nhc98-1.14 + hmake-3.05
-----------------------
We are pleased to announce new releases of nhc98 and hmake. These are
essentially bug-fix and performance-improvement releases.
hmake:
* Bugfixes for the -hat option
nhc98:
* No longer includes Hat, the Haskell'98 tracing system. Hat will
shortly be released as a separate package, capable of working
with either nhc98 or ghc, or both.
* Tracks the latest minor revisions of the Haskell'98 Report.
* Runtime performance improved by 8% (thanks to Thomas Nordin).
* Numerous other small tweaks and bugfixes.

hat-2.00
------------------------------------
We are pleased to announce a new release of Hat, the Haskell tracing
(an debugging) system for Haskell'98.
This release of Hat is a major release. It is now distributed entirely
separately from the nhc98 compiler, and supports both nhc98 and GHC as
possible host compilers.
Since the last release of Hat, the trace file format has changed,
the browsing tools have been substantially rewritten for better
cross-tool integration, and runtime performance has been improved.
If you haven't already tried out the Hat tracing system, now is a
good time to have a go! Features worth noting are:
* There is a tutorial introduction to Hat, showing how to generate
program traces, how to explore them, and how they can help you
to debug Haskell programs.
* All the interactive trace browsing tools are implemented in
Haskell, including a simpler, textual version of hat-trail.
They all inter-operate, and use a similar command syntax.
* The trace-generating machinery can be used with either GHC or
nhc98. Just use `hmake -ghc -hat' or `hmake -nhc98 -hat'.
There is a new mailing list at haskell.org for discussion of the Hat
system, and bug-reports.
http://haskell.org/mailman/listinfo/hat

For hat downloads: ftp://ftp.cs.york.ac.uk/pub/haskell/hat/
(Please note that a prior installation of hmake-3.05 is required.)

Hello, I'm not subscribed to this list, so please make sure you CC to me
if you reply.
I just installed nhc98 (from source) and tried to compile a simple
program:
module Test where
main = return ()
Here is the result:
$ nhc98 test.hs
/usr/lib/nhc98/ix86-Linux/Prelude.a(_Driver.o)(.data+0x88): undefined
reference to `CF_Main_46main'
collect2: ld returned 1 exit status
$
This is the first "program" I've tried to write in Haskell (although
I've used Clean and Miranda before). Did I do something wrong??
