I'm running the example project (from the ofxFaceRecognizer addon folder) in the of_v0.9.8_osx_release (downloaded from the of website) in xcode (v. 9.1) with opencv (v. 3.4.0 ) installed on macOS High Sierra and getting the following compiling errors:

Error:

From code:

virtual unsigned char* getPixels();
