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 librar y.
We call this license the “Lesser” General Public License because it does Less to protect the user’s freedom than the 

ordinar y 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 ordinar y General Public License for many libraries. 

However, the Lesser license provides advantages in cer tain special circumstances.
For example, on rare occasions, there may be a special need to encourage the widest possible use of a cer tain librar y, 

so that it becomes a de-facto standard. To achieve this, non-free programs must be allowed to use the librar y. A more 

frequent case is that a free librar y does the same job as widely used non-free libraries. In this case, there is little to gain 

by limiting the free librar y to free software only, so we use the Lesser General Public License.
In other cases, permission to use a par ticular librar y 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 Librar y 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 Librar y has the freedom and the wherewithal to run that program using a modified 

version of the Librar y.
The precise terms and conditions for copying, distribution and modification follow. Pay close attention to the difference 

between a “work based on the librar y” and a “work that uses the librar y”. The former contains code derived from the 

librar y, whereas the latter must be combined with the librar y in order to run.

GNU LESSER GENER AL PUBLIC LICENSE

TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION

0.

  This License Agreement applies to any software librar y or other program which contains a notice placed by the 

copyright holder or other authorized par ty 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 “librar y” 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 “Librar y”, below, refers to any such software librar y or work which has been distributed under these terms. 

A “work based on the Librar y” means either the Librar y or any derivative work under copyright law: that is to 

say, a work containing the Librar y or a por tion of it, either verbatim or with modifications and/or translated 

straightfor wardly 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 librar y, 

complete source code means all the source code for all modules it contains, plus any associated inter face definition 

files, plus the scripts used to control compilation and installation of the librar y.
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 Librar y is not restricted, and output from such a program is covered 

only if its contents constitute a work based on the Librar y (independent of the use of the Librar y in a tool for 

writing it). Whether that is true depends on what the Librar y does and what the program that uses the Librar y 

does.

1.

  You may copy and distribute verbatim copies of the Librar y’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 Librar y.
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 Librar y or any por tion of it, thus forming a work based on the Librar y, 

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 librar y.
b)  You must cause the files modified to carr y 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 par ties under the terms of this 

License.
