informed that you can do these things.
To protect your rights, we need to make re-
strictions that forbid distributors to deny you
these rights or to ask you to surrender these
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, re-
ceive 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 recompil-
ing 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 license, 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 permit 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 ad-
vantage 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 particu-
lar 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 copy-
ing, 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.
