[haskell-art] port midi

[Miguel Negrao]

Hi all,

I was trying to get MIDI working with Haskell. I have portmidi installed via homebrew on an osx 10.7 machine with ghc 7.4.2. trying to use the portmidi package I get an error:

Prelude> import Sound.PortMidi
Prelude Sound.PortMidi> initialize
Loading package PortMidi-0.1.3 ... linking ... done.
Segmentation fault: 11

Any hints on how to proceed ?

best,
Miguel

Hi,

I cannot help with portmidi, however, if you don't need Linux
compatibility, the hmidi package (http://hackage.haskell.org/package/hmidi/)
works on both OSX and Windows (and does not have any external
dependencies). There are some simple examples included in the package.
Don't forget to use the --threaded flag when building.

JACK and the Haskell jack package are another option.
