3 The (Interactive) Glasgow Haskell Compiler -- version 5.02
4 ============================================================
6 We are pleased to announce a new major release of the Glasgow Haskell
7 Compiler (GHC), version 5.02.
9 This is the first version of GHC that has all of the following:
11 * An interactive read-eval-print loop, similar to Hugs.
12 You can load a mixture of compiled and interpreted modules;
13 in particular, you automatically use the precompiled libraries,
14 so your "interpreted" programs often run pretty fast.
16 * Works solidly on Windows platforms. Installation is simple
17 (Installshield); you don't have to install anything else;
18 and GHC does not get confused if you also happen to
19 have (say) Cygwin installed.
21 * Implements the changes adopted for the (now almost finalised)
22 Revised Haskell 98 Language and Library Reports.
24 * The ability to emit "External Core", a documented typed
25 intermediate language, suitable for slurping up into other
26 tools. [Andrew Tolmach's work.]
28 * A particularly thorough pre-release test programme.
29 Some releases are more solid than others; this one is
30 at the solid end of the spectrum. We fondly hope.
32 So if you have been waiting to upgrade your GHC 4.08, this is
38 The easy way is to go to the WWW page, which should be self-explanatory:
40 http://www.haskell.org/ghc/
42 We supply binary builds in the native package format for various
43 flavours of Linux and BSD, and in InstallShield form for Windows
44 folks. Binary builds for other platforms are available as a .tar.gz
45 which can be installed wherever you want. The source distribution is
46 also available from the same place.
48 Once you have the distribution, please follow the pointers in the
49 README file to find all of the documentation about this release.
52 More details about what's new
53 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
55 5.02 incorporates many small refinements and bug fixes over the previous
56 stable release (5.00.2). There are no major language changes.
58 - Implements Haskell 98 (revised)
60 - Ability to emit External Core. (But GhC can't read External Core
63 - Much improved support for Windows platforms. Binary builds are
64 now entirely freestanding. There's no need to install Cygwin or
65 Mingwin to use it. It's a one-click-install-and-off-you-go story now.
67 - Several small changes to bring GHC into line with the newest Haskell 98
70 - GHCi (the interactive system) now works on Windows.
72 - Partial FFI support in GHCi. At the moment, foreign import (both
73 static and dynamic) is supported on x86 and sparc platforms.
75 - A compacting garbage collector, to try and reduce space use.
77 - Ability to disconnect built-in numeric syntax from the supplied
78 Prelude. This allows you to define your own arithmetic packages,
79 which Haskell98 doesn't quite support.
81 - Experimental: partial support for hierarchical module names.
83 - Experimental: following heroic hacking by Ken Shan, 5.02 now
84 works on Alpha (Tru64 only). Many 64-bit bugs have been shaken
85 out. At the moment only the batch-mode compiler works -- no GHCi
86 or native code generator yet.
88 We've found and fixed more bugs than you could possibly imagine. A
89 big thank-you to all those who reported bugs in the 5.00.X series. We
90 claim to have fixed almost all reported bugs. In general we've spent
91 a large amount of effort trying to improve the stability of the
92 system relative to 5.00.X. (Famous last words ...)

101 Haskell is a standard lazy functional programming language; the
102 current language version is Haskell 98, agreed in December 1998.
104 GHC is a state-of-the-art programming suite for Haskell. Included is
105 an optimising compiler generating good code for a variety of
106 platforms, together with an interactive system for convenient, quick
107 development. The distribution includes space and time profiling
108 facilities, a large collection of libraries, and support for various
109 language extensions, including concurrency, exceptions, and foreign
110 language interfaces (C, whatever). GHC is distributed under a
111 BSD-style open source license.
113 A wide variety of Haskell related resources (tutorials, libraries,
114 specifications, documentation, compilers, interpreters, references,
115 contact information, links to research groups) are available from the
118 http://www.haskell.org/

138 To compile programs with GHC, you need a machine with 64+MB memory, GNU C
139 and perl. This release is known to work on the following platforms:
141 * i386-unknown-{linux,freebsd,mingw32}
144 Ports to the following platforms should be relatively easy (for a
145 wunderhacker), but haven't been tested due to lack of time/hardware:
147 * hppa1.1-hp-hpux{9,10}
148 * i386-unknown-solaris2
151 * {rs6000,powerpc}-ibm-aix
