-i naked flag
by Alex Jacobson 24 Dec '07

The current docs use -i without any arguments to reset the path back to []. That is an interesting feature but it is much less useful than being able to use shell based tab completion when entering command line options. I suggest that the -i reset feature be removed in favor of e.g. --clear-search-path -Alex-

If you want I can send you the portfile to try, I can't guarantee it but it seems to work most of the time. If the build fails, just "sudo port clean" and try again. > How can I build the libraries in the current leopard release? I don't understand your question.

I have had successful builds on these platforms and the Portfile is updated. However, the 6.8 branch seems to have introduced a bug in file locking (#1992 in the trac) that causes the build to fail once out of every four or five times. This is not acceptable for a production release, so this has to be tracked down before GHC from macports is updated. Sorry for the delay, Greg

My experience with the mac stuff is that you are just better off building everything yourself. It runs in the background while you go eat dinner and then you are done. -Alex- Hugo Pacheco wrote: > The binaries do work in Leopard, but it misses all library files, such > as System.IO. > How can I build them form the sources?

Hello, First of all: Welcome to the club. I hope you will find it enjoyable. And then to your questions: I have never tried to bootstrap GHC from C, so I am not really able to help with your specific problem. However, if you just want a running GHC, the binary distributions should provide an easy path. I have installed several binary GHC packages on various PPC Mac OS X machines and, generally, they work. You should, however, be aware of several, relatively recent, problems that have popped up that seem connected with GHC 6.8.1 and Leopard. See for example http://hackage.haskell.org/trac/ghc/ticket/1958. For example, I have a GHC 6.6.1 running on both 10.4 (Tiger) and 10.5 (Leopard) that I installed from http://haskell.org/ghc/dist/6.6.1/ghc-6.6.1-powerpc-apple-darwin.tar.bz2 (see http://haskell.org/ghc/download_ghc_661.html#macosxppc) Once you have a running binary GHC, you can start building (newer) GHC's from source distributions or darcs repositories. Feel free to write back, if this is not the right answer to your questions.

More spam problems on trac
by Tim Chevalier 20 Dec '07

20 Dec '07

It seems the new thing for spammers to do is to add spam text wrapped in the <p style=display:none> tag. For example, http://hackage.haskell.org/trac/ghc/wiki/WikiStart?action=diff&version=106 I don't know if anyone else has noticed this. Maybe it's time to require captchas for account creation or something?

How do you get the process id out of the ProcessHandle in Win XP?
by John Vogel 20 Dec '07

20 Dec '07

Here is what I have tried: module Main where import System.Process -- using runInteractiveProcess import System.Posix.Types import System.Process.Internals import Control.Concurrent.MVar main = do (input,output,err,ph) <- runInteractiveProcess calc.exe" ([]) Nothing Nothing p <- Main.getPID ph putStrLn $ show p --- The output getPID :: ProcessHandle -> IO CPid getPID (ProcessHandle p) = do (OpenHandle pp) <- takeMVar p return (toPID pp) toPID :: PHANDLE -> CPid toPID ph = toEnum $ fromEnum ph --------------------------------------------------------------------------------------------------------------------------- But the CPid always returns some const value (like 1904 in cygwin; 1916 in cmd.exe) I think, I saw that CPid was a newtype of Ptr () So, currently I need to get the process id from CPid or something else. All help is appreciated. John

C Preprocessor

Is it already a known problem that the preprocessor cannot cope with the whole set of possible string declarations? $ cat long1.hs {-# OPTIONS -cpp #-} s = "abc\ \defg" main = putStrLn s $ ghc long1.hs long1.hs:3:14: lexical error in string/character literal at character 'e' $ cat long2.hs s = "abc\ \defg" main = putStrLn s $ ghc long2.hs $ a.out abcdefg
