Hey list, I believe this needs addressing from the BIND team.
> * readline is GPL BIND 9 supports compilation with libedit which is 99% drop-in replacement since 2015 (017cbd44). The well-established open-source distributions are well aware of the readline firm stand on the GPL vs LGPL for the downstream users of the library. > libcap (POSIX capablities) is GPL similarly. No, it’s really not. libcap is 3-clause BSD with following exception added: > ALTERNATIVELY, this product may be distributed under the terms of the > GNU General Public License (v2.0 - see below), in which case the > provisions of the GNU GPL are required INSTEAD OF the above > restrictions. (This clause is necessary due to a potential conflict > between the GNU GPL and the restrictions contained in a BSD-style > copyright.) e.g. the primary license is 3-clause BSD, but in case you need to use libcap in GNU GPL project, you are allowed to do so without considering potential conflicts between 3-clause BSD and GPL 2.0 Cheers, Ondrej -- Ondřej Surý ond...@isc.org > On 11 Jun 2019, at 16:58, Mukund Sivaraman <m...@mukund.org> wrote: > > * readline is GPL, and so you'll link your code to GPL if you link to it > (which can be esp. bad for you if you modify libisc, libdns, > etc. also).
