Thanks! - I spent a little trying to build/package it for Fedora, but
running in the usual problem with changes in the library paths/package
keys handling again...

I see that the libraries that come with ghc do not get a package key
unlike those built by hand with Cabal (in the hs-libraries field).
Hence their filepaths also don't include the key any more.  Is this intentional?

I need to update my dependency generation script for the libraries.
However I am less sure how to handle/get the keys or hashes of
dependencies now: is it better to use the id key than the ABI hash?

Quite possible that I missed some earlier discussion, but some light
on this would be appreciated.

Thanks, Jens

ps Please ignore:
If we could stop changing the library file-paths/-names and
hash/key handling so frequently, it would make the life easier for us
distro packagers/maintainers, though I am sure there are a good
reasons for it. :)

I have built a new OS X binary [1] which should be linked against the
in-tree libgmp, fixing this issue (which we've been tracking as Trac
#11423).

I have also pushed a 32-bit Windows build.

Perhaps those affected by this issue could try this distribution?

that using "pkg install library/gmp" command.

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

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

resolve this before the 8.0 release but please let us know if this poses
a significant problem for you.

I would like to nominate

bug I found when using TH with -O, because it currently forces us to
do some production builds with -O0.

Won't help on OS X unless they have Fink installed, and even then that
means potentially getting a different libgmp than base is using.
If base includes libgmp, as it must on Windows / OS X, it should be made
available to other packages.

I'm using Ubuntu precise (12.04LTS). How I know which binary
distribution should install?

I'm asking because I could install without problems both

ghc*x86_64-deb7-linux* and

ghc*x86_64-deb8-linux*.

sudo apt-get install gmp-dev

Installing Cabal and cabal-install (with GHC 7.10.3) from the upstream
repository fixed
the problem.

Ahh yes; I suspected I was missing something in the release
announcement.

Due to unfortunate Cabal/GHC interactions, GHC 8.0 will require
Cabal 0.23. These interface file issues should be cleared up by
wiping your 8.0.1 package database, installing Cabal and cabal-install
0.23 (only available from the upstream repository at the moment), and
trying to install vector again.

The reason for this is a change in how packages are identified in GHC
8.0. While previous versions of Cabal identified packages to GHC with a
package key (with GHC's -this-package-key argument), GHC 8.0 and later uses
another, more specific identifier, the installed package ID. For
compatibility reasons -this-package-key is currently accepted by GHC as
a synonym for -package-name. This is a bit unfortunate, however, as the
two flags aren't really synonymous. This is the reason why cabal-install
fails.

I'm discussing this with Edward Yang and hopefully we'll be able to have
a louder, more obvious failure in place for rc2. I'll be sure to mention
this in future release announcements.

Cheers,

- Ben

You should likely be using the deb8 build in this case. The only
difference is the libc version which is linked against.

I'm guessing this is the same problem with gmp on OS X, but I got it
during the ./configure step, so thought I'd pass along the error
message:

mba:ghc-8.0.0.20160111 xich$ ./configure --prefix=/Users/xich/projects/ghc8

You made reference to the wiki build instructions... do you have a
link to the ones you mean? I can try following them.

The issue here appears to be that the build was compiled against the
host's libgmp on account of the the Wiki build instructions [1] being out of
date. I've fixed this particular inaccuracy, but it would be great if
someone familiar with Darwin could take a close look at this page: do a
build of their own, work through the build instructions, and ensure that 
the build instructions are still accurate, fixing any issues.

George or Carter, perhaps one of you could pick this up?

I think 8.0 requires llvm 3.7 and only supports that version. Are we still

Building from src on a Mac
Not sure why configure script couldn't figure out version of  llvm I have:

checking for llc-3.7... no

checking /usr/local/bin/llc is version 3.7... no
