[ANNOUNCE] GHC 8.4.1 released

Ben Gamari-3

The GHC developers are very happy to announce the 8.4.1 release of
Glasgow Haskell Compiler. Binary and source distributions can be found
at

    https://downloads.haskell.org/~ghc/8.4.1/

This is the third major release in the GHC 8 series. As such, the focus
of this release is performance, stability, and consolidation.
Consequently numerous cleanups can be seen throughout the compiler
including,

 * Further refinement of TypeInType, including significant improvements
   in error messages.

 * Improvements in code generation resulting in noticable performance
   improvements in some types of programs.

 * Core library improvements, including phase 2 of the Semigroup/Monoid
   proposal

 * Many improvements to instance deriving

 * The resolution of nearly 300 other tickets

A more thorough list of the changes in this release can be found in the
release notes,

  https://downloads.haskell.org/~ghc/8.4.1/docs/html/users_guide/8.4.1-notes.html

There are a few changes in release-engineering matters that should be
noted,

 * This is GHC's first release on it's new, accelerated release
   schedule. From now on GHC will produce one release every six months.

 * While we typically strive to produce OpenBSD builds, the gcc shipped
   with OpenBSD 6.1 is unfortunately too old to compile this release.

 * FreeBSD builds are still in progress

This release has been the result of approximately six months of work by
over one hundred code contributors. Thanks to everyone who has helped in
writing patches, testing, reporting bugs, and offering feedback over the
last year.

As always, let us know if you encounter trouble.


How to get it
~~~~~~~~~~~~~

The easy way is to go to the web page, which should be self-explanatory:

        http://www.haskell.org/ghc/

We supply binary builds in the native package format for many
platforms, and the source distribution is available from the same
place.

Packages will appear as they are built - if the package for your
system isn't available yet, please try again later.


Background
~~~~~~~~~~

Haskell is a standard lazy functional programming language.

GHC is a state-of-the-art programming suite for Haskell.  Included is
an optimising compiler generating efficient code for a variety of
platforms, together with an interactive system for convenient, quick
development.  The distribution includes space and time profiling
facilities, a large collection of libraries, and support for various
language extensions, including concurrency, exceptions, and foreign
language interfaces. GHC is distributed under a BSD-style open source license.

A wide variety of Haskell related resources (tutorials, libraries,
specifications, documentation, compilers, interpreters, references,
contact information, links to research groups) are available from the
Haskell home page (see below).


On-line GHC-related resources
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Relevant URLs on the World-Wide Web:

GHC home page              http://www.haskell.org/ghc/
GHC developers' home page  http://ghc.haskell.org/trac/ghc/
Haskell home page          http://www.haskell.org/


Supported Platforms
~~~~~~~~~~~~~~~~~~~

The list of platforms we support, and the people responsible for them,
is here:

   http://ghc.haskell.org/trac/ghc/wiki/Contributors

Ports to other platforms are possible with varying degrees of
difficulty.  The Building Guide describes how to go about porting to a
new platform:

    http://ghc.haskell.org/trac/ghc/wiki/Building


Developers
~~~~~~~~~~

We welcome new contributors.  Instructions on accessing our source
code repository, and getting started with hacking on GHC, are
available from the GHC's developer's site run by Trac:

  http://ghc.haskell.org/trac/ghc/


Mailing lists
~~~~~~~~~~~~~

We run mailing lists for GHC users and bug reports; to subscribe, use
the web interfaces at

    http://mail.haskell.org/cgi-bin/mailman/listinfo/glasgow-haskell-users
    http://mail.haskell.org/cgi-bin/mailman/listinfo/ghc-tickets

There are several other haskell and ghc-related mailing lists on
www.haskell.org; for the full list, see

    https://mail.haskell.org/cgi-bin/mailman/listinfo

Some GHC developers hang out on #haskell on IRC, too:

    http://www.haskell.org/haskellwiki/IRC_channel

Please report bugs using our bug tracking system.  Instructions on
reporting bugs can be found here:

Re: [ANNOUNCE] GHC 8.4.1 released

Haskell - Glasgow-haskell-users mailing list
Hello,

I tried to compile the latest bits on OpenIndiana (the open version of Solaris) and
compilation never starts because:

checking target system type... i386-pc-solaris2.11
Build platform inferred as: i386-unknown-solaris2
Host platform inferred as: i386-unknown-solaris2
Target platform inferred as: i386-unknown-solaris2
Unknown OS solaris2.11

The configure script mentions Solaris... On my system
I get

$ uname -m
i86pc
$ uname -r
5.11
$ uname -s
SunOS
$ uname -v
illumos-87446a5213

Any idea that migh help me go beyond this point?

Thanks in advance!

A.S.

Oh dear, yes. Thank you for noticing this.

I saw there is ARM Aarch64 build, which is pretty cool! But will there be a ARMv7 (32bit build) as well?

I do hope so. There have been a number of false-starts but hopefully the
build that is currently running will finish. Unfortunately getting a
working ARMv7 build is rather tricky due to a number of linker bugs that
bite under various circumstances.

Cheers,
