As a matter of project policy, the Apache Project does not accept as an official part of software they distribute any software under licenses that place terms upon the larger work. In this case, the terms regarding modification and reverse-engineering we just discussed. However, the Apache license

I'm good with that. I kept running into that scenario. Discussions about GPL but not LGPL. On Thu, Apr 25, 2019 at 3:34 PM Smith, McCoy wrote: > Here’s what FSF says about incompatibility: > https://www.gnu.org/licenses/license-list.html#apache2 > > It discusses GPLv3 (compatible) & GPLv2 (inc

Here’s what FSF says about incompatibility: https://www.gnu.org/licenses/license-list.html#apache2 It discusses GPLv3 (compatible) & GPLv2 (incompatible) but not LGPL. FWIW John Sullivan is looking to update the FSF FAQ and this is issue he might want to write a new FAQ on. Do you mind if I sha

This was the other thing that gave me pause. It expressly says that the LGPL 2.1 is not compatible. http://www.apache.org/legal/resolved.html On Thu, Apr 25, 2019 at 3:25 PM Bruce Perens wrote: > Well, obviously the Apache license permits these things, so no concern > regarding your question.

Well, obviously the Apache license permits these things, so no concern regarding your question. A proprietary license that entirely prohibited modification to the extent of preventing re-linking with a modified LGPL library, or that prevented the reverse-engineering necessary to debug that modific

It's definitely relevant between APL and *GPL*, because GPL places requirements that the terms of the *entire* work do not include restrictions beyond those in the GPL. LGPL doesn't say that. And I didn't completely state all of the requirements of LGPL 2.1 on the non-LGPL piece: *the terms *[must

Yes to both. For the same reasons you could link both to proprietary software. Neither license applies terms to works they are combined with, except for lgpl requiring that it is possible to upgrade or modify the lgpl software and for the combination to be capable of being relinked.
