Can you use a GPL without a proprietary library?

Can you use a GPL without a proprietary library?

So although you can “use” your combination of GPL program and proprietary license, you cannot “convey” or “distribute” the GPL program without the proprietary library, unless that proprietary library is a “system library”.

Why is GPL covered software better than proprietary software?

This is for two reasons: to make sure that users who get the software get the freedom they should have, and to encourage people to give back improvements that they make. However, in many cases you can distribute the GPL-covered software alongside your proprietary system.

Is the GPL code in a derivative work public?

Now, the entirety of the original work has been copied into a work that is GPL licenced and thus the source code is public, so the original work’s code is now public, true. But it is public because it was included in a derivative work. It’s a subtle but important difference.

Can a company make a modified version of the GPL?

(#UnreleasedMods) The GPL permits anyone to make a modified version and use it without ever distributing it to others. What this company is doing is a special case of that. Therefore, the company does not have to release the modified sources.

Can a distributed GPL program violate its own license?

Infecting means derived program violate GPL, infected means GPL program violate its own license. No problem exists when you compile a distributed GPL source as act individual (person, org, company).

Can a GPL code be used in a commercial?

ANSWER: You can if you want to. If your application is not distributed with the GPL code and you make users download it separately to make use of it, then your case is a little bit more special and might provoke some argument, but the same principle will most likely ultimately apply: you must make your source available.

Can a GPL tool be made open source?

Unless someone in the comments disagrees, I’d like to point out that if you need to use a bit of GPL code at your devops / build layer, you can make that tool a separate application which CAN, potentially, be made open source w/o giving away the product your other-named tool builds. If you use GPL code at runtime, you gotta give out the source.

Why does GPL have to cover the whole thing?

So the GPL has to cover the whole thing. If the two programs remain well separated, like the compiler and the kernel, or like an editor and a shell, then you can treat them as two separate programs—but you have to do it properly. The issue is simply one of form: how you describe what you are doing. Why do we care about this?

Which is the best example of GPLv3 free software?

The Apache License 2.0 is a prime example. Lots of great free software is available under this license, with strong communities surrounding it. We hope that this change in GPLv3 will foster more cooperation and sharing within the free software community.

How does GPLv3 stop people from using cryptography?

GPLv3 does not stop people from using cryptography; we wouldn’t want it to. It only stops people from taking away the rights that the license provides you—whether through patent law, technology, or any other means.

Do you have to provide source for C library?

They also draw the line at System Libraries: you’re not required to provide the source for certain core components of the operating system, such as the C library.

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 a GPL library be used by MIT?

Anyone who liked your contributions and wished to use them under MIT-only could come to you for them.

Which is an example of a GPL license?

As a practical example of a project with such a policy consider FFmpeg. It’s overall license is the LGPL (and not the MIT, but from the point of view of the GPL the results are the same).

Can you make proprietary libraries available in source code form?

Such Covered Software must also be made available in Source Code Form, as described in Section 3.1, and You must inform recipients of the Executable Form how they can obtain a copy of such Source Code Form by reasonable means in a timely manner, at a charge no more than the cost of distribution to the recipient; and

Can you use proprietary libraries in MPL 2.0 Licensed source?

My practical feeling is that this is fine otherwise there could be no use of this license on many platforms whose base libraries are proprietary, like on iOS for example. The only difference being that these libraries are distributed to registered developers. It should be sufficient to just read the MPL. 3.2.

Which is the best license for a library?

See “How to choose a license for your own work” for general recommendations about choosing a license for your work. The GNU Project has two principal licenses to use for libraries. One is the GNU Lesser GPL; the other is the ordinary GNU GPL.

Can a GPL program be used as a drop in replacement?

If you are using a GPL program, but you could easily use a different one as a drop-in replacement, you’re communicating at arms length. If using a different, but similar program, means you have to re-architect your application, it’s not at arms length.

Can a GPL plugin be distributed as a compiled executable?

Yes, the GPL does not affect private use. This is both due to private use exception in copyright law, and because the GPL explicitly says that it only applies to distributions of “something” containing GPL code. Can I distribute the plugin as a compiled executable?

Can a software be released in the public domain?

Public domain software can be used by anyone for any purpose, and cannot be released under a copyright license (including typical open source software licenses). However, software written entirely by federal government employees as part of their official duties can be released as “public domain

Do you need a license to use open source software?

Software licenses, including those for open source software, are typically based on copyright law. Under U.S. copyright law, users must have permission (i.e. a license) from the copyright holder(s) before they can obtain a copy of software to run on their system(s).

Can a MIT library be shared under the GPL?

This means that the MIT portions can be shared under that license, but if the whole project is distributed, it must be under GPL. No. GPL is copyleft, meaning you have to distrubute any derivative works of the original also under the GPL.

Can a GPL license invalidate a license?

This License gives no permission to license the work in any other way, but it does not invalidate such permission if you have separately received it. So if GPL-licensed code ever gets included in your project, for example via linking against a GPL’d library, you must also provide your whole project under the GPL.
