The Glasgow Haskell Compiler -- version 4.08
==============================================
We are pleased to announce a new release of the Glasgow Haskell
Compiler (GHC), version 4.08. The source distribution is freely
available via the World-Wide Web and through anon. FTP; details below.
Haskell is "the" standard lazy functional programming language; the
current language version is Haskell 98, agreed in December 1998.
Haskell related information is available from the Haskell home page at
http://www.haskell.org/
GHC's Web page lives at
http://www.haskell.org/ghc/
+ What's new
=============
This should be a stable release. There have been many enhancements
since 4.06, and shed-loads of bug-fixes (one shed (imperial) ~ one ton
(US)).
There are the following changes
- New profiling subsystem, based on cost-centre stacks.
- Working x86 native code generator: now it works properly, runs
about twice as fast as compiling via C, and is on a par for
run-time speed (except in FP-intensive programs).
- Implicit parameters (i.e. dynamic scoping without the pain).
- DEPRECATED pragma for marking obsolescent interfaces.
- In the wake of hslibs, a new package system for
libraries. -package should now be used instead of -syslib.
- Result type signatures work.
- Many tiresome long-standing bugs and problems (e.g. the trace
problem) have been fixed.
- Many error messages have been made more helpful and/or
accurate.
For full details see the release notes:
http://www.haskell.org/ghc/docs/4.08/users_guide/release-4-08.html
+ Mailing lists
================
We run mailing lists for GHC users and bug reports; to subscribe, send
mail to majordomo@haskell.org; the msg body should be:
subscribe glasgow-haskell-{users,bugs} Your Name <you@where.soever>
or
subscribe cvs-ghc Your Name <you@where.soever>
Please send bug reports about GHC to glasgow-haskell-bugs@haskell.org;
GHC users hang out on glasgow-haskell-users@haskell.org. Bleeding
edge CVS users party on cvs-ghc@haskell.org.
+ On-line GHC-related resources
================================
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
+ How to get it
================
The easy way is to go to the WWW page, which should be
self-explanatory:
http://www.haskell.org/ghc/
Once you have the distribution, please follow the pointers in the
README file to find all of the documentation about this release. NB:
preserve modification times when un-tarring the files (no `m' option
for tar, please)!
+ System requirements
======================
To compile the sources, you need a machine with 32+MB memory, GNU C
(`gcc'), `perl' plus a version of GHC installed (3.02 at least). This
release is known to work on the following platforms:
* i386-unknown-{linux,freebsd,netbsd,cygwin32,mingw32}
* sparc-sun-{sunos4,solaris2}
* hppa1.1-hp-hpux{9,10}
Ports to the following platforms should be relatively easy (for a
wunderhacker), but haven't been tested due to lack of time/hardware:
* i386-unknown-solaris2
* alpha-dec-osf{2,3}
* mips-sgi-irix{5,6}
* {rs6000,powerpc}-ibm-aix
The builder's guide included in distribution gives a complete
run-down of what ports work; an on-line version can be found at
http://www.haskell.org/ghc/docs/4.08/building/building-guide.html
