Problems when doing multi-threading

[sletz]

I'm trying to use PortAudio.jl in an application where the running audio code control parameters have to be updated in real-time with a GTK based GUI.

The PA template code is here: https://github.com/grame-cncm/faust/blob/master-dev/architecture/julia/audio/portaudio.jl

The GTK Controller code is here: https://github.com/grame-cncm/faust/blob/master-dev/architecture/julia/gui/GTKUI.jl

I need to start the GTKUI code, make it do not block the calling thread, and have the PortAudio audio rendering code start later on.

I tris using Threads.@spawn without success: the GTK windows does not show correctly and cannot be used. Any idea?

Its not really clear to me, what you are doing. Do you run Julia in interactive mode or in non-interactive mode?

What works:

• start Julia in interactive mode and run it with two threads.
• run the worker thread using @tspawnat 2 from https://github.com/tro3/ThreadPools.jl. Usually one will spawn the thread in a callback.

More to less working now, thanks.
