Hi again.
Further to my earlier report today:
1. Further CVS source HDirect Makefile dependencies needed as follows (not
necessarily exhaustive, see 3 below):
Com.o : WideString.o ComPrim.o ComException.o
Automation.o : SafeArray.o AutoPrim.o
SafeArray.o : StdTypes.o
2. While compiling the ihc generated file AutoPrim.hs, errors like the
following arise:
==fptools== make all - --unix -r;

Compilation had errors

PSEUDOFIX: Naively (I am still a Haskell learner and don't understand the
consequences) added arguments to the type declarations as follows:
type IDispatch a = IUnknown a
dispatchInvoke :: IDispatch (a)
This is a HDirect bug?

3. In automation.lhs:
Automation.lhs:7:
Type constructor or class not in scope: `IDispatch_'
Automation.lhs:351:
Type constructor or class not in scope: `IDispatch_'

The Sender field should be ignored (as per RFC 822) by mail software if there's a From field. The first From field is not legal as it is not delimited by a ':' I'd say the Pine setup is wrong. --Sigbjorn
RE: (no subject)
Hi,
I think you're OK, but the contents of what
was installed may have confused you. When
using the InstallShield version, you only need
to run the installer - it takes care of the
noodling that "./configure --yadda; make {install,in-place}"
performs.
Please ignore the presence of the configure script
(and Makefile) in the directory tree that the IS
installer produces have a go with the installed GHC.

Dear Sir ! Sorry to bother you. I'm using Windows 98 already installed GHC as your instructions. However, I can not find ghc.exe or some thing like that to compile my program. In the directory "bin", there is only 1 executable file hp2ps.exe ? Could you please to help me (as soon as possible) ? Thank you very much !

The program below is compiled on an i386 under Linux, and invoked: test +RTS -K10m braga.tex (a file of about 20K) this gives a segmentation fault test +RTS -K10m -H20m braga.tex works fine. It also works fine when compiled under Solaris on a Sun Sparc. It would appear, therefore, that there is a problem with garbage collection under linux. Is this a Known Problem with a Known Work-around? I am lecturing at next week's Summer School on Advanced Functional Programming, and had hoped to produce a binary with ghc for students to play with. All was developed under Solaris, and I naively assumed it would work under Linux without any ado... A swift response would be much appreciated! -- module Main (main) where import List main = do putStr "test\n" putStr "type input file name: " filename - getLine input - readFile filename putStr (sort input)
Re: (no subject)
Hi, what version of ghc did you compile your program with? Based on your stack size setting, I'm guessing ghc-2.10 :-) Since then, List.sort has been speeded up quite a bit (i.e., we're not using the sample implementation in the Prelude any longer), and I'm unable to reproduce your problem with ghc-3.02 (or ghc-3.03). If you don't want to upgrade ghc right now, I can compile up your code on a local linux box, if you like. --Sigbjorn Oege de Moor writes: The program below is compiled on an i386 under Linux, and invoked: test +RTS -K10m braga.tex (a file of about 20K) this gives a segmentation fault test +RTS -K10m -H20m braga.tex works fine.

Hello, I'm beginning to program in Haskell and I'm using GHC 2.02. Do you would be able to detect errors in the code following and, eventually, write me the code corrected ? main = do fileTran - openFile "dfatran.dat" ReadWriteMode t - hGetContents fileTran putStr "String to recognize :" st - getLine tr - updatetran (transflist (words t)) (grammar 1) (epsClosure "S" (grammar 1) ((length (lines (grammar 1))) - 1)) st putStr (msgstring tr) fileTran - openFile "dfatran.dat" WriteMode hPutStr fileTran (flattran tr) putStr "End program\n" Thank you in advance, Francesco Arrigo
