./configure tries to update CFLAGS/LIBS with LIBNL3_CFLAGS/LIBS using '+=':
checking for LIBNL3... yes
./configure: line 14545: CFLAGS+= -I/usr/include/libnl3 : not found
./configure: line 14546: LIBS+= -lnl-genl-3 -lnl-3 : not found
so later build fails without proper libnl3 flags:
nbd-client.c:51:10: fatal error: netlink/netlink.h: No such file or directory
#include <netlink/netlink.h>
nbd-3.18 suffers from the same problem.
This commit updates $license variable in all APKBUILDs to comply with
short names specified by SPDX version 3.0 [1] where possible. It was
done using find-and-replace method on substrings inside $license
variables.
Only license names were updated, not "expressions" specifying relation
between the licenses (e.g. "X and Y", "X or Y", "X and (Y or Z)") or
exceptions (e.g. "X with exceptions").
Many licenses have a version or multiple variants, e.g. MPL-2.0,
BSD-2-Clause, BSD-3-Clause. However, $license in many aports do not
contain license version or variant. Since there's no way how to infer
this information just from abuild, it were left without the variant
suffix or version, i.e. non SPDX compliant.
GNU licenses (AGPL, GFDL, GPL, LGPL) are especially complicated. They
exist in two variants: -only (formerly e.g. GPL-2.0) and -or-later
(formerly e.g. GPL-2.0+). We did not systematically noted distinguish
between these variants, so GPL-2.0, GPL2, GPLv2 etc. may mean
GPL-2.0-only or GPL-2.0-or-later. Thus GNU licenses without "+" (e.g.
GPL2+) were left without the variant suffix, i.e. non SPDX compliant.
Note: This commit just fixes format of the license names, no
verification has been done if the specified license information is
actually correct!
