We are pleased to announce the new release 1.02 of nhc98, a compiler
for Haskell'98, written in Haskell'98.
http://www.cs.york.ac.uk/fp/nhc98/
It is available as a source package (which can be built via ghc, hbc,
an existing nhc98 installation, or simply with a C compiler if you
don't

Summary: Haskell layout has problems within 'do' (see below).
Can we change Haskell to improve it?
I don't think the language has to be changed. It seems to me that the
problems is more with the idea of editing the source code as plain text.
Ideally, I would like

Hi Simon,
Having tried to build 'happy' with the version of GHC I have and having
discovered the GHC system libraries also depend on JMP_, I'm inclined to
think the only "safe" solution is to keep the "if". I can think of no
solution to this; other than enforcing a linking method since without a
I just installed ghc-4.08.2 on a WinNT system.
When I compile Hello World with -O or -prof -auto-all ghc misses a lot of *.h
files (see attached log files).
Note to those who didn't see the attachments: all the missing includes are
from the standard C library.
What can I do?

The problem is indeed that the wrong __init_Foo is being passed to

The Haskell part of your program consists of two modules, Convert and
ConvertProxy (the latter is generated by H/Direct). ConvertProxy
imports Convert, and is therefore the "topmost" module in the program.
To fix

No, that's not it. I've been able to repro this with __init_ConvertProxy
too - did you test it? (This is with 4.08.1 on a Win2k box.)

Hi Andy,
I don't have access to the HP box I built the binaries on at the moment,
so unfortunately I can't investigate right now. Your analysis looks
sound, but like you I'm mystified why we're only now discovering the
problem. Here's one clue: we always pass -static to the C compiler (but

Yes, I did, and was able to demonstrate a crash which went away when

It could be my fault: I ran ./configure before updating it with
autoconf, and perhaps did not clean afterwards.
Ok, it was my fault. But the error in CInfo is still there. And

I installed ghc 4.08.2 binaries for sparc solaris (and those for intel
linux, too), then tried compiling a sample program (the fibonacci one
in the user guide) with ghc -parallel. The compiler complained:

It would not buy anything. You could not make use of the superclass
