- Tell octave-forge* users to completely remove old ports before
reinstalling.
This is not the first time this issue (ports doing the wrong thing if
you try to build them while they are installed) has come up, and I've
been thinking ... do we need something like a NO_REINSTALL flag that can
be added to a port's Makefile to indicate the problem? I realize that in
many cases the problem is better solved by fixing the real problem.
However I think that there are likely situations like this where there
is a legitimate problem that can only be overcome by removing the
installed ports first.
Is this idea worth pursuing? I have some ideas about how it should be
implemented but I'm curious what others think about the concept first.
I don't think it's useful. IMO Ports failing to build if their ancestor
is installed are buggy (usually they set wrong CPPFLAGS and LDFLAGS and
pick up system-wide before local #includes) and should be fixed. I am
concerned that such a flag would only be abused as a sort of "I don't
mean to fix the port" marker.
Stephen has (according to his replies here in this thread) done the
right thing and fixed them.
My problem was slightly different. I had a case where A depended upon
B, and then if the user did "pkg_delete -f B" and then reinstalled B,
then A would not work. Because of the particulars of my situation, it
was not trivial to fix this.
(The situation was a bit like B=print/teTeX-texmf and A=print/latex-pgf.
In this situation, there is a script called mktexlsr which solves the
problem. I had to create a similar script to mktexlsr, only in this
case the script was a bit more complicated.)
Also, I never use tools like portmaster. When I update, I do something
like "pkg_delete -r B" and then reinstall A, knowing it will pick up B
as a prerequisite. So I only became aware that my ports were
problematic when I was contacted by a user who told me they weren't
working with portmaster.
I had always assumed that the "-f" option to pkg_delete was something to
be avoided. But tools like portmaster use it as a matter of course, and
my assumption was proved incorrect.
