| | | Preamble |
| | | 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. |
| | | This license, the Lesser General Public License, applies to some |
| | | specially designated software packages--typically libraries--of the |
| | | Free Software Foundation and other authors who decide to use it. You |
| | | can use it too, but we suggest you first think carefully about whether |
| | | this license or the ordinary General Public License is the better |
| | | strategy to use in any particular case, based on the explanations below. |
| | | |
| | | 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. |
| | | When we speak of free software, we are referring to freedom of use, |
| | | 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 and use pieces of |
| | | it in new free programs; and that you are informed that 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. |
| | | 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, 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 |
| | | 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. |
| | | |
| | | Our method of protecting your rights has two steps: (1) copyright |
| | | the library, and (2) offer you this license which gives you legal |
| | | 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. |
| | | |
| | | 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. |
| | | 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, 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. |
| | | 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, 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. |
| | | 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. |
| | | |
| | | 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. |
| | | 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. |
| | | |
| | | 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. |
| | | 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. |
| | | |
| | | 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. |
| | | 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, 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. |
| | | former contains code derived from the library, whereas the latter must |
| | | be combined with the library in order to run. |
