Well, OpenBSD 6.1 is almost dead, 6.2 is the stable release at the
moment, and 6.3 will probably be released in about two months. For
6.2 the default C compiler is clang-4.0.0, for 6.3, it will be at
least clang-5.0.1 (at least on i386 and amd64 platforms).

So, providing ghc binaries for 6.1 at all would be mostly pointless,
anyway (there will be no support for 6.1 from the moment 6.3 has
been released).

Ciao,
        Kili

ps: whoever is doing binary releases of ghc for OpenBSD (I only
know about Karel Gardas pushing patches from our ports tree from
time to time) could use a newer gcc or clang from ports/packages
if it helps. Of course, if time permits (and as the defacto maintainer
of lang/ghc on OpenBSD I know how time consuming this can be ;-))

Thanks for the clarification! This is very helpful.

Indeed that is me. There is a bit more to the story of why we have no
OpenBSD builds: In short, I don't actually have a machine running
OpenBSD. Usually I spin up a virtual machine locally to produce
distributions for distributions which I don't myself run. However, this
time I had quite some trouble bringing up an OpenBSD VM (the
installation image appeared to hang shortly after booting when running
on QEmu/kvm on both Intel and AMD hardware).

Lacking any way to produce a build locally, I turned to AWS, which only
has an AMI for OpenBSD 6.1.

Cheers,

- Ben

Hi!

It says on the download page that the Windows versions is “excluding the Windows 10 Creator’s Update”. I’m assuming that is a copy-paste error from the release that fixed the Windows 10 CU bug.

Niklas

Good catch; in principle this should now be automatically generated.
I'll need to look at what has gone wrong here. I've opened #14906 to
track this.

Ahh, thanks; I've added this to the MakingReleases protocol [1] to
ensure that this is done in the future.

Yes, the Hackage uploads have historically not been handled by me but
rather Herbert. He know about the release and am certain has the task on
his queue.

Cheers,

Thanks!

I have built it for Fedora and EPEL7 in a copr repo:
