WinHugs scrollbar doesn't scroll big steps
by Henk-Jan.van.Tuyl 04 Dec '03

04 Dec '03

L.S., The scrollbar of WinHugs only scrolls one line when clicking on the scrollbar, just below the uppermost triangle, or just above the lowermost triangle. This is the case in both Hugs Nov 2002 an Hugs Nov 2003. -- Best regards, Henk-Jan van Tuyl

changing editor
by Ricardo Figueiredo 04 Dec '03

04 Dec '03

Hi guys I am having trouble with latest release of hugs, this because I like to use "editplus" as a default editor for Haskell (I like syntax highlighting). Problem is that when I change editor on hugs, next time I restart it, it gives me a message "unable to load prelude". It seems something to be with the rewriting of editor's path. tried to find it it, but no success. Not a major bug, but it's always useful just to type ":e" to see program. don't know if just me, sine no talking to anyone. Just trying to help Ricardo Figueiredo

Problems compiling hugs-2003.11 with threading and hopengl support
by james.noble＠worcester.oxford.ox.ac.uk 03 Dec '03

03 Dec '03

(Note: "reply"ing to this email may cause a bounce... since my mail client may still be misconfigured. The correct email address is at bottom of this mail) I won't repeat a lot of typing which I have already done, here's a handy link which explains the issue: http://bugs.gentoo.org/show_bug.cgi?id=34858 Here's some random extra information (not necessarily on the page in the above link): -- uname -a: Linux theferret 2.6.0-test9-gentoo #2 Sun Nov 9 15:57:51 GMT 2003 i686 AMD Athlon(tm) XP 3200+ AuthenticAMD GNU/Linux -- gcc version: gcc (GCC) 3.3.2 20031022 (Gentoo Linux 3.3.2-r3, propolice) -- glibc version: 2.3.2-r9 -- XFree86 version: XFree86 Version 4.3.0 Release Date: 27 February 2003 X Protocol Version 11, Revision 0, Release 6.6 -- Compiled from: hugs98-Nov2003.tar.gz (source) This problem did not appear in the Nov2002 sources, but then I don't know if those sources had threading and hopengl support. I have tried compiling using default xfree opengl headers and interface, and that works fine. Maybe the fact is that the nvidia drivers just don't support threading? Thanks.. -- James Noble <james.noble(a)worc.ox.ac.uk>

Fran1.16 and Hugs98-Nov2003
by Antony Courtney 01 Dec '03

Hi, Has anyone succesfully used Fran1.16 and Hugs98-Nov2003? I was using an older Hugs (Nov. 2002) with Fran earlier today, and that worked fine. After upgrading, however, I appear to be hitting some issues with hierarchical name spaces: antony@goliath ~ $ hugs -98 Fran __ __ __ __ ____ ___ _________________________________________ || || || || || || ||__ Hugs 98: Based on the Haskell 98 standard ||___|| ||__|| ||__|| __|| Copyright (c) 1994-2003 ||---|| ___|| World Wide Web: http://haskell.org/hugs || || Report bugs to: hugs-bugs(a)haskell.org || || Version: Nov 2003 _________________________________________ Hugs mode: Restart with command line option +98 for Haskell 98 mode ERROR "C:\\frp\\Fran\Src\FranLoader.hs" - Can't find imported module "InputMonitor" Prelude> ...examining the body of Fran.hs, it appears to be using a previous Hugs feature for loading a module from a sub-directory which clashes syntactically with hierarchical module support: $ cat Fran.hs ---------------------------------------------------------------- -- Redirection module so that you don't have to put -- "./src" on your Path. -- -- Suitable for use with Hugs 98 on Win32. ---------------------------------------------------------------- module Fran(module Src.FranLoader) where import Src.FranLoader ---------------------------------------------------------------- antony@goliath /cygdrive/c/frp/Fran $ ...but, unfortunately, attempting to load FranLoader directly doesn't work either: antony@goliath /cygdrive/c/frp/Fran/src $ hugs -98 FranLoader __ __ __ __ ____ ___ _________________________________________ || || || || || || ||__ Hugs 98: Based on the Haskell 98 standard ||___|| ||__|| ||__|| __|| Copyright (c) 1994-2003 ||---|| ___|| World Wide Web: http://haskell.org/hugs || || Report bugs to: hugs-bugs(a)haskell.org || || Version: Nov 2003 _________________________________________ Hugs mode: Restart with command line option +98 for Haskell 98 mode ERROR ".\BaseTypes.hs" - Unknown entity "int32ToInt" imported from module "Int" Concurrent> Any help or suggestions would be appreciated.

Hugs, graphics, and SOE
by Paul Hudak 01 Dec '03

01 Dec '03

The Hugs download page used to have links for downloading SOEGraphics and/or HGL, but now they're gone. In fact there was a self-installing download that automatically installed everything needed to run SOE code under Windows, but it is also gone. I believe that there are also incompatibilities between the latest Hugs and the graphics libs. Thus I'm starting to get complaints from users who are trying to use SOE. We need to (a) sort out the incompatibilities, and (b) figure out where to point SOE users to mimimize their downloading headaches. Please advise. -Paul

ERROR - Garbage collection fails to reclaim sufficient space
by Henk-Jan.van.Tuyl 01 Dec '03

01 Dec '03

L.S., When reading a lot of files, Hugs gives the message: ERROR - Garbage collection fails to reclaim sufficient space I had this problem before with Hugs Version Nov 2002 after 40 files, now with Hugs Version Nov 2003, it happens after 60 or 61 files; see the attached program. If you want sample data files, just ask me. -- Best regards, Henk-Jan van Tuyl

Winhugs: Wrong options settings / cannot open Prelude
by Henk-Jan.van.Tuyl 30 Nov '03

30 Nov '03

Hello all, I'm experiencing two problems at about the same time, I do not know if they are related: After setting an option for winhugs, using the GUI, Winhugs refused to start, displaying an error message about expecting another double quote. I solved this by changing the Options in the registry: HKEY_CURRENT_USER\Software\Haskell\Hugs\WinhugsNov2003\Options had the following value: -s -t -g -G -l -. +q -Q -w -k -o -O +u -I -T +A +R -H +98 -h250000 -p"%s> " -r"$$" -P".:{Hugs}/libraries:{Hugs}/oldlib:{Hugs}/libraries/win32" -S".hs;.lhs" -E"C:\\WINDOWS\\notepad.exe" -c40 -F"" " I removed the double quote at the end. The error message about the double quote is now replaced with the message: ERROR - Unable to open file "C:\PROGRAM FILES\HUGS98/libraries\Hugs\Prelude.hs I am running: Hugs '98 Nov 2003 on Windows 98 -- Best regards, Henk-Jan van Tuyl

Bug in Windows version
by Jinu Lee 26 Nov '03

26 Nov '03

Hello, After I install the new version of Hugs98 on Windows, if I run it, it says that it cannot find MSVCR70.dll and exits. I guess that the installer doesn't copy MSVCR70.dll in the Windows system directory.
