18:58 mithos28: as long as everyone who wants to use the library wants to release under GPL it works
18:58 mithos28: thats why the GPL is considered viral
18:58 ozzloy: huh
18:59 mithos28: because it forces derivative works to be licensed under the GPL
18:59 (quit) add^_: Quit: The Garbage Collector got me...
19:00 asumu: Another option is just to dual license with GPL and a proprietary license for commercial use.
19:01 asumu: (though this doesn't interoperate with non-copyleft free software)
19:01 mithos28: right, but then you have to get all patches with copyright attribution
19:01 ozzloy: i don't see how that's viral.  you'd have to go out and grab someone else's code.  it's not like it injects itself into your codebase.  and if you're using someone else's code, shouldn't you do it under the terms they're ok with?
19:02 mithos28: ozzloy: It is viral, because if you develop software and want to use a GPL licensed library, your software now has to be GPL'd
19:02 ozzloy: describing that as "bad" takes some gymnastics.  unless you also object to people releasing proprietary software too
19:03 mithos28: it restricts people from using the library, which is why llvm is becoming more popular than gcc for many cases
19:03 ozzloy: mithos28, i get that.  if i use someone else's library, i have to do it on their terms.  i don't see that as bad
19:04 mithos28: My point was that it is bad for you as a library releaser, if you want your library to become used

19:06 mithos28: idk, I think it is GPL
