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 at + + http://www.haskell.org/ + +GHC's Web page lives at + + http://www.haskell.org/ghc/ - * i386-unknown-{linux,solaris2,freebsd,cygwin32} - * sparc-sun-{sunos4,solaris2} - * hppa1.1-hp-hpux{9,10} -Ports to the following platforms should be relatively easy, but -haven't been tested due to lack of time/hardware: +On-line GHC-related resources +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - * alpha-dec-osf{2,3} +Relevant URLs on the World-Wide Web: + +GHC home page http://www.haskell.org/ghc/ +Haskell home page http://www.haskell.org/ +comp.lang.functional FAQ http://www.cs.nott.ac.uk/~gmh/faq.html + + + +System requirements +~~~~~~~~~~~~~~~~~~~ +To compile programs with GHC, you need a machine with 64+MB memory, GCC +and perl.
