I dunno. 'make distclean' leaves the configure scripts in place, 'make maintainer-clean' is supposed to get you back to a pristine tree as it would be if it were just checked out from CVS.

You use the usual 'ar' tool for making a .a library, something like: $ ar cru libfoo.a a.o b.o c.o To make this into a package, see the section on packages in the user's guide: http://www.haskell.org/ghc/docs/5.00/set/packages.html Cheers, Simon

New InstallShield: Free At Last
by Reuben Thomas 23 Apr '01

23 Apr '01

I've uploaded a new InstallShield for GHC 4.08.2 for Windows which includes *all* the programs required to use and even rebuild GHC from source [GHC developers should note that it doesn't include everything needed to build from CVS; see the most recent 5.00 docs in CVS for details]. This means that there's no longer any need to install Cygwin. Since GHC needs bash to work, and building it requires mv, rm and cp, plus many other basic utilities, you get a reasonably nice minimal command-line environment anyway; I've added ls to the mix for extra comfort. Although the InstallShield is now 20M, overall there's far less to download, and now GHC should break far less often. Another implication of this development is that the Windows version of 5.00 should now happen sooner rather than later. One caveat: the installation instructions on haskell.org are now somewhat out of date. I'll try to correct that soonish. -- http://sc3d.org/rrt/ | Si hoc legere scis nimium eruditionis habes.

no problem with .sgml

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
