trying to include RtMidi

herrgross

Hello everybody,

I'm working with QT Creator on MacOsX.
I am trying to use some MIDI - Input in a project, so I found the RtMidi class.
First I am trying to do a little test project to see how (and if) it works.
Having copied the RtMidi.cpp and the RtMidi.h into my projectfolder I included them into my project.
Running a little bit of testcode I get the message:
" RtMidiOut: no compiled API support found"
I think that the CoreMIDI, CoreAudio and CoreFoundation are not correctly linked (sorry, but I do, as quite a beginner, not even know what this exactly means...)
On the RtMidi Tutorialpage (https://www.music.mcgill.ca/~gary/rtmidi/) it says:
"In order to compile RtMidi for a specific OS and API, it is necessary to supply the appropriate preprocessor definition and library within the compiler statement:"
with the given example:
"g++ -Wall -D__MACOSX_CORE__ -o midiprobe midiprobe.cpp RtMidi.cpp -framework CoreMIDI -framework CoreAudio -framework CoreFoundation"
Where and how should I include that to my project?
Any help appreciated,
thanks,
Michael

Solution found:
in .pro file add:

LIBS += -framework CoreFoundation
LIBS += -framework CoreMIDI
LIBS += -framework CoreAudio

in RtMidi.h add:

#define __MACOSX_CORE__

that's it...
Thanks for helping

For qmake I do:
LIBS += -framework CoreMidi

@mpergand that's what I tried in my project file:
LIBS += -framework CoreFoundation
LIBS += -framework CoreMIDI
LIBS += -framework CoreAudio

but it does not work...

I don't use rtmidi but to me
" RtMidiOut: no compiled API support found"
looks like a bug with rtmidi

I use my own set of classes.

Maybe the issue is specific to your mac config (arm proc ?)
You have to seach the internet to see if others have the same issue as you.

can you recommand something?

maybe PortMidi ?
but know nothing about it.

Hi,

Rather than modifying the header, you can add the define in your project file:

DEFINES += __MACOSX_CORE__
