John Lask, The steps you enumerated below successfully built portaudio for me! Thank you! I wonder though, you said to rename the dll to libpa19.dll from portaudio_x86.dll and to change the .cabal entry from "extra-Libraries: portaudio" to "extra-Libraries: pa19". Since my .dll name and .cabal file entry were mismatched, was that what could have been wrong all along? Was the creation of a .a file necessary? I would delete the .a file and retry with libportaudio.dll but I won't push my luck. Now if I could just get Gtk2hs working now, I could be happy *and* productive. :) --- On Sat, 12/5/09, john lask <jvlask@hotmail.com> wrote: From: john lask <jvlask@hotmail.com> Subject: RE: [Haskell-cafe] Low Level Audio - Writing bytes to the sound card?

it's not that c2hs isn't found or something, c2hs doesn't find Base.chs!
Try installing from the unpacked sources (cd portaudio; cabal install) or the old- fashioned way:
cd portaudio-0.0.1
ghc --make Setup
./Setup configure --help (choose your options, prefix, profiling, ...)
./Setup configure $OPTIONS ./Setup build
if all's well,
./Setup haddock ./Setup install
(dies for me with dist/build/Sound/PortAudio/Base.chs.h:1:23: error: portaudio.h: Datei oder Verzeichnisnicht gefunden c2hs: Error during preprocessing custom header file cabal: Error: some packages failed to install: portaudio-0.0.1 failed during the building phase. The exception was: exit: ExitFailure 1 because I don't have portaudio installed) _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
