1 The Glasgow Haskell Compiler
2 ============================
4 This is the source tree for GHC, a compiler and interactive
5 environment for the Haskell functional programming language.
7 For more information, visit GHC's web site:
9 http://www.haskell.org/ghc/
11 Information for developers of GHC can be found here:
13 http://hackage.haskell.org/trac/ghc/
19 First get the GHC darcs repository:
21 $ darcs get http://darcs.haskell.org/ghc/
23 Then run the darcs-all shell script in that repository
24 to get the other repositories:
29 This grabs the "core" packages by default. To get the full set of
30 packages (which will probably take a long time to build), instead say
32 $ sh darcs-all --extra get
38 NB. you need GHC installed in order to build GHC, because the compiler
39 is itself written in Haskell. It is possible to build GHC using just
40 a C compiler, but we don't recommend this as the normal route. If you
41 *really* want to do it this way, then see the Building Guide (link
44 You also need a few other tools installed: Happy [4], Alex [5], and
45 Haddock [6] (for building library documentation), and a good DocBook
46 XML toolchain if you want to build the compiler documentation.
48 Quick start: the following gives you a default build:
55 The autoreconf step is only necessary if this is a tree checked out
56 from darcs. For source distributions downloaded from GHC's web site,
57 this step has already been performed.
59 These steps give you the default build, which includes everything
60 optimised and built in various ways (eg. profiling libs are built).
61 It can take a long time. To customise the build, see the file
64 For full information on building GHC, see the GHC Building Guide [3],
65 which is also available in source form (DocBook XML) in docs/building.
