What do I need to do if I use a LGPL licensed?

What do I need to do if I use a LGPL licensed?

57 LGPL’s basic requirement is to separate the LGPL-licensed library and your own productwell enough. That should allow users to supply their own version of the library instead of the one you’ve shipped with your software (with the bugs fixed, for instance).

Which is better LGPL 2.1 or 3.0?

LGPL 2.1 vs LGPL 3.0 Advantages and Disadvantages. From what I’ve read, LGPL 3.0 allows you to use the license together with other licenses, more permissive about that (Not even sure about that). From https://www.gnu.org/licenses/gpl-faq.html#AllCompatibility it says that it is not compatible with GPLv2, while LGPL 2.1 is compatible with it.

Is the GPL v3 compatible with the AGPL?

The final one though is that the GPL v3 series of licenses have forced compatibility with the AGPL v3, meaning that code can be taken from GPL programs and have the added restrictions of the AGPL added on in such a way that this cannot be contributed back under the same license.

Are there any shortcomings of the LGPL?

The LGPL dispenses with this uncertainty by providing a safe harbor regarding linking. The major shortcoming of this approach though is that it tends to be dependent on US legal concepts and the like, and jurisdictional definitions.

Can you sell a modified version of the GPL?

You are allowed to sell copies of the modified program commercially, but only under the terms of the GNU GPL. Thus, for instance, you must make the source code available to the users of the program as described in the GPL, and they must be allowed to redistribute and modify it as described in the GPL.

Is the GPL a license from the developer?

Strictly speaking, the GPL is a license from the developer for others to use, distribute and change the program. The developer itself is not bound by it, so no matter what the developer does, this is not a “violation” of the GPL.

Can a module be released under the GPL?

The GPL says that the whole combined program has to be released under the GPL. So your module has to be available for use under the GPL. But you can give additional permission for the use of your code. You can, if you wish, release your module under a license which is more lax than the GPL but compatible with the GPL.

Can a library be re-linked in LGPLv3?

The user is allowed to change and re-link the library used in the application or device – including reverse engineering. With LGPLv3 it is explicitly stated that the user also needs to be able to run the re-linked binary, and that sufficient installation information must be provided.

Can You redistribute software under the LGPL?

You may copy, distribute and modify the software provided that modifications are described and licensed for free under LGPL. Derivatives works (including modifications or anything statically linked to the library) can only be redistributed under LGPL, but applications that use the library don’t have to be.

Can a user change source code under LGPL?

It is recommended to either link dynamically, or provide the application source code to the user under LGPL. The user is allowed to change and re-link the library used in the application or device – including reverse engineering.

Which is the latest version of the LGPL?

The GNU Lesser General Public License version 2.1 (LGPLv2.1) in other formats: plain text, Texinfo, standalone HTML, Docbook, Markdown, ODF, RTF, and LaTeX Old versions of the LGPL This GNU Lesser General Public License counts as the successor of the GNU Library General Public License.

What are the options for compliance with the GPL?

GPL’s binary distribution sections offer a choice of compliance methods, each of which we consider in turn. Each option refers to the “Corresponding Source” code for the binary distribution, which includes the source code from which the binary was produced.

How does GPLv3 apply to offer for source?

The terms related to the offer for source are quite different if you distribute under GPLv3. Under v3, you may make source available only over a network server, as long as it is available to the general public and remains active for three years from the last distribution of your product or related spare part.

Can you use an open source library with a LGPL license?

Otherwise you have likely intertwingled the library and main application code. The LGPL license allows an application that references the binaries to remain closed-source. Also, there’s nothing preventing you from selling an open source app on the Microsoft App Marketplace.

Can a dynamically linked library be used in an independently compiled Build?

It should also be possible to exchange that dynamically linked library for an independently compiled build. Otherwise you have likely intertwingled the library and main application code.

Can You co-mingle lbgl and LGPL libraries?

You can’t co-mingle your code and LBGL libraries (static linking does co-mingle the result). As long as you don’t change the LGPL libraries you don’t have to distribute any source – at most just provide a link to the distribution of choice.

Can you use GPL and LGPL at the same time?

Some library authors therefore provide licenses that are both GPL or LGPL and also paid private licenses. Therefore, I can get the library, fully integrate it and test it (and even modify it) before deciding, yes, this works, and then pay for a license to distribute that isn’t GPL or LGPL.

Is it safe to use GPL in commercial software?

And perhaps most worrisome is that there are trolls, similar to patent trolls, who look for opportunities to sue. A troll can see that Big Corporation X has some GPL software and will without merit sue the corporation just to get a payment to go away.
