1 The Glasgow Haskell Compiler -- version 4.08
2 ==============================================
4 We are pleased to announce a new release of the Glasgow Haskell
5 Compiler (GHC), version 4.08. The source distribution is freely
6 available via the World-Wide Web and through anon. FTP, under a
7 BSD-style license. See below for download details. Pre-built
8 packages for Linux, FreeBSD, Solaris and Win32 are also available.
10 Haskell is "the" standard lazy functional programming language; the
11 current language version is Haskell 98, agreed in December 1998.
13 GHC is a state-of-the-art optimising compiler for Haskell, generating
14 good code for a variety of platforms. The distribution includes space
15 and time profiling facilities, a large collection of libraries, and
16 support for various language extensions, including concurrency, exceptions,
17 and foreign language interfaces (C, C++, whatever).
19 A wide variety of Haskell related resources (tutorials, libraries,
20 specifications, documentation, compilers, interpreters, references,
21 contact information, links to research groups) are available from the
24 http://www.haskell.org/
26 GHC's Web page lives at
28 http://www.haskell.org/ghc/
33 This should be a stable release. There have been many enhancements
34 since 4.06, and shed-loads of bug-fixes (one shed (imperial) ~ one ton
37 There are the following changes
39 - New profiling subsystem, based on cost-centre stacks.
41 - Working x86 native code generator: now it works properly, runs
42 about twice as fast as compiling via C, and is on a par for
43 run-time speed (except in FP-intensive programs).
45 - Implicit parameters (i.e. dynamic scoping without the pain).
47 - DEPRECATED pragma for marking obsolescent interfaces.
49 - In the wake of hslibs, a new package system for
50 libraries. -package should now be used instead of -syslib.
52 - Result type signatures work.
54 - Many tiresome long-standing bugs and problems (e.g. the trace
55 problem) have been fixed.
57 - Many error messages have been made more helpful and/or

104 + System requirements
105 ======================
107 To compile programs with GHC, you need a machine with 32+MB memory, GNU C
108 and perl. This release is known to work on the following platforms:
110 * i386-unknown-{linux,freebsd,netbsd,cygwin32,mingw32}
112 * hppa1.1-hp-hpux{9,10}
114 Ports to the following platforms should be relatively easy (for a
115 wunderhacker), but haven't been tested due to lack of time/hardware:
117 * i386-unknown-solaris2
120 * {rs6000,powerpc}-ibm-aix
122 The builder's guide included in distribution gives a complete
123 run-down of what ports work; an on-line version can be found at
