GNU LIBRARY GENERAL PUBLIC LICENSE

Version 2, June 1991

Copyright (C) 1991 Free Software Foundation, Inc. 51

Franklin Street, Fifth Floor, Boston, MA 02110-1301

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.
