I just found out that I can circumvent the problem by adding a line import Char to my loaded file. regards, -john

RE: [Hugs-bugs] problems building on Solaris
by herington, dean 01 Jun '04

01 Jun '04

After a hiatus, I'm back trying to get Hugs built for Solaris. I never had a reply to the message attached below. Can anyone help? One newly noticed bit of puzzlement: configure yields: /* C compiler invocation use to build a dynamically loadable library. * Typical value: "gcc -shared" * Must evaluate to a literal C string. */ #define MKDLL_CMD "gcc -g -r" but I can't find any mention of "-r" for gcc on Sparc.

I think you're using an old version of Hugs/Prelude.hs. You need to copy the new versions of files in libraries/Hugs from the source bundle to wherever Hugs is looking for them (-q will tell you where).

[Hugs-bugs] broken links
by Paul Hudak 27 May '04

27 May '04

Dear Hugs maintainers -- There are several links that are broken on the Nov2002 download page at http://cvs.haskell.org/Hugs/pages/downloading-Nov2002.htm. These are important to me because the current release of Hugs is compatible with the graphics library used in my book (SOE), so for now I have been pointing people to the Nov2002 release. Two of the links I know how to fix: cvs.haskell.org/Hugs/downloads/GraphicsLib.msi should be cvs.haskell.org/Hugs/downloads/Nov2002/GraphicsLib.msi and cvs.haskell.org/Hugs/downloads/SOE.msi should be cvs.haskell.org/Hugs/downloads/Nov2002/SOE.msi But several of the others (involving sources, Unix, and Linux) I don't know how to fix. I would appreciate it if you could update these links, expecially the two above. Thanks, -Paul Hudak -- Professor Paul Hudak Chair, Dept of Computer Science Office: (203) 432-1235 Yale University FAX: (203) 432-0593 P.O.

[Hugs-bugs] Re: Setting Search Path doesn't persist in WinHugs
by Greg Ballinger 04 May '04

04 May '04

AHA, I found the problem. When starting the WinHugs.exe file directly in C:\Program Files\Hugs98 it does use the persisted search path. However when starting it via the shortcuts installed in the Windows Start Menu system it does not. Evidently the shortcut in the menu uses an empty -P option when starting WinHugs. Sigbjorn Finne told me "I'll fix this in the next release, but creating your own shortcuts sounds like the simplest way out." For those unfamiliar with creating Windows shortcuts, an easy way to do this is: 1) navigate to the WinHugs.exe file, 2) right-click, 3) select Send to desktop (Create shortcut). 4) drag or copy the shortcut to wherever you want it. If you wish to set WinHugs command line options in your shortcut 1) right-click on the shortcut after you have created it 2) select Properties 3) Type your selected command line options at the end of target line Example: "C:\Program Files\Hugs98\winhugs.exe" +t will cause WinHugs to display the result and type of each expression entered at the Hugs prompt: Hope this is helpful and not too elementary. --Greg Ballinger
