Note that in addition to the usual complement of Linux/Windows/Darwin

I've noticed that as my tools for producing these distributions improves
the marginal cost of producing another distribution is shrinking. I
would be happy to add OpenBSD as well, but first we'll need to nail
#10032, as far as I understand.
Hi Ben,
the situation on OpenBSD is a little bit lucky than on Solaris since I'm
not sure if this helps, but "system" libffi is in fact installed into
/usr/local from ports and there is no other libffi on OpenBSD and this
by probably lucky coincidence makes GHC working with the only quirk
which is GNU tar complaining about missing header files while making
binary-dist:
"rm" -f bindistprep/ghc-8.2.0.20170507-x86_64-unknown-openbsd.tar
cd bindistprep && "/usr/local/bin/gtar" hcf - -T ../bindist-list |
/usr/local/bin/xz -c >
../bindistprep/ghc-8.2.0.20170507-x86_64-unknown-openbsd.tar.xz
/usr/local/bin/gtar: ghc-8.2.0.20170507/rts/dist/build/ffi.h: Cannot

/usr/local/bin/gtar: ghc-8.2.0.20170507/rts/dist/build/ffitarget.h:

mv bindistprep/*.tar.xz .
anyway, tarbal is generated, it unpacks well, it even install well (with
just ./configure --prefix=<path>; gmake install) and resulting compiler
is working and linked libffi is where it should be:

Hello world!$
so if you like you can give it a try on your OpenBSD. If you are using
latest 6.1 please make sure you build and test on wxallowed mount:
$ pwd
/usr/local/build/karel/ghc-8.2.0.20170507
$ mount
/dev/sd1a on / type ffs (local)
/dev/sd1d on /usr/local type ffs (local, nodev, wxallowed)
otherwise you would get strange "No permission error" while executing
any GHC generated executable including tests run by ./configure. I.e.
OpenBSD starts to be more picky about programs which execute code from
writeable memory page and such security sinners need to be run from
wxallowed paths only. Matthias Killian (cced) has done some work on GHC
to fix that but IIRC he hit the wall somewhere in rts (IIRC) so nothing
from this yet.
Thanks,
Karel
