gregory,
thanks for your kind reply. sorry for responding so late but I was OOO
(Out Of Office).
Hi Joerg,
This problem is almost certainly bug #751.
This gives a compiler crash if the threaded run time system
is used. The latest darwinports ghc (which I maintain) builds
the run time without threads. What is the output of
sudo port info ghc
?
If you do not have revision 2 of the 6.4.2 portfile, you need to
update:
sudo port selfupdate
`port info ghc reported that it was _not_ revision 2 and so I did the
`selfupdate' as advised. this went OK. I then did
sudo port upgrade ghc
but this did not go so well:
after some fetching/compiling it crashed and a second try yielded:
---> Activating ghc 6.4.2_0+darwin_8
---> Activating readline 5.0.005_0+darwin_8
---> Deactivating readline 5.0.005_0+darwin_8

Command output: make: *** No rule to make target `all'. Stop.
as in the first attempted `upgrade' the problem seemed to be the
unability to fetch readline51-001 from any site.
what is a poor guy to do? where is(are) my fault(s)? up to now I've been
'fully elastically reflected' by ghc :-(
all the best
joerg
If you are running the latest version, your experiences
are... interesting.
Best Wishes,
Greg

hi,
my very first tries with ghc, using the 'program'
module Fact where
fact :: Integer -> Integer
fact n = product [1..n]
gave the following compiler crash under MacOS X 10.4.7 (ghc installed
from source via DarwinPorts):

Please report this as a compiler bug. See:
http://www.haskell.org/ghc/reportabug
more irritating, this error was _not_ reproducible. a second try did
run through:
`ghc -c fact.hs' yielded a file `fact.o'
but `ghc -o fact fact.o' yielded:
/usr/bin/ld: Undefined symbols:

and `ghc -v --make fact' yielded

hope this helps in one way or the other
