Thank you!<br><br>I wonder though, you said to rename the dll to libpa19.dll from portaudio_x86.dll<br>and to change the .cabal entry from "extra-Libraries: portaudio" to "extra-Libraries: pa19".<br>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?<br>I would delete the .a file and retry with libportaudio.dll but I won't push my luck.<br><br>Now if I could just get Gtk2hs working now, I could be happy *and* productive. :)<br><br>--- On <b>Sat, 12/5/09, john lask <i><jvlask@hotmail.com></i></b> wrote:<br><blockquote style="border-left: 2px solid rgb(16, 16, 255); margin-left: 5px; padding-left: 5px;"><br>From: john lask <jvlask@hotmail.com><br>Subject: RE: [Haskell-cafe]
