Great! Let me know if you find any other issues.

Thanks George.

I would like to nominate
https://ghc.haskell.org/trac/ghc/ticket/11172, the run-time segfault
bug I found when using TH with -O, because it currently forces us to
do some production builds with -O0.

Happy to provide more input/testing in the ticket if needed.

You should be able to use `-O -fno-cse` (at least that worked last time I
checked).

Possibly. The logistics of this still need to be worked out.

Indeed this should be fixed. Thanks!

This is pretty standard but it wouldn't hurt to mention it.

GHC 8.0 Migration Guide & Ubuntu GHC8/cabal packages (was: [ANNOUNCE] Glasgow Haskell Compiler 8.0.1, release candidate 1)

As this wasn't explicitly mentioned in the announce, I'd like to point
your attention to

 https://ghc.haskell.org/trac/ghc/wiki/Migration/8.0

which would benefit greatly from early adopters. More importantly, this
helps us all to reduce the boring & redundant investigative work of
rediscovering the same migration techniques by multiple parties over and
over again... :-)



I'd also like to remind you that (more or less) daily snapshots of GHC 8.0.1 for
Ubuntu {Precise,Trusty,Vivid,Wily} are already available via

  https://github.com/hvr/multi-ghc-travis

This also includes a "cabal-install-1.24" package (which currently
contains the current latest devel snapshots of cabal-install soon to
become version 1.24)

This specifically allows you to integrate GHC 8.0.1 & cabal-install 1.24
into your test-matrices in the `travis.yml` files, and thereby help
detect GHC 8.0 & Cabal 1.2[34] issues early on. The new packages have
been whitelisted for containerised Travis jobs already.

Cheers,
  hvr

Hi,

I've build two builds for Solaris 11.2:

i386: https://app.box.com/s/1m75kzunzsz6bqh77py5517t39734446
amd64: https://app.box.com/s/y583zs1tqduz8lbppt66z1qlxms0vytg

Both binary distributions support shared libraries and use system
provided GMP library. If you do not have it installed then you should do
that using "pkg install library/gmp" command.


and one build for OpenBSD 5.9 (current):

amd64: https://app.box.com/s/95lpdhoc5h0zs0mx3chlacdl3hskzkqi

This binary distribution also supports shared libraries and by default
also OpenBSD position independent executables (PIE). It requires gmp,
libffi and libiconv to be installed by "pkg_add " command.


SPARC build for Solaris 11.2 is ongoing.

The GHC Team is very pleased to announce the first release candidate of
the Glasgow Haskell Compiler 8.0.1 release. Source and binary
distributions as well as the newly revised users guide can be found at

 http://downloads.haskell.org/~ghc/8.0.1-rc1/

This is the first in a series of release candidates which will allow us
to get wider testing of the significant changes that have occurred since
the 7.10 series. These include,

  * the TypeInType extension, which unifies types and kinds allowing for
promotion of more Haskell constructs to the type-level

  * the introduction of type application in source programs

  * support for recursive superclass relationships

  * support for Applicative do notation

  * introduction of the DuplicateRecordFields language extension

  * a rewritten and substantially more thorough pattern match checker

  * the introduction of injective type classes

  * introduction of the Strict and StrictData language extensions,
allowing modules to be compiled with strict-by-default evaluation
of bindings

  * the ability to run the GHCi interpreter in a separate process,
allowing a callstacks in GHCi, easier integration with tooling, and
more

and much more.

Changes of this magnitude will invariably bring bugs. This release
candidate in particular is known to suffer from a few significant issues
which are being actively worked upon,

  * The new -XInjectiveTypeFamilies language extension will likely be
renamed to -XTypeFamilyDependencies

  * #11120: Type representations are missing for some types and promoted
constructors

  * #11334: Solving for Typeable (Proxy :: Proxy 'Compose) fails

  * #11276: Pattern checker performance can degrade significantly in
presence of pattern matches with guards

  * #11405: Type-level skolem-escape check fails incorrectly

  * #11414: Use of -XStrict results in compiler abort

  * #11379: Instance solver fails to terminate

  * #11419: Haddock documentation is currently not included in the binary
distributions (and hence is missing on downloads.haskell.org)

  * #11370: -Wredundant-constraints being included in -Wall breaks
the three-release compatibility policy

In the coming weeks we will continue to iterate on these issues. We will
also look at Trac tickets marked with "highest" priority on the release
status page [2].

If you have a ticket that you would like to see addressed that does not
meet one of these criteria, please bring this to our attention.
Likewise, if you encounter an issue please open a ticket if one does not
already exist.

Also note that we currently cannot offer 32-bit Windows builds due to
breaking changing in a recent Windows 10 upgrade. We'll work to
resolve this before the 8.0 release but please let us know if this poses
a significant problem for you.

Cheers,

- Ben

For the FreeBSD users, I have built the vanilla binary distributions.
They are available here, along with a brief installation guide:
