Needless to say that all these ports got their port revisions bumped.
Was there a good reason for that? I don't know.
I just know that now I need to needlessly reinstall/rebuild about a hundred
ports, many of which are not quite light-weight.
It's time to experiment seriously with ${EXPLICIT_PACKAGE_DEPENDS}
and libtool patch to not link to indirect dependencies
(ports/104877). Ideally a port should include in LIB_DEPENDS all the
direct dependencies.
When I made the EXPLICIT_PACKAGE_DEPENDS patch, I noticed that there
is not only libtool at fault (reaction of the libtool developers was
IIRC: it's not trivial to fix known problems for the cross-building
case (for libtool-1.x?)), but also pkg-config and similar things
(dependencies of dependencies where specified, e.g. your port links
against liba, the pkg-config for liba also told to link against libb
which liba depends upon but for which the ABI was not exposed to your
port by liba, but this caused a record of libb to show up in binaries
of your port). I do not know if the situation improved in _all_ ports,
but some look more sane.
You can also have a look at
/usr/ports/Tools/scripts/explicit_lib_depends.sh, thats a script which
analyzes the recorded dependencies in binaries for a given port (this
may be different from what is recorded in LIB_DEPENDS, and it can be
different from it even if LIB_DEPENDS is 100% correct). So if a lib
which is listed in the output changes the soversion, you _have_ to
recompile this port, no matter if the binary has his hands in the ABI
of the changed lib or not (that's the port->liba->libb case from the
paragraph above).
Bye,
Alexander.
