Re: Installation Problem GHC 6-6
Hello, Can you tell us exactly which package you have attempted to install? That would be very useful, thanks. Also, if you could make the exact sequence of commands used and the output somehow available, that would also help a lot to figure out what has happened. (A quick shot at a possible solution would be to say sudo make install rather than just make install to install as root. Unfortunately, the error messages you quote don't really indicate that lack of permissions is the problem, so I am not really sure that this suggestion would work.)

Comment:
I can't reproduce this with GHC 6.6.1 on Debian/amd64, having compiled hxt
from http://www.fh-wedel.de/~si/HXmlToolbox/HXT-7.2.tar.gz with Cabal.
Does anyone have a way to reproduce it please?

Re: Bug involving graphics under OS X
On Tue, 2007-07-17 at 15:49 -0400, Scot Drysdale wrote: I am preparing to teach a course this fall from Paul Hudak's _The Haskell School of Expression_. In running Picture.lhs, one of the example programs form the book, I am getting strange graphics behavior. I load the program using ghci and type main. The graphics window appears, but only one or two of the four shapes is drawn. But if I resize the window (or let the screen or computer sleep and awaken, or cover the window and then uncover it), all four shapes appear. When clicking on a shape to bring it to the front, only the last drawn shape appears on the screen. Again, resizing the window reveals all four shapes drawn correctly. The fours files needed to produce this behavior are enclosed, and a full session (using the -v flag on ghci) is shown below. I modified the files to use the library Graphics.SOE instead of SOEGraphics, which was needed to run under ghc (as opposed to HUGS). The HGL package which Graphics.SOE is based on is unmaintained and fairly buggy on several platforms, especially in GHCi since it uses threads in a way that is not especially nice (or so I have heard) and GHCi uses the -threaded runtime system which uses multiple real OS threads so it can expose dodgy uses of threads. It may work better in Hugs since its implementation of threads is totally different to that of GHCs and HGL was originally implemented and tested with Hugs. Alternatively you could use the implementation of the SOE api that comes with Gtk2Hs. It's a totally different implementation but has the same API and tries to preserve the same behaviour (though it's not 100% the same, there are reports of bugs in the region code). In the latest version of Gtk2Hs it's possible to use Graphics.SOE.Gtk from GHCi (ie it works with the -threaded rts) The latest version is here: http://haskell.org/gtk2hs/gtk2hs-0.9.11.3.tar.gz That's the first release candidate for 0.9.12 which should be announced and released in the next few days. There's also a windows installer (swap .tar.gz for .exe in the above url). It should work on OSX (but I can't test it personally so have to rely on people to report problems). In case you're interested, I've been using Gtk2Hs (though not the SOE api) for a programming practical for a first year FP course at Oxford for the past couple of years: http://haskell.org/gtk2hs/archives/2005/11/01/university-courses-using-gtk2hs-for-teaching/ Am FP course at Jyväskylä in Finland has used the SOE api. In fact that is where the new implementation stems from. Duncan ___ Glasgow-haskell-bugs mailing list Glasgow-haskell-bugs@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-bugs

Noticed here:
http://calculist.blogspot.com/2007/07/cute-idiom-from-haskell.html
The following is accepted by GHC:
{{{
main = do
getChar - c
print c
}}}
Yielding the same program as if we'd written;
{{{
main = do
c - getChar
print c
}}}
The above blogger uses this to ingeniously embed:
{{{
gamma |- e - v
}}}
in Haskell, but surely this is either a lexer bug, or an interesting
syntactic feature that shouldn't be enabled by default?
