I’m trying to get ofxFaceTracker2 to work with a Raspberry Pi 2 with Raspbian Lite. I’ve made some small steps trying to get it to work, but I keep failing. I believe my problem lies with dlib.
When I try to compile the example-pose project, I end up with the following type of errors (among some other ones):/home/pi/openFrameworks/addons/obj/linuxarmv6l/Release/ofxFaceTracker2/src/ofxFaceTracker2.o: In function `dlib::get_serialized_frontal_faces[abi:cxx11]()': ofxFaceTracker2.cpp:(.text._ZN4dlib28get_serialized_frontal_facesB5cxx11Ev[_ZN4dlib28get_serialized_frontal_facesB5cxx11Ev]+0x1c): undefined reference to `dlib::base64::base64()'When I try to compile the same project, but I add ofxDlib, I get the following errors:
