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 o ering access to copy from a designated place, then o ering equivalent access to copy the source code from the same place satis es the requirement 155 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 derivative 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 le 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 signi cant 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 de ned by law. If such an object le 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 le 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 compile 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 modi cation of the work for the customer's own use and reverse engineering for debugging such modi cations. 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 modi ed executable containing the modi ed Library. It is understood that the user who changes the contents of de nitions les in the Library will not necessarily be able to recompile the application to use the modi ed de nitions. b. Accompany the work with a written o er, valid for at least three years, to give the same user the materials speci ed in Subsection 6a, above, for a charge no more than the cost 156 APPENDIX C. THE GNU LIBRARY GENERAL PUBLIC LICENSE of performing this distribution. c. If distribution of the work is made by o ering access to copy from a designated place, o er equivalent access to copy the above speci ed materials from the same place. d. 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 source code 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 nd 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 modifying 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 157 restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 11. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason not limited to patent issues , conditions are imposed on you whether by court order,
