Anyone get an error similar to this when compiling RtAudio with RtMidi? I searched through the code and couldn't even find an variable vtable... I have not idea. Maybe the way my make file is done? I'm just #include-ing not even, calling the function...:(


/home/njb/mus256/hw2/partII/RtMidi.cpp:72: undefined reference to `vtable for RtMidiIn'

/home/njb/mus256/hw2/partII/RtMidi.cpp:74: undefined reference to `RtMidiIn::initialize()'

You didn't setup the flags correctly in the makefile...must have the flags for RtAudio and RtMidi in there....silly, silly Nick
