GHC 5.02.1 is available. Currently the source, x86-linux and
sparc-solaris tarballs are available. We hope to add binary
builds for Win32 and Alpha early next week. -- J
The (Interactive) Glasgow Haskell Compiler -- version 5.02.1
We are pleased to announce a new patchlevel release of the Glasgow
Haskell Compiler (GHC), version 5.02.1. The source distribution is
freely available via the World-Wide Web, under a BSD-style license.
See below for download details. Pre-built packages for Linux,
FreeBSD, Solaris and Win32 are also available.
Haskell is a standard lazy functional programming language; the
current language version is Haskell 98, agreed in December 1998.
GHC is a state-of-the-art programming suite for Haskell. 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, C++, whatever).
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
GHC's Web page lives at
What's new in 5.02.1
Fixed various bugs, some of which caused GHCi to crash or misbehave.
Some documentation fixes. Nothing major.
What's new in 5.02
5.02 incorporates many small refinements and bug fixes over the previous
stable release (5.00.2). There are no major changes. =20
- Much improved support for Windows platforms. Binary builds are
now entirely freestanding. There's no need to install Cygwin or
Mingwin to use it. It's a one-click-install-and-off-you-go story
- Several small changes to bring GHC into line with the newest
- GHCi (the interactive system) now works on Windows.
- Partial FFI support in GHCi. At the moment, foreign import (both
static and dynamic) is supported on x86 and sparc platforms.
- A compacting garbage collector, to try and reduce space use.
- Experimental: partial support for hierarchical module names.
- Experimental: following heroic hacking by Ken Shan, 5.02 now
works on Alpha (Tru64 only). Many 64-bit bugs have been shaken
out. At the moment only the batch-mode compiler works -- no GHCi
or native code generator yet.
We've found and fixed more bugs than you could possibly imagine. A
big thank-you to all those who reported bugs in the 5.00.X series. We
claim to have fixed almost all reported bugs. In general we've spent
a large amount of effort trying to improve the stability of the
system relative to 5.00.X. (Famous last words ...)

To compile programs with GHC, you need a machine with 64+MB memory, GNU
and perl. This release is known to work on the following platforms:
Ports to the following platforms should be relatively easy (for a
wunderhacker), but haven't been tested due to lack of time/hardware:

run-down of what ports work; an on-line version can be found at
