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 
stat: No such file or directory
/usr/local/bin/gtar: ghc-8.2.0.20170507/rts/dist/build/ffitarget.h: 
Cannot stat: No such file or directory

/usr/local/bin/gtar: Exiting with failure status due to previous errors
mv bindistprep/*.tar.xz .


anyway, tarbal is generated, it unpacks well, it even install well (with 
just ./configure --prefix=; 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

GHC 8.2.1-rc2 source tarball availability

[Ben Gamari]

tl;dr: If you would like to produce a binary distribution for GHC
   8.2.1-rc2 then let me know, grab the source distribution and
   start building. The binary distributions will be announced one
   week from today.


Hello GHC packagers,

I am happy to announce the release of the 8.2.1-rc2 source distribution
to binary packagers. You will find the usual source artifacts at

http://downloads.haskell.org/~ghc/8.2.1-rc2/

As usual, the sooner we can get the binary distributions together the
better, but I will hold off on announcing the distributions until next
Sunday to ensure we're all on the same page. It would be appreciated if
you could reply to this message confirming that you intend to offer a
binary distribution this release.

Otherwise, let me know if you have any trouble building your
distribution. I have yet to push the ghc-8.2.1-rc1 tag in case we
encounter unexpected issues but all of my builds with this tarball
thusfar have gone well.

Note that in addition to the usual complement of Linux/Windows/Darwin
bindists, I have also produced a FreeBSD distribution this time around.
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.

Good luck and thanks for all of your work!

Cheers,

- Ben
