GNU GPL or Lesser questions by dsp on Nov 16, 2005			dsp Posts: 8 Joined: Jan 23, 2011 Last seen: Nov 2, 2026
I've read over both GPL and GNU Lesser licenses, and have one concern. Hopefully someone here has experience or can offer an explanation. My concern is this: I've written/am writing core modules for my TI Dev board project, and want to release these cores as 'free software' to individuals, however, would like those that would use this set of cores in a profitable way to contribute back to QorTek in one form or another. I have no problem with students/individuals using these cores for school/personal projects, in fact I encourage them to do so. But if XYZ Corp wants to use the cores in verbatim/modified form and sell that software based on these cores, is there a way to impose fees on them? Is there another license that covers this? I dont want to start any flame wars, I'm just new to GNU GPL/Lesser and general software licenses. Thanks in advance. Brian I've read over both GPL and GNU Lesser licenses, and have one concern.

If you maid a difference between student and XYZ Corp in your licence, you don't do 'free software' anymore. You could use GPL or LGPL to force user to publish there modification to your core. If you own all the copyright, you could also sell "closed" version of your code, like Trolltech do for Qt and MySQL Labs with Mysql.

Someone please correct me if I'm wrong, but I think the general difference is: If your cores were LGPL, anyone could use it in whatever design they wanted, but if they changed any of the cores you released in the process, they would have to release their changes. If your cores were GPL, and someone used them in a design, their entire design would have be released under the GPL. At least, that's my understanding (or misunderstanding).

Well, I've done a little more reading, this time on other's licensing. I could very well add the stipulation that if XYZ Corp wanted to redistribute a proprietary closed product based on our work, then they would need to license the software from QorTek in a different manner not by GPL/LGPL. The non-GPL/LGPL should not contain 3rd party contributed source without permission or some other agreement in place. Nicolas as you noted with MySQL Example, MySQL allows anyone to use/redistribute/sell MySQL so long as the source is made available. However, they have a secondary model that allows for redistribution of closed software by purchase of a separate license. This discourages closed software but does not make it impossible. My reasoning for a closed licensing agreement: Again, I donÂ’t want to start a flame war, but, sometimes there IS A NEED for closed software, case in point, military based applications. Since QorTek deals with military type contracts, we are obligated to keep certain things proprietary, and if they wish to include OUR LGPL work as part of a system, IÂ’m sure they would not want to divulge how the entire systems works. There will be no response from me to anyone that has to do with the previous paragraph relating to beliefs on open vs. closed software (PERIOD) Pending CEO approval, QorTek will be releasing the IP under LGPL. Nicolas, Thank you for your help in clearing this up. ----- Original Message ----- From: Nicolas Boulay<<A HREF="http://www.opencores.org/mailman/listinfo/cores">nico at s...</A>> To: Date: Wed Nov 16 20:08:04 CET 2005 Subject: [oc] GNU GPL or Lesser questions [q] If you maid a difference between student and XYZ Corp in your licence, you don't do 'free software' anymore.

You are completly right. At first sigh, because it's what happen in the software world. GPL force "derivative form of work" to be release under GPL. That means that if you build a programm that is based under mysql, it must be GPL. BUT if you use something "beside" it, it's ok. It's what's happen with closed source Nvidia code inside the Linux kernel. The driver was first maid for windows not targeting only linux, as for the code of one old fiel system. That's a very specific case. A more annoying things, is that you mix copyright/source/GPL with real things that are not inside the copyright law. So i don't realy know the obligation towards the source code when you have the object in your hand. In the SW world, if you have a GPL binarie, your provider must provide you the source code as said by the GPL. But GPL is a licence on copyrighted material which not apply to goods. So i don't know what could happen.

Right, if someone wanted to build this core into say an MP3Player and sell a million of them, there is nothing to stop them from that. I guess GPL/LGPL rely on karma in hopes that some of the profit from sales goes back to the owner/inventor to help further those organizations developments. And you right, there is no good way to say, students/individuals can use software for free, but people who profit from it must pay for it. So my conclusion on that is to just make it 'free software' and hope for the best. At the very least, we all can benefit from advances in free software.

Regards, Brian ----- Original Message ----- From: Mike Delaneymmdst23 at g...> To: Date: Thu Nov 17 05:36:16 CET 2005 Subject: [oc] GNU GPL or Lesser questions Someone please correct me if I'm wrong, but I think the general difference is: If your cores were LGPL, anyone could use it in whatever design they wanted, but if they changed any of the cores you released in the process, they would have to release their changes. If your cores were GPL, and someone used them in a design, their entire design would have be released under the GPL. At least, that's my understanding (or misunderstanding).
