Hi
I just installed ghc-4.08.2 on Windows NT. I tried the following program
module Main where
import System
main = do
argv <- getArgs
case argv of
(inp:out:[]) -> do
contents <- readFile inp
writeFile out contents
_ -> putStr "usage_msg "

Hi
I think that there's a bug in dupChan in
Chan.lhs
I tried the following program.
main = do chan <-
newChan ch <- dupChan chan writeChan chan "done" x
<- readChan chan y <- readChan ch prnt ("Got "++x ++"
"++y)
Now if I remember correctly this should print "Got
done done".

Hi
I installed ghc-4.08.1 earlier today on a Windows
NT box. I tried out hello world. I compiled with:
ghc -O -static -o main Main.hs
Compilation went fine. But when I tried to run the
program it produced no output. I then experimented further. I got TclHaskell
up & running and successful
Hi,
I've got the following program. It depends heavily on finalisers being run
regularly as it goes along. I therefore call yield regularly to try to
ensure this.
This works perfectly under the original ghc-4.04 release, weak pointers are
garbage collected and finalisers run regularly.
However, w
Hi I compiled up the cvs ghc from yesterday (7 Dec 1999). This was on NT.
I had one problem when actually compiling.
In config.mk.in line 150 has been changed to:
WithGhcHc = $(HC)
from
WithGhcHc = @WithHc@
This caused circular dependencies when compiling up ghc/compiler.
Hi
I compiled up the attached set of files using Tuesday's cvs ghc. It's
compiled with -prof -auto-all -caf-all. It runs fine without heap profiling,
but core dumps with it. This was running on windows NT.
I ran it with the following arguments:
main 1000 +RTS -h

Hi
When compiling the cvs ghc and hslibs from Nov 30 I found the following
problem.
Compiling hslibs/util/Select.lhs failed because it imported posix interface
files.

Hi,
I got round yesterday's compilation problem (panic on interface file), by
compiling the module Widgets.lhs without -O.
The demo program now compiles.
It runs normally and will happily give a time profile.
./demos +RTS -pT
However, when run with heap profiling
./demos +RTS -hC
it crashes wit
Hi,
I tried compiling a cvs copy of ghc from Monday 22 November.
This was on Windows NT. The compiler was compiled using the binary
ghc-4.045 binary release. It crashed when compiling PrelBase.

Thanks, that fixed the initial problem but now I've got another one.

The instruction at "0x77f6ce0c" referenced memory at "0x0010". The

This happened with me, with ghc-2.04 aswell. Sigbjorn said
"the backend is trying to steal more x86 registers than gcc can handle".
The solution is to do the following, compile ArrBase separately using:
make EXTRA_HC_OPTS=-monly-2-regs ghc/ArrBase.o
Then go on with the mak

What compiler flags am I missing, that I need, to get this to work?
Sorry if I'm missing something obvious.

There's a bug in the signalQSemN function in the
Semaphore module. (In versions ghc-0.29 through 2.03).
The following function blocks when x=y, but works when
y=x-1.
f x y = do
qSem <- newQSemN 0
forkIO (waitQSemN qSem y)
threadDelay 1000
signalQSemN qSem x
When compiling the following program, the compiler
crashed with a bug. This only happens when compiling
with -O.

I tried compiling a program using -syslib hbc, I
wanted Random.lhs, but I required the standard Time
library aswell. Unfortunately there's an interface
file for hbc called Time.hi, that overrides the
haskell 1.4 Time library. I assume this just requires
renaming of some of the hbc stuff.

Hi,
I've been playing around with mutually recursive modules
and getting nowhere. I tried the following two module
program:
-
\begin{code}
module A where
import B
data A = A Int
findA :: A -> B -> Int
findA (A x) (B y) = x
\end{code}
-
run successfully. Should I be worried about
this?
The program was just a simple Hello World program.
module Main where
main = putStrLn "hello world"

Hi,
I tried installing greencard on Windows NT and had problems. I picked up the basic
binary bundle of ghc and that works ok. I then grabbed greencard. I followed the
install file, running configure, and then trying make boot but got the following error

There seems to be a bug in the Channel module from
ghc-0.29.
If I understand the description in the paper
correctly, dupChan should allow two readers to
both read all the data passed along a channel.
This doesn't work because of the way the getChan
function is written.
It takes the next value fr
