Solution

  • You need to link your code with RtAudio library, so add -lrtAudio to your compile command:

    g++ -Wall -D__MACOSX_CORE__ -o probe RtAudio.cpp -framework CoreAudio -lpthread -lrtAudio

    And you have included two RtAudio, one "rtaudio.cpp" and two RtAudio.cpp, you should clear rtaudio.cpp, because you included #include "RtAudio.h" with uppercase in your main
