If you use components that are licensed under GPLv3, then you are required to license the complete application the contains the GPL components under the GPL as well.

Can you use a GPL library in a no-GPL application?

No, you can’t. If the library is GPL you can’t ship it with you no-GPL application. But you can still make you application GPL, bacause you don’t need to “open source” your software. You can still sell your software as long as everyone who buys it can access the source code.

Can you use GPL binaries in commercial environment?

Another point about the title of your question “Can I use GPL software binaries in commercial environment?” : yes you can and you’re even encouraged to do so. The more free software we’ll have in commercial environments, the less hassle we’ll have to fix issues in production !

Why is Apple not allowed to distribute GPLv2?

If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all.

Do you have to give GPL source code away?

Can a library link be licensed under the GPL?

Can a GPL plugin link to a proprietary library?

Your whole plugin is covered by the GPL, since it links to a GPL library. Therefore, when you distribute your compiled binary, it must be accompanied by the source code per the requirements of the GPL. You cannot provide source code for the proprietary library, so you cannot distribute the plugin without violating the GPL.

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.

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 patent license be granted under GPLv3?

If a user decides to take the project’s code (incorporating my contributions) under GPLv3, does that mean I’ve automatically granted GPLv3’s explicit patent license to that user? If I distribute a GPLv3-covered program, can I provide a warranty that is voided if the user modifies the program?

What does GPL stand for in the GNU license?

However, if someone does that with code protected by GPLv3, section 3 says that the system will not count as an effective technological “protection” measure. This means that if you break the DRM, you’ll be free to distribute your own software that does that, and you won’t be threatened by the DMCA or similar laws.

Is it legal to use GPL code in a proprietary, closed source program?

So: as long as it’s honest-to-God communication via userspace, where the calling proprietary code forks-and-execs the called GPL wrapper program, the GPL obligations of the called program do not extend to the calling program.

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.

Do I have any obligations to open-source my code? If you use components that are licensed under GPLv3, then you are required to license the complete application the contains the GPL components under the GPL as well.

When is a GPL license incompatible with a module?

If license for a module Q has a requirement that’s incompatible with the GPL, but the requirement applies only when Q is distributed by itself, not when Q is included in a larger program, does that make the license GPL-compatible? Can I combine or link Q with a GPL-covered program?

Can you mix GPL covered software with non GPL software?

Both versions of GPL have a clause that allows “aggregations” of GPL covered software with non-GPL software. GPLv3 draft 4 puts it this way in section 5 (GPLv2 says something similar in section 2 of that license):

Do you have to license a GPL library?

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.
