Installing libraries (specifically haskore)

[Bob Harris-2]

Howdy,

I have hugs98 installed and working (on Mac OSX), and I'm now trying
to 'install' haskore (this is my motivation for trying haskell)
http://www.haskell.org/haskore .  I have downloaded haskore but am not
sure how to install it.  The readme file for haskore says

        The best way to use the system with Hugs is to drop the entire Haskore
        directory into Hugs/lib (replacing the one that's there).  All of the files
        except this README file are in the directory Src.

I have no such directory, Hugs/lib.  The readme files is seven years
old so it is apparently talking about how things were done in 2000.
The most likelly candidate (as the equivalent to Hugs/lib) I find is
/opt/local/lib/hugs , or perhaps one of its subdirectories (oldlib,
programs, and packages all seem like plausible choices).  Can anyone
tell me where I should put the Haskore directory?

Further, I don't see any previous version of haskore (if I did, I
guess that would answer that question).  I presume it is no longer
distributed with hugs98.  Am I right, or should I expect to find it
somewhere on my hard drive as part of the hugs98 distribution?

I have another question about haskore, but it is probably not
appropriate for this list so please ignore it unless you are curious.
The haskore readme also says

        1) "Haskore.lhs" will load the entire basic Haskore system.  If your
           Hugs has the proper paths set up, once you drop this directory into
           Hugs/lib, you should be able to just say "import Haskore" and
           everything should work correctly.

I find no file nor directory named "Haskore.lhs" in the distribution.
I find a ""Haskore.hs";  is the paragraph above just a typo?

Thanks for any help,
Bob H

P.S.  Thanks for the help this morning.

The modern equivalent is be to copy the Src directory to
/opt/local/lib/hugs/packages/Haskore.  Unfortunately Haskore also uses
some obsolete stuff: replace fromInt with fromIntegral, and see

        http://www.mail-archive.com/haskell-cafe@.../msg16664.html

for replacements for IOExtensions.  You'll also need

        import Control.Concurrent (bracket)

for the first one.

Thanks!  I'll give it a shot.

I don't find fromInt in the haskore source.  I find fromInteger.
Should I change fromInteger to fromIntegral?  Or is fromIntegral a
typo and haskore has already been updated?

My download of haskore came with the IOExtensions module shown in an
earlier message in that thread, in a separate directory (intended for
ghc users).  I copied it into Haskore/Src.  It imports IOExts which is
not found.  So I then made the changes indicated in msg16664 (plus
removed the offending import).  In this case I got the error
'Undefined variable "bracket"', so I added the import you note above,
and now Iget the error 'Unknown entity "bracket" imported from module
"Control.Concurrent"'.

Any suggestions?

That should be OK.

Sorry: should have been Control.Exception.
