Hi, Olaf I pushed a PR for libieee1284, so waiting for accept it. https://github.com/alpinelinux/aports/pull/1982
And now I playing with sane-backends building with libpng, libieee1284 and linux-headers as you mentioned. There are some new backends enabled now: canon_pp hpsj5s mustek_pp v4l > I also see that you list the license as GPL in the APKBUILD file. Yes I set GPL as a license for this package and all its subpackages. But I saw its not so simple with some backends licensing. Can you provide me some idea or some list how to describe licensing right way for not-only-gpl parts? Thanks for advise Valery. 2017-07-22 15:52 GMT+03:00 Olaf Meeuwissen <paddy-h...@member.fsf.org>: > Hi Valery, > > I'm one of the SANE developers and am trying to get rid of all compiler > warnings on a select subset of build environments.
