Can you use an LGPL-licenced library in your commercial app?

Can you use an LGPL-licenced library in your commercial app?

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. The LGPL license allows an application that references the binaries to remain closed-source.

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).

Can you make proprietary software under the GPL?

Using a certain GNU program under the GPL does not fit our project to make proprietary software. Will you make an exception for us? It would mean more users of that program. If a programming language interpreter is released under the GPL, does that mean programs written to be interpreted by it must be under GPL-compatible licenses?

What happens if a library is released under the GPL?

If a library is released under the GPL (not the LGPL), does that mean that any program which uses it has to be under the GPL? You have a GPL’ed program that I’d like to link with my code to build a proprietary program. Does the fact that I link with your program mean I have to GPL my program?

When does your software need to be covered by the GPL?

If you release/distribute software containing GPL’d components (such as statically linked libraries), your software must be covered by the GPL. (This is the impression given for version 2; version 3 may be different.)

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.

Do you have to make GPL source available?

(b) If you do distribute YOUR APPLICATION, and you used something GPL as part of your application (even if only linking at run-time to a library) – and even if you do not charge money – and even if you do not change that GPL s/w in any way – then you MUST make the source of YOUR APPLICATION available. Making source available does not mean download.

How to comply with the LGPL in Java?

If you distribute a Java application that imports LGPL libraries, it’s easy to comply with the LGPL. Your application’s license needs to allow users to modify the library, and reverse engineer your code to debug these modifications. This doesn’t mean you need to provide source code or any details about the internals of your application.

What kind of software do you use with LGPL?

I am planning to develop a commercial software using a LGPL software. In the LGPL software that I am using some functions in a class are not fully implemented.

Is it possible to use Python with LGPL?

In summary, it looks like you can use LGPL software with Python if you either distribute the LGPL’ed library’s source code with your application (along with your modifications) or you make the end user install this library separately.

How does inheritance work under the LGPL license?

Inheritance creates derivative works in the same way as traditional linking, and the LGPL permits this type of derivative work in the same way as it permits ordinary function calls. While it is true that this particular case has not been tried in a court of law (at least that I know of), I wouldn’t stay up at night worrying about it.

Can you use GPL-ed Code in a library?

This license allows you to use GPL-ed code in a library setting without requiring your application to be GPL-ed. If the JAR file is distributed under the LGPL you should be OK. Not the answer you’re looking for?

Can you use GPL code in a JAR file?

However, most libraries are intended to be reused and the GPL license doesn’t make sense. That is why there is the LGPL or “Lesser GNU Public License”. This license allows you to use GPL-ed code in a library setting without requiring your application to be GPL-ed. If the JAR file is distributed under the LGPL you should be OK.

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.

What does GPL stand for in the GNU license?

“GPL” stands for “General Public License”. The most widespread such license is the GNU General Public License, or GNU GPL for short. This can be further shortened to “GPL”, when it is understood that the GNU GPL is the one intended.

What does the GPL say about providing source?

If you choose to provide source through a written offer, then anybody who requests the source from you is entitled to receive it. If you commercially distribute binaries not accompanied with source code, the GPL says you must provide a written offer to distribute the source code later.

Can a proprietary software be distributed under the GPL?

I use Qt in my personal projects, but they are all under the GPL so I can use the GPL licensing on Qt and not have to pay for a commercial license. Yes, you can distribute your software without making the source code public and without giving recipients the right to make changes to your software.

Is there a LGPL license for PySide2?

The thing is, PySide2 is for using the Qt framework with Python programs. Besides the LGPL license for PySide2, you’ll have to make sure that you comply with the Qt licensing terms.

Can you use Qt under the LGPL license?

You can use only those parts of Qt that are under the LGPL and have no concerns about opensource. The third alternative is to go with the GPL license, which will require your product to meet the GPL2 or GPL3 terms. There are some portions of Qt that are only available under the commercial license.

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.

Who is responsible for enforcing the GPL license?

Since the GPL is a copyright license, the copyright holders of the software are the ones who have the power to enforce the GPL. If you see a violation of the GPL, you should inform the developers of the GPL-covered software involved. They either are the copyright holders, or are connected with the copyright holders.

Which is better for commercial use MIT or LGPL?

Dual licensed means that you can choose which license applies to you. For commercial use, you will be better off choosing to follow the MIT requirements only: it is less complicated to comply with MIT than with LGPL. The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.

Is the LGPL compatible with closed source software?

LGPL: If you statically link it it in your application and you distribute the compiled application then you must release the source under the GPL to anyone who receives the binary. GPL is NOT compatible with closed source.

Which is better LGPL or MIT for jsxgraph?

JSXGraph is free software dual licensed under the GNU LGPL or MIT License. Dual licensed means that you can choose which license applies to you. For commercial use, you will be better off choosing to follow the MIT requirements only: it is less complicated to comply with MIT than with LGPL.

How are GPL libraries used in software development?

Internally, our software will be using some GPL libraries to generate its output. However, the software itself will not be distributed. Users will either receive a virtual machine with the pipeline set up which they can run locally, or submit their input data to us and access their results from a web interface.

Can a GPL program run on anyone else’s computer?

That code runs on your computer, nobody else’s. Since the GPL code doesn’t execute on anyone else’s machine, they cannot demand to see the source for the running program, even if it was modified.
