Closed prismspecs closed 7 years ago

prismspecs commented 7 years ago

Used project generator to include ofxMidi, get

ld: warning: ignoring file /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/System/Library/Frameworks/QuickTime.framework/QuickTime.tbd, missing required architecture x86_64 in file /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/System/Library/Frameworks/QuickTime.framework/QuickTime.tbd Undefined symbols for architecture x86_64: "ofApp::newMidiMessage(ofxMidiMessage&)", referenced from: vtable for ofApp in ofApp.o "non-virtual thunk to ofApp::newMidiMessage(ofxMidiMessage&)", referenced from: vtable for ofApp in ofApp.o ld: symbol(s) not found for architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation)

when I try to build

Which version of OF are you using? I'm not seeing any issues with building ofxMidi in a freshly generated project on macOS 10.12 and OF 0.9.8.

Also, it looks like the error you are getting is within your project ofApp. That particular problem, undefined symbols, usually means you're using something that wasn't declared anywhere and the compiler doesn't know about it. I bet you forgot to either add the function declaration to ofApp.h or you did not implement the same function in ofApp.cpp.

Ah, yes, it appears I did make such a mistake. Thank you!
