Windows Support

[ssfrr]

Pretty much the only thing that should need to be fixed to work in windows is the synchronization between the Julia task and the C PortAudio callback. Currently we're using a POSIX semaphore and a file descriptor. I'm not sure what the best windows equivalents are.

looks like you've removed the requirement for this?

it also would be nice to hook up BinDeps support, esp. since both portaudio and libsndfile are already available via WinRPM

[ssfrr]

which change are you referring to? I've got the issue up but windows support hasn't been a priority.

I was avoiding Windows support because of the custom C shim and multithreading gymnastics I was doing before, but now that those are gone it should be pretty easy.

I just added the WinRPM lines to REQUIRE and build.jl, though I had to guess at the package names. Is there a list of WinRPM packages online somewhere?

[ssfrr]

Via email Aitor Ortiz de Latierro Olivella informed me that the packages are:

• "libportaudio2" (libportaudio2 (mingw64) - Portable Real-Time Audio Library)
• "libsndfile1" (libsndfile1 (mingw64) - A Library to Handle Various Audio File Formats)

I changed the names in the package script, hopefully that helps. If anyone can test on Windows please let me know.

Now this message appears just after the "INFO: Complete" of the libportaudio2 installation.

[ssfrr]

Hmm, what happens if you try to use AudioIO even though the build throws the error? Are you able to play sound?

[aiorla]

With just "using AudioIO":

I've manually installed "libsndfile1" and the error in the "using AudioIO" doesn't appear. (it is not installed in the build process because of the error)
Now I'm going to try play, I will update this comment with the results shortly. (10 min)

UPDATE: Every method like play, ArrayPlayer, SinOsc, read "is not defined" :(
UPDATE2: On the other hand methods like "AudioIO.open(wavFile)" work.

Hi, sorry, I didn't see these updates because apparently GitHub doesn't sent notifications on updates, only new comments.

I'll see if I can get AudioIO up and running on a Windows machine myself so I can better debug. I'll comment back when I have some more info. Probably next week.

Still getting the same error on my Windows 10 machine with Julia 0.3.11 when building AudioIO:

===============================[ ERROR: AudioIO ]===============================

[rennis250]

I've also been finding this error. Any guesses on what one should do?

[ssfrr]

Are you running the release version or master? If you're not running the latest master try checking it out with Pkg.checkout("AudioIO"). I fixed the package names to what hopefully are the correct ones, but that hasn't made it into a release yet because I haven't tested it.

[wherrera10]

It seems that the RPM provider of libportaudio2 does not provide what AudioIO wants? Or is the build script in error somehow?

According to the RPM page at http://rpmfind.net//linux/RPM/opensuse/12.1/i586/portaudio-19-273.1.3.i586.html the RPM provides:

portaudio
libportaudio.so.2
portaudio(x86-32)

Is this what AudioIO needs? Or should a different RPM be used?

[wherrera10]

Ah, here it is: for Windows to build, there have to be aliases. In build.jl the lines need to change to:

libportaudio = library_dependency("libportaudio", aliases=["libportaudio-2"])
libsndfile = library_dependency("libsndfile", aliases=["libsndfile-1"])

[rennis250]

Great! Thanks for that. Will test soon.

[ssfrr]

Thanks for the windows help, @wherrera10. If this change is confirmed working than I'll merge in #50. (I don't think it should break anything on linux or osx and seems a strict improvement on windows).

Thanks!

Also, so you know, AudioIO.jl is going to be deprecated relatively soon and the functionality broken out into separate packages for audio file I/O, device I/O, and building DSP graphs. (see #48 with some more info) Changes like this will definitely make it into the new packages though, so it's definitely still helpful.
