Teem: About the LGPLAbout the LGPLNOTE: Prior to the release of version 1.9, the licensing termsfor Teem changed from the LGPL, to LGPL plus exceptions whichfacilitate static linking (following 's example). Thischanges addresses legitimate concerns about the practicality of usingLGPL's code in binary-only applications. Specifically, Section 6 ofthe LGPL no longer applies to binary works linking with Teem.
Thelicensing changes also renders moot many of the technical details ofthe write-up below (especially point #4), which I originally wrote in an effortto allay common fears and misconceptions about the LGPL.It is also interesting to note, however, that while the text of theGPL and LGPL assert that linking with the library creates a derivedwork, some legal experts believe that linking creates a compilation,in the copyright sense, and not a derived work. This has implicationsfor how people who normally resist reciprocal licenses like LGPLshould understand their scope. Lawrence Rosen'scovers this issue in Chapters andMy software, is released under the ('LGPL'), for a variety of reasons. Mostimportantly, this license best implements to the notion of 'share andshare alike' which is fundamental to academic research. Also, becausethe development of this software was largely funded by the tax payingAmerican public, I feel obligated to prevent situations where mysoftware is used but can not be inspected, understood, or altered atthe level of source code.It is important to understand the difference between the LGPL and the('GPL'). Some people dismiss all GNU licenses as'viral', which is both unfortunate and false.
The most importantdifference between GPL and LGPL is that if your software uses Teem,you are in no way required to release the source for your software.However, because my software is not in the, or under a, there are certain requirements. See forclarification on the different kinds of licenses.Keep in mind, however, that the LGPL-related requirements kick inonly when you start distributing your software outside of yourschool, lab, or company.After reading through the LGPL very carefully, I wrote up thefollowing description of it, and the (minimal) responsibilities youhave if you release software which uses Teem. Others have found ithelpful because it clarifies whether or not the LGPL makes adistinction between static versus dynamic linking (the answer is no,and yes).
Also, it enumerates exactly what you'd need to do if yourelease software that uses Teem (not much). Pleaseread on.The notion of a 'derived work' is central to copyright law, becausecopyright concerns itself not just with a work, but with anythingwhich is a modified version of the original work, or a translatedversion of the work, or which is (or contains) a significant portionof the work, and so on.If you link my library with your program, the resulting binary isderived from my library (in the copyright sense) because the binarycontains translated portions of my code. The GNU licenses make nodistinction between static and dynamic linking insofar as thedefinition of a derived work, as applied to compiled software, isconcerned. Download accounting books free pdf. From the Preamble of the LGPL: 'When a program islinked with a library, whether statically or using a shared library,the combination of the two is legally speaking a combined work, aderivative of the original library.'

One reason that the LGPL is a longer and more complicated documentthan the GPL is that the LGPL makes a distinction between differentkinds of derived works, which the GPL does not make. Section 2(b) ofthe GPL applies to any derived work that you distribute orpublish, requiring that the derived work be licensed under the GPL.forexactly what that entails; it involves distribution of your program'ssource code. The LGPL also says that it applies to all derived works.But the basic thing to understand is that how the LGPL appliesin fact depends on the nature of the derived work:.
If the derived work entails a modification of Teem itself or someportion of it, then you have a 'work based on the library'. Section2(c) of the LGPL applies to that derived work as soon as youdistribute it, requiring that the work be licensed under the LGPL. If the derived work is a binary created by linking against Teem(or your modification of it), then you have a 'work which uses thelibrary'. Section 6 of the LGPL applies to this work as soon as youdistribute it, saying that the derived work can be distributed 'underthe terms of your choice, provided that.' , and goes on to describethe responsibilities of someone distributing the derived work.The important distinction here is that those responsibilities, whichI'll describe below, amount to something less than the fullLGPL.
In Italy: Modern Architectures in History, Diane Yvonne Ghirardo addresses these and other issues in her analysis of the last century of Italy’s building practices. Author by: Diane GhirardoLanguange: enPublisher by: Reaktion BooksFormat Available: PDF, ePub, MobiTotal Read: 67Total Download: 261File Size: 51,7 MbDescription: Packed in its dense, historic city centers, Italy holds some of the most prized architecture and art in the world, with which planners and politicians have had to negotiate as they struggle to cope with massive migration from the countryside to the city. Early modern architecture coincided with a sustained drive to transform a country that was still primarily rural into a modern industrial state, and throughout the twentieth century, architects in Italy have attempted to define the role of architecture within a capitalist economy and under diverse political systems.
Those responsibilities are mandated and defined by the LGPL(since the LGPL governs the distribution of any derived work), butthey are not the same as the LGPL. Most confusion about theLGPL revolves around this basic property: Section 6 of the LGPLconstrains (mildly) how you distribute compiled software using aLGPL'd library, but because those constraints are not the same as theLGPL, the LGPL does not propagate itself in the same way that the GPLdoes. This is in contrast to what is required when the derived workinvolves modification of my source, in which case the full LGPL doesapply. However, if you have found bugs or API deficiencies in mysoftware, please tell me, so that everyone can benefit. Since thissoftware is how I do research, I'll be supporting it for quite a while.So, if you distribute a program that links against Teem, withoutmodifying Teem, Section 6 of the LGPL requires you to do four things:. Give notice that your program uses Teem, and that Teem is coveredby LGPL.
All this means is that in your documentation or descriptivematerial, wherever you other list other libraries that you depend on,you also mention Teem, and that its under LGPL. You would alsomention Teem in an enumeration of the different licenses thatgovern different parts of your software, if this is the case. Supply a copy of the LGPL. This is available online inand.Its also the Teem/src/LICENSE.txt file inthe Teem distribution. If there is a section of your documentation that gives copyrightnotices for other code you use, or if copyright notices are displayedas part of the program's operation, then you need to show Teem'scopyright notice as well:Copyright (C) 2005 Gordon KindlmannCopyright (C) 2004, 2003, 2002, 2001, 2000, 1999, 1998 University of Utah.
The interesting part: You need to make it possible for users ofyour program to modify my Teem libraries, and use those modified Teemlibraries in your program. The principle of copyleft is that you passon to others the same freedoms as were available to you. The fivepossible ways to facilitate this, listed in Section 6, can besummarized as two alternatives:. If you statically link against Teem libraries,you need to accompany the distribution of your program with allsource files for the required Teem libraries, and all the object(.o) files (or source files), for your program.This way someone could re-link your various object files togetherwith modified Teem libraries to produce their own version of yourprogram. You don't have to release any source for your program ifyou don't want to.
(This much is from Section 6(a).) If you don'tsupply these materials alongside the distribution of your program,then they need to be conveyed or made available by some other means.(This is Sections 6(c)-6(e)). If you only dynamically link against shared libraries,you're done! The nature of shared libraries means that your programwill slurp up the Teem libraries (original or modified) at run-time.You don't even need to distribute Teem source. (This is Section 6(b))I mentioned above that the LGPL does not distinguish between staticand dynamic linking insofar as the definition of a derivative work isconcerned. Section 6 of LGPL says that the distinction between staticand dynamic does matter in the context of how to comply with LGPL,when you're releasing a program that uses Teem withoutmodifying it.
Can I Use Lgpl Library In Commercial Software
And this is how I imagine most everyone will use mylibraries- just linking against them as distributed.I feel that the four points of compliance, described above, are clear,fair, and very easy to deal with, especially if you take the sharedlibrary route. Also, if you've read this far, please help by clearingup misunderstandings about the LGPL when you encounter them.
.Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both.Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined witheach other. Examples. cat dog -matches anything with cat,dog or both.
cat +dog -searches for cat +dog where dog is a mandatory term. cat -dog - searches for cat excluding any result containing dog. cats —will restrict your search to results with topic named 'cats'. cats dogs —will restrict your search to results with both topics, 'cats', and 'dogs'. The UE4 EULA does not permit use of GPL licensed content in connection with the engine. Specifically:You may not combine, Distribute, or otherwise use the Licensed Technology with any code or other content which is covered by a license that would directly or indirectly require that all or part of the Licensed Technology be governed under any terms other than those of this Agreement (“Non-Compatible License”).
Code or content under the following licenses, for example, are prohibited: GNU General Public License (GPL), Lesser GPL (LGPL) (unless you are merely dynamically linking a shared library), or Creative Commons Attribution-ShareAlike License. Code or content under the following licenses, for example, are allowed: BSD License, MIT License, Microsoft Public License, or Apache License.
You may not sublicense the Licensed Technology under a Non-Compatible License. No they are not the same.
CC-Attribution only requires you to give credit where credit is due. CC-ShareAlike requires you to provide that license which entitles those you Share the content with, base code and/or original editable content. Putting content in your Unreal Engine game that is of the license CC-ShareAlike would then require you to offer all your code (technically Epic's code to the engine) free to use to whomever downloads your content under that license.While Epic gives us and virtually anyone free access to their code for the engine, they want the power to exercise their rights to decide who gets it and the ability to track who uses it.
Anyone who uses the engine must agree to the EULA - giving the code out under a CC-ShareAlike bypasses the requirements for people to agree to the EULA. I'm Epic's attorney, so I can't advise you on the interpretation of the GPL.I will note that the relevant restriction in the UE EULA is as follows:You may not combine, Distribute, orotherwise use the Licensed Technologywith any code or other content whichis covered by a license that woulddirectly or indirectly require thatall or part of the Licensed Technologybe governed under any terms other thanthose of this Agreement(“Non-Compatible License”).This means that as long as your use of GPL-licensed code doesn't violate that provision, it is OK with Epic. This becomes a fact specific question, but a possible example of such use would be a server that uses some GPL-licensed code (but does not use UE) and a client that uses no GPL-licensed code at all, but does use UE.
