The documentation should be supplied in .html and .ps files, at least in the .tar.bz2 binary build I did, and, I presume in the RedHat 6.2/7.0 RPMs. Are you saying this is not the case?

how to implement timeouts for IO operations?
by Johannes Waldmann 19 Apr '01

19 Apr '01

what is the Right Way to impose a timeout condition on IO actions? the GHC manual says ( http://www.haskell.org/ghc/docs/5.00/set/select.html ) "use threadDelay and asynchronous exceptions". When I do this: timed :: Int -> IO a -> IO a timed d action = do let timer = do threadDelay d throw $ AssertionFailed "timer expired" t <- forkIO timer x <- action killThread t return x it seems to work, but how do I turn off the "Fail: thread killed" messages? -- -- Johannes Waldmann ---- http://www.informatik.uni-leipzig.de/~joe/ -- -- joe(a)informatik.uni-leipzig.de -- phone/fax (+49) 341 9732 204/252 --

by andreas.siglreithmayr＠sdm-research.de 19 Apr '01

I run ghc under cygwin WinNT. If I compile a simple HelloWorld program as described in the instalation descripton, I get the following error: $ ghc -o main main.hs gcc: D:/Unix/ghc/lib/Main.dll_o: No such file or directory gcc: D:/Unix/ghc/lib/PrelMain.dll_o: No such file or directory Do you know whats wrong? Or where can I get the files? -- Andreas Siglreithmayr mailto:Andreas.Siglreithmayr@sdm-research.de sd&m Research GmbH http://www.sdm.de Thomas-Dehler-Str. 18 , D-81737 Muenchen, Germany Tel +49 89 63812-917 Fax -150

compiling ghc 5.0 with cygwin
by John.Velman＠HSC.com 17 Apr '01

17 Apr '01

I am using Cygwin on an NT4SP5. I have a recent (i.e., up to date) installation of Cygwin (1.1.8-2). I installed ghc 4.08.2, and it seems to work. At least the simple "hello" works, and happy-1.9 seemed to compile and install with no problems. When I tried to compile ghc-5.00, my "make" run ends with the following error ______ ....tail of make output: ------------------------------------------------------------------------ ==fptools== make boot - --unix - --no-print-directory -r; in /home/newarchives/haskell/ghc5/ghc-5.00/ghc/utils/hsc2hs ------------------------------------------------------------------------ Creating Config.hs ... done. make INSTALLING=0 BIN_DIST=0 - --unix - --no-print-directory -r all /usr/local/bin/ghc -package util -O -c Config.hs -o Config.o -osuf o /usr/local/bin/ghc -package util -O -c KludgedSystem.hs -o KludgedSystem.o -o suf o /usr/local/bin/ghc -package util -O -c Main.hs -o Main.o -osuf o /usr/local/bin/ghc -o hsc2hs-bin -package util -O Config.o KludgedSystem.o Main.o V:/usr/local/lib/ghc/ghc-4.08.2/lib/libHSstd.a(Time.o)(.text+0x1c42c):ghc1360.c: undefined reference to `_imp___timezone_dll' collect2: ld returned 1 exit status make[4]: *** [hsc2hs-bin] Error 1 make[3]: *** [all] Error 2 make[2]: *** [boot] Error 1 make[1]: *** [boot] Error 1 make[1]: Leaving directory `/home/newarchives/haskell/ghc5/ghc-5.00/ghc' make: *** [all] Error 1 _______ Has anyone seen this before -- is it a cygwin bug or a ghc bug? Well, you know all the questions. I hope someone knows the answers! John Velman john.velman(a)hsc.com

Haskell2Xml - Some questions
by Lescher Christian 17 Apr '01

17 Apr '01

Hi Malcom, While doing my first steps with Haskell2Xml, some more questions arose: - Is there any support for floating point numbers (e.g. Double)? - Is it possible to read/write XML data directly from/to strings (instead of using readXml and writeXml)? This is especially interesting when exposing Haskell functions within a Win DLL (and that's what I want to do after all). - May I tell Haskell2Xml somehow to leave out the DTD output and write only the "data contents"?

solved! Fw: win32 4.08.2 install question
by David Bakin 15 Apr '01

15 Apr '01

Found the problem in Sigbjørn Finne's FAQ at http://www.dcs.gla.ac.uk/~sof/ghc-win32-faq.html: I had no /bin, only a /usr/bin. I've gotten hello world to compile so I'm off and running. If 5.00 wasn't switching to a Haskell driver I'd suggest updating the GHC installation on windows page with this FAQ. -- Dave $ mount Device Directory Type Flags c:\Cygwin\bin /bin user textmode c:\Cygwin\etc /etc user textmode c:\Cygwin\lib /usr/lib user textmode c: / user textmode ----- Original Message ----- From: David Bakin To: glasgow-haskell-users(a)haskell.org Sent: Sunday, April 15, 2001 12:47 AM Subject: win32 4.08.2 install question While waiting for 5.00 for win32 I thought I'd get started with 4.08.2 - downloaded it today and installed it and the latest cygwin as per instructions. However: When following the "test the fruits of your labour" I invoke "ghc -o main main.hs" and get back a bash prompt and that's all. No files created, e.g., no main. Same for "ghc -c main.hs". Something trivial must be wrong with my setup. I've copied the ghc/bin/perl to cygwin/bin. No spaces in any directories (ghc is installed at c:\ghc). My mounted dirs look like this: C:\Cygwin\bin>mount Device Directory Type Flags c:\Cygwin\bin /usr/bin user textmode c:\Cygwin\etc /etc user textmode c:\Cygwin\lib /usr/lib user textmode c: / user textmode Anybody have an idea what's going on? I can't wait to get 5.00 and its integral driver! -- Dave
