Re: ANNOUNCE: GHC version 7.8.1

Dominick, I don't know what error you ran into, but here are a few tips: * The "network" package requires configure, so you will likely need to install it from an MSYS prompt. * Make sure your existing cabal executable is version 1.18 or higher. Execute `cabal --version` and `ghc --version` to make sure older versions are not being found. Because of the way Windows handles paths you may have to specify the full path to cabal.exe * Delete your %appdata%\ghc and %appdata%\cabal folders, then run `cabal update`. This will clear out any previous cabal packages you may have already installed. On Wed, Apr 9, 2014 at 8:23 AM, Dominick Samperi wrote:

Thank you Austin!

I unpacked the Windows 64bit distribution and tried to update cabal as instructed, but got this: Registering zlib-0.5.4.1... cabal: Error: some packages failed to install: HTTP-4000.2.12 depends on network 2.4.2.2 which failed to install. network-2.4.2.2 failed during the configure step.

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 good 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 (C, whatever). 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/TeamGHC

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://www.haskell.org/mailman/listinfo/glasgow-haskell-users http://www.haskell.org/mailman/listinfo/glasgow-haskell-bugs

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

http://www.haskell.org/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:
