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 other code 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. We protect your rights with
a two-step method: (1) we copyright the library, and (2) we offer you this li-
cense, which gives you legal permission to copy, distribute and/or modify the
library. To protect each distributor, we want to make it very clear that there is
no warranty for the free library. Also, if the library is modified by someone else
and passed on, the recipients should know that what they have is not the
original version, so that the original author’s reputation will not be affected by
problems that might be introduced by others.
Finally, software patents pose a constant threat to the existence of any free
program. We wish to make sure that a company cannot effectively restrict the
users of a free program by obtaining a restrictive license from a patent holder.
Therefore, we insist that any patent license obtained for a version of the
library must be consistent with the full freedom of use specified in this license.
Most GNU software, including some libraries, is covered by the ordinary GNU
General Public License. This license, the GNU Lesser General Public License,
applies to certain designated libraries, and is quite different from the ordinary
General Public License. We use this license for certain libraries in order to per-
mit linking those libraries into non-free programs. When a program is linked
with a library, whether statically or using a shared library, the combination
of the two is legally speaking a combined work, a derivative of the original
library. The ordinary General Public License therefore permits such linking
only if the entire combination fits its criteria of freedom. The Lesser General
Public License permits more lax criteria for linking other code with the library.
We call this license the “Lesser” General Public License because it does Less
to protect the user’s freedom than the ordinary General Public License. It
also provides other free software developers Less of an advantage over
competing non-free programs. These disadvantages are the reason we use
the ordinary General Public License for many libraries. However, the Lesser
license provides advantages in certain special circumstances. For example, on
rare occasions, there may be a special need to encourage the widest possible
use of a certain library, so that it becomes a de-facto standard. To achieve this,
non-free programs must be allowed to use the library. A more frequent case
is that a free library does the same job as widely used non-free libraries. In this
case, there is little to gain by limiting the free library to free software only, so
we use the Lesser General Public License. In other cases, permission to use a
particular library in non-free programs enables a greater number of people
to use a large body of free software. For example, permission to use the GNU
C Library in non-free programs enables many more people to use the whole
GNU operating system, as well as its variant, the GNU/Linux operating system.
Although the Lesser General Public License is Less protective of the users’
freedom, it does ensure that the user of a program that is linked with the
Library has the freedom and the wherewithal to run that program using a
modified version of the Library. 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, whereas the latter must be
combined with the library in order to run.
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICA
-
TION
0. This License Agreement applies to any software library or other program
which contains a notice placed by the copyright holder or other authorized
party saying it may be distributed under the terms of this Lesser 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 deriva-
tive 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 conspicu-
ously 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 deriva
-
tive 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 combine 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) Use a suitable shared library mechanism for linking with the Library. A suit-
able mechanism is one that (1) uses at run time a copy of the library already
present on the user’s computer system, rather than copying library functions
into the executable, and (2) will operate properly with a modified version of
the library, if the user installs one, as long as the modified version is interface-
compatible with the version that the work was made with.
c) 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.
d) If distribution of the work is made by offering access to copy from a
designated place, offer equivalent access to copy the above specified materi-
als from the same place.
e) 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 materials to be 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 modify-
ing 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 with this License.
11. If, as a consequence of a court judgment or allegation of patent infringe-
ment 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 simultane-
ously 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 Lesser 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 promot-
ing 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
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 an idea of what it does.> Copyright (C) year name of author This li
-
brary is free software; you can redistribute it and/or modify it under the terms
of the GNU Lesser General Public License as published by the Free Software
Foundation; either version 2.1 of the License, or (at your option) any later ver-
sion. 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 Lesser General Public
License for more details.
You should have received a copy of the GNU Lesser General Public License
along with this library; if not, write to the Free Software Foundation, Inc., 51
Franklin Street, Fifth Floor, Boston, MA 02110-1301 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:
