You need to wrap up the use of sockets in a "withSocketsDo", as in: > server port = withSocketsDo $ > do socket <- listenOn port > -- etc I seem to recall the documentation says you always need to use that, so I don't know why it works without on Linux :-) Hope this helps, Matthew -----Original Message----- From: glasgow-haskell-users-admin(a)haskell.org [mailto:glasgow-haskell-users-admin@haskell.org]On Behalf Of Steinitz, Dominic J Sent: Friday, February 23, 2001 11:10 AM To: glasgow-haskell-users Subject: Sockets on Windows I am was trying out sockets.

Problems when mounting c: to /
by andreas.marth＠daimlerchrysler.com 24 Feb '01

24 Feb '01

Hallo everybody! When installing ghc-4.08.2 (onWinNT) as described in the installation instructions under c:, I couldn't get ghc to run. It invoked the C-preprozessor and stoped after cleaning. When I unmount c:, it works fine. (If I install cygwin and dont mount c: to / it works fine too.) But now //c/ is the normal win-root. That's not a problem for me, but how about ghc? Does it depend in any way on c: mounted to /? If not why do you want this mount (in the installation instructions section 2.2.2.1)? Thanks, Andreas PS: Thanks Reuben for the new install shield and a very big thanks to all of you who have their parts in getting the profiling to run under WinNT

Why should it behave differently? If you want 'make install' to be idempotent (which I'm not sure is desirable anyway), then you will indeed have to ghc --delete-package first, but then I hope you're going to print a big warning and wait for the user to press any key first :) Cheers, Simon

There is no real safety, because the package > is explicitly deleted anyway. I don't think I agree. Installation of an external package shouldn't be doing --delete-package first: that should be left to the user (or rpm -e, or whatever). If you want to install a new package that replaces an existing one, you have to remove the existing one first. Cheers, Simon

> administrator@DEFAULT /cygdrive/d/dom/home/socketTest > $ ./server1 8000 > > Fail: does not exist > Action: getProtocolByName > Reason: no such protocol entry Just from looking at the manpage for getprotobyname, I surmise that the problem is that you don't have an /etc/protocols file (or equivalent) under Windows. I'm not sure what's supposed to happen (or for that matter, what's supposed to work). Look in hslibs/net/BSD.lhs; I couldn't work out what was going on in a minute; perhaps someone else knows. The other thing I couldn't work out was where getProtocolByName was being called in the first place, but presumably it's to find the protocol number of tcp. -- http://sc3d.org/rrt/ | Slow Pedestrian Crossing

--add-package
by qrczak＠knm.org.pl 23 Feb '01

23 Feb '01

In practice installation script of an external package does --del-package before --add-package, because if it was installed before, --add-package would cause an error. Wouldn't be reasonable then to let --add-package overwrite any existing package of that name? There is no real safety, because the package is explicitly deleted anyway. -- __("< Marcin Kowalczyk * qrczak(a)knm.org.pl http://qrczak.ids.net.pl/ \__/ ^^ SYGNATURA ZASTÊPCZA QRCZAK

New GHC InstallShield: mingwin problem fixed
by Reuben Thomas 21 Feb '01

21 Feb '01

I have just uploaded a new GHC InstallShield. It fixes the recent problem with needing a particular version of the mingw package. Unfortunately the situation here is still unstable (roll on Cygwin 1.2), so it may break again, but it seems to work for now. -- http://sc3d.org/rrt/ | certain, a. insufficiently analysed

Installation of mingw-20001111-1.tar.gz
by Byron Hale 21 Feb '01

21 Feb '01

Hi, I'm trying to install mingw-20001111-1.tar.gz for ghc4.08.2. The instructions on Win2K. The Web instructions seem a bit cavalier, but perhaps it is just my ignorance. ..."directory called mingw, place that in a directory called latest, then run the Cygwin installer "... Are these intended to be sub directories of Cygwin's "bin" directory, or what? Is the Cygwin "installer" "bin/install.exe?" If so, install with what options?
