Help with macports port for zef
Hi. I'm trying to create a macports portfile for zef so
that macports users can easily install zef using
macports. Currently, the only raku-related port on
macports is rakudo itself (and nqp). A zef port would
be a great next step. But I'm not a raku expert or a
macports expert, so I need help.
I did manage to get it to successfully test and install
and activate, but only once. When I then tried to
install using certain options (-vst) that show you
which assumptions you've made that won't be true for
others, I started getting an error. And the error never
went away even without -vst. I'm hoping someone here
might be able to explain what's happening.
In case anyone here uses macports and can test this
themselves, the broken portfile is at
https://github.com/macportsraf/raku-zef-portfile
The error is that it's failing to mkdir
/opt/local/share/perl6/site/short (Operation not
permitted). Currently, /opt/local/share/perl6/site only
contains "version". It shouldn't be placing anything
directly in /opt/local at this stage (the "destroot"
stage). It should be installing into a DESTDIR
location. The command used to install zef into the
destroot is:
"${prefix}/bin/rakudo" -I"${worksrcpath}" bin/zef
--to="inst#${destroot}${prefix}/share/perl6/site" install "${worksrcpath}"
which shouldn't be touching /opt/local. Nothing can
affect /opt/local (i.e. ${prefix}) until the port is
installed and activated). Installation is into a
version-specific directory, and activation of a
particular version copies files from that directory
to the official "prefix" (usually /opt/local).
the "destroot" phase happens before all of that
into a temporary directory.
Perhaps rakudo is doing some housekeeping in addition
to what zef is trying to do to install itself? Does
anyone have any idea what might be causing this mkdir,
and is there anything I can do to suppress it?
Alternatively, if rakudo is creating directories that
it sees as missing, can I preempt that by triggering
those directories to be created earlier when rakudo
itself is installed, so that it doesn't feel the need
to do it when something else is being installed later?
cheers,

I have been given good advice on how to proceed with my problem (that some directories aren't created when rakudo is installed, so it tries to create them when running zef's installation but not having the permissions to do so). But I'm too busy at the moment to work on it right now. Macports builds a package into a destroot directory and then installs it into an installation directory and then activates the installation by copying or symlinking from /opt/local/whatever to the installation directory. That enables multiple versions of the same package to be installed, with a single version being active at any one time. I think the problem I'm having is that it disregards empty directories unless you explicitly instruct it to keep them, and I think that that isn't happening in the rakudo port to retain directories that it creates but that are empty initially. If I change the rakudo port to keep those directories, the zef port should work. At least, that's my mental model at the moment. cheers, raf
