Hey all,
I’m trying to navigate my way around writing a simple command line app with Juce. The problem I’m running into is I keep getting an “Assertion failure in juce_mac_CoreMidi.cpp:259” if I try to call MidiInput::getAvailableDevices();
like auto midiInputs = MidiInput::getAvailableDevices();
It’s the only line in my main function. Is there something else I need to instantiate first or something?
I’m working on MacOS High Sierra, running XCode 10.1, JUCE 5.4.4.
If you’re writing a command-line app then you need to initialise the message loop for the CoreMidi stuff to work correctly. Add a ScopedJuceInitialiser_GUI object to the top of your main() function which will take care of starting and shutting down the event loop.
Out of curiosity, how was I ever supposed to know that? Is there some comprehensive documentation I should be reading that explains basic requirements like that?
