That is great, but the commercial licensers have no obligation to distribute any code. The library is LGPL3, at best, and therefore while able to be used in commercial software, cannot be used by commercial licensers. If it were BSD, it would be a different matter...
It would be interesting from a software development perspective to be able to use eigen as a plugin for validation. Note I'm not a Nokia employee, just a commercial licenser of Qt, but I also cannot ship any opensource code wih my products. If Qt uses eigen, then I can't ship it. ----- Original Message ---- From: Benoit Jacob <[email protected]> To: "[email protected]" <[email protected]> Sent: Thursday, May 21, 2009 8:50:09 AM Subject: Re: [Qt4-preview-feedback] 3D enablers : use Eigen library? 2009/5/21 Jason H <[email protected]>: > > Licensing compatability with Qts licenses (not that it matters, this discussion was over, but just replying so people don't get the wrong impression in case Eigen gets considered in the future for something else in Qt) No. Eigen is dual LGPL3+ and GPL2+. Thanks to being LGPL3+-licensed, it can be used by about any software, including LGPL2-licensed software and proprietary software. http://www.gnu.org/licenses/gpl-faq.html#AllCompatibility http://eigen.tuxfamily.org/index.php?title=FAQ Even if Qt wanted to have its own copy of Eigen, it has a special place for third-party software and Eigen would just go there. Moreover we Eigen developers are reachable and can be talked with if there's any concern.
