Hi,

libieee1284 is accepted, so I push a asne-backends PR with improvements

I noticed that was accepted.

As for the CI builds, I think I'll stick to using linux-headers only so
I have a bit more diversity in the way sane-backends gets build.

Indeed.

For starters, I would use the LICENSE file as a guide.

So the frontends are GPL-2.0+ and the API spec is public domain.  As for
the backends, *most* are GPL-2.0+ with exception.  The ones that are not
are, IIRC, GPL-2.0+.  BTW, I'm not sure whether the exception is exactly
the same for all backends.

A long while back I actually analysed the situation (at the office) but
I don't have access to the results anymore (assuming they still exist).
What might be one way of recourse is the debian/copyright file (from the
Debian/Devuan/Ubuntu packages).  These contain a machine processable
"bill of rights" and are normally quite carefully vetted (at least the
first time around).

It's a bit old (1.0.24!), but I've attached the one that came with my
Devuan libsane package for reference.

You're welcome.

FTR, I did take the easy way out (but may want to look at disabling the
umax_pp backend if it's just going to no-op).

Hope this helps,

Re: [sane-devel] Getting Alpine Linux sane-backends builds compiler warning free

[Valery Kartel]

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.
