Hi Haskellers, It seems that profiling and threading are not supported at the same time in GHC6.6. At least, it objects to using both the flags at the same time, and there's a Trac entry for that issue. So I just wanted to be sure that I really need threading. I'm passing text through some filters written in perl, just ordinary command line programs. I do it like this:
do (hin, hout, herr, ph) <- runInteractiveProcess cmd args Nothing Nothing forkIO $ hPutStr hin content >> hClose hin out <- hGetContents hout return (ph, out)
which seems to require threading. If I compile without, it will hang indefinitely, I presume deadlocked. Is there a way this can be done without threading? But it's not a great issue for me if I can't do profiling in this case. I just wanted to try out the feature, and it seemed worthwhile checking I was doing this right. Cheers, Dougal.
