Hi Magnus
The 'Why not LGPL' doesn't cover the particular argument here:
using the ordinary GPL for a library makes it available only for free programs.
The particular concern we have here is quite specific, considering (-->) to be a dependency, can Hackage libraries under BSD3 that depend on libraries under GPL?
[1] App --> libBSD3 --> libGPL
Any App built has to incorporate the GPL library - so the App has to be GPL. -- No dispute --.
Similar BSD3 is a GPL compatible library, so this dependency chain would be legal:
[2] App --> libGPL --> libBSD
The argument is whether it is legal to distribute (read host on Hackage) BSD3 libs that depend on GPL libs - formulation [1].
Now I'm even more confused. How is hosting on Hackage an issue in [1]? Both involved licenses are very liberal when it comes to distribution. The only issue I do see is that the author of libBSD3 is actually deluding her/him-self, since the use of libGPL means both libraries are in fact under GPL. I don't see this being anything that anyone involved with Hackage can be held responsible for, the responsibility must fall on the author of libBSD3. In this scenario I don't see Hackage as anything more than a conduit. /M -- Magnus Therning (OpenPGP: 0xAB4DFBA4) magnus＠therning．org Jabber: magnus＠therning．org http://therning.org/magnus identi.ca|twitter: magthe
