0.7 build failure about tidal HOT 11 CLOSED

This is due to PortMidi-0.1.6.0 being released

from tidal.

Thanks @bergmark, from the changelog:

Sun Apr 3 00:46:02 PDT 2016 [email protected] * PMEvent uses CLong as message type to better handle SysEx. - This is a breaking change. Use encodeMsg or decodeMsg to work with PMMsg.

from tidal.

finally, I've been waiting for this change for a very long time.

however, to avoid breakage in the future, I'll try to fix it against master and also lock version to 1.6.0 in tidal.cabal

edit: @bergmark oh I see you already added the upper bound

from tidal.

I made a branch 0.7.1 for this about to commit a quick fix.. are we duplicating on work?

from tidal.

@yaxu no, I just checked, the change I've been waiting for was already introduced in 1.4. I haven't done any work on this you are free to merge

from tidal.

Righto @lennart can you please check 0.7.1 branch for sanity before I merge and send to hackage please

from tidal.

#102

from tidal.

this is not related to the change itself but we have to be aware that this will again lead to breakage for all users on OS X, mostly because portmidi is not compiled correctly by cabal. I guess these options have to be added on the PortMIDI side (PortMidi.cabal), we need to instruct people on OS X to do:

cabal install portmidi --ghc-options="-optl-Wl,-framework,CoreMIDI,-framework,CoreAudio" --reinstall --jobs=1 --force-reinstalls

as seen in the install guide for OS X under Haskell

from tidal.

everything seems fine with tidal 0.7.1, portmidi 1.6 on osx 10.11.4 ghc 7.10.2

from tidal.

Thanks, uploaded to hackage now. Shall we split portmidi and serial into separate packages as they cause problems? They caused issues elsewhere too commercialhaskell/stackage#1299 commercialhaskell/stackage#1297

from tidal.

yes. having a generic backend in core is good. dropping dependencies on this repo seems like a good plan.

I guess eventually haskell midi and serial implementation may only be necessary if running supercollider/superdirt is not an option. I guess SuperDirt should be easily extendable to allow midi and also serial controls analog to the current way to write custom synthdefs.

This might ease the process of getting midi (and also serial) to work for newcomers, as supercollider is easily installable on all major platforms (?!) and comes with serial and midi support out-of-the-box (not sure about the quality of the serial port interface though).
