Added blurb about DocBook environment vars.

Setting up a MacOS X system for building GHC

You will need to install Homebrew for getting some of the tools needed. Homebrew is recommended over other systems on OS X such as MacPorts and Fink.

Xcode (GCC)

For Lion (10.7), Xcode 7.3 or higher

Firstly, you need to install the Xcode Command Line tools from Apple. You can do that in two ways (the second is faster):

  1. Install all of Xcode:
    • Install Xcode from the Mac App Store.
    • Launch Xcode.
    • In the Preference dialog of Xcode, select the "Downloads" pane and install "Command line tools".
  2. Install the command line tools only:

In both cases, you need to register as an Apple developer first (free).

Previous versions of OS X and Xcode

Get the most recent version of Apple's Xcode tools that you can. Your OS X CD has a version on it. You may be able to download a newer version from the Apple Developer Connection website. You may need to sign up for a free membership in the Apple Developer Connection, and downloading may still cost a little money. In later versions of OS X (10.6 / 10.7), Apple added the "App Store". Xcode is available within the App Store for "Free".

Successful builds of older GHC sources have been reported using Xcode 3.0, 2.4 and 2.4.1 on Intel Macs. Xcode 2.2.1 is known not to work out of the box on Intel Macs, and Xcode 3.0 is known not to work out of the box on PowerPC Macs (#2887). Versions prior to 3.1 may build GHC successfully, but choke on certain libraries.

GHC

Secondly, you need a installation of GHC for use as your bootstrap compiler.

You can install a binary distribution of GHC in three ways:

  1. Install the Haskell Platform.
  2. Install via Homebrew: brew install ghc OR brew install haskell-platform.
  3. Install a binary distribution from GHC.

NB: You need to use a binary distribution of GHC 7.4.1 (or later) as your bootstrap compiler.

Other tools

Thirdly, if you want to build the development version of GHC from the Git repositories, you also need to install the GNU auto tools. You can get them as follows:

  • (Homebrew): brew install autoconf automake

Fourthly, if you like to use GHC's LLVM backend:

  • (Homebrew): brew install llvm

Finally, if you want to build the documentation you need to install DocBook. You can install it like so:

  • (Homebrew): brew install docbook

DocBook is a fairly large system unto itself and configuring it to build the documentation in its various formats can be a maze. Verifying that your SGML_CATALOG_FILES and XML_CATALOG_FILES environment variables are pointed at the right places will fix most problems.
