative works made from that copy.
This option is useful when you wish to copy part of the code of
the Library into a program that is not a library.
4. You may copy and distribute the Library (or a portion or
derivative of it, under Section 2) in object code or executable form
under the terms of Sections 1 and 2 above provided that you accompany
it with the complete corresponding machine-readable source code, which
must be distributed under the terms of Sections 1 and 2 above on a
medium customarily used for software interchange.
If distribution of object code is made by offering access to copy
from a designated place, then offering equivalent access to copy the
source code from the same place satisfies the requirement to
distribute the source code, even though third parties are not
compelled to copy the source along with the object code.
5. A program that contains no derivative of any portion of the
Library, but is designed to work with the Library by being compiled or
linked with it, is called a "work that uses the Library". Such a
work, in isolation, is not a derivative work of the Library, and
therefore falls outside the scope of this License.
However, linking a "work that uses the Library" with the Library
creates an executable that is a derivative of the Library (because it
contains portions of the Library), rather than a "work that uses the
library". The executable is therefore covered by this License.
Section 6 states terms for distribution of such executables.
When a "work that uses the Library" uses material from a header file
that is part of the Library, the object code for the work may be a
derivative work of the Library even though the source code is not.
Whether this is true is especially significant if the work can be
linked without the Library, or if the work is itself a library. The
threshold for this to be true is not precisely defined by law.
If such an object file uses only numerical parameters, data
structure layouts and accessors, and small macros and small inline
functions (ten lines or less in length), then the use of the object
file is unrestricted, regardless of whether it is legally a derivative
work. (Executables containing this object code plus portions of the
Library will still fall under Section 6.)
Otherwise, if the work is a derivative of the Library, you may
distribute the object code for the work under the terms of Section 6.
Any executables containing that work also fall under Section 6,
whether or not they are linked directly with the Library itself.
6. As an exception to the Sections above, you may also compile or
link a "work that uses the Library" with the Library to produce a
work containing portions of the Library, and distribute that work
under terms of your choice, provided that the terms permit
modification of the work for the customer's own use and reverse
engineering for debugging such modifications.
You must give prominent notice with each copy of the work that the
Library is used in it and that the Library and its use are covered by
this License. You must supply a copy of this License. If the work
during execution displays copyright notices, you must include the
copyright notice for the Library among them, as well as a reference
directing the user to the copy of this License. Also, you must do one
of these things:
a) Accompany the work with the complete corresponding
machine-readable source code for the Library including whatever
changes were used in the work (which must be distributed under
Sections 1 and 2 above); and, if the work is an executable linked
with the Library, with the complete machine-readable "work that
uses the Library", as object code and/or source code, so that the
user can modify the Library and then relink to produce a modified
executable containing the modified Library. (It is understood
that the user who changes the contents of definitions files in the
Library will not necessarily be able to recompile the application
to use the modified definitions.)
b) Accompany the work with a written offer, valid for at
least three years, to give the same user the materials
specified in Subsection 6a, above, for a charge no more
than the cost of performing this distribution.
c) If distribution of the work is made by offering access to copy
from a designated place, offer equivalent access to copy the above
specified materials from the same place.
d) Verify that the user has already received a copy of these
materials or that you have already sent this user a copy.
For an executable, the required form of the "work that uses the
Library" must include any data and utility programs needed for
reproducing the executable from it. However, as a special exception,
the source code distributed need not include anything that is normally
distributed (in either source or binary form) with the major
components (compiler, kernel, and so on) of the operating system on
which the executable runs, unless that component itself accompanies
the executable.
It may happen that this requirement contradicts the license
restrictions of other proprietary libraries that do not normally
accompany the operating system. Such a contradiction means you cannot
use both them and the Library together in an executable that you
distribute.
7. You may place library facilities that are a work based on the
Library side-by-side in a single library together with other library
facilities not covered by this License, and distribute such a combined
library, provided that the separate distribution of the work based on
the Library and of the other library facilities is otherwise
permitted, and provided that you do these two things:
a) Accompany the combined library with a copy of the same work
based on the Library, uncombined with any other library
facilities. This must be distributed under the terms of the
Sections above.
b) Give prominent notice with the combined library of the fact
that part of it is a work based on the Library, and explaining
where to find the accompanying uncombined form of the same work.
8. You may not copy, modify, sublicense, link with, or distribute
the Library except as expressly provided under this License. Any
attempt otherwise to copy, modify, sublicense, link with, or
distribute the Library is void, and will automatically terminate your
rights under this License. However, parties who have received copies,
or rights, from you under this License will not have their licenses
terminated so long as such parties remain in full compliance.
9. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Library or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Library (or any work based on the
Library), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Library or works based on it.
10. Each time you redistribute the Library (or any work based on the
Library), the recipient automatically receives a license from the
original licensor to copy, distribute, link with or modify the Library
subject to these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
11. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Library at all. For example, if a patent
license would not permit royalty-free redistribution of the Library by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Library.
If any portion of this section is held invalid or unenforceable under any
particular circumstance, the balance of the section is intended to apply,
and the section as a whole is intended to apply in other circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
12. If the distribution and/or use of the Library is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Library under this License may add
an explicit geographical distribution limitation excluding those countries,
so that distribution is permitted only in or among countries not thus
excluded. In such case, this License incorporates the limitation as if
written in the body of this License.
13. The Free Software Foundation may publish revised and/or new
versions of the Library General Public License from time to time.
Such new versions will be similar in spirit to the present version,
but may differ in detail to address new problems or concerns.
Each version is given a distinguishing version number. If the Library
specifies a version number of this License which applies to it and
"any later version", you have the option of following the terms and
conditions either of that version or of any later version published by
the Free Software Foundation. If the Library does not specify a
license version number, you may choose any version ever published by
the Free Software Foundation.
14. If you wish to incorporate parts of the Library into other free
programs whose distribution conditions are incompatible with these,
write to the author to ask for permission. For software which is
copyrighted by the Free Software Foundation, write to the Free
Software Foundation; we sometimes make exceptions for this. Our
decision will be guided by the two goals of preserving the free status
of all derivatives of our free software and of promoting the sharing
and reuse of software generally.
NO WARRANTY
15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
DAMAGES.
END OF TERMS AND CONDITIONS
Appendix: How to Apply These Terms to Your New Libraries
If you develop a new library, and you want it to be of the greatest
possible use to the public, we recommend making it free software that
everyone can redistribute and change. You can do so by permitting
redistribution under these terms (or, alternatively, under the terms of the
ordinary General Public License).
To apply these terms, attach the following notices to the library. It is
safest to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least the
"copyright" line and a pointer to where the full notice is found.
<one line to give the library's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This library is free software; you can redistribute it and/or
modify it under the terms of the GNU Library General Public
License as published by the Free Software Foundation; either
version 2 of the License, or (at your option) any later version.
This library is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU
Library General Public License for more details.
You should have received a copy of the GNU Library General Public
License along with this library; if not, write to the Free
Software Foundation, Inc., 59 Temple Place - Suite 330, Boston,
MA 02111-1307, USA
Also add information on how to contact you by electronic and paper mail.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the library, if
necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the
library `Frob' (a library for tweaking knobs) written by James Random Hacker.
<signature of Ty Coon>, 1 April 1990
Ty Coon, President of Vice
That's all there is to it!
