Some questions about enviroments

[HigashikataZhangsuke]

I am using the YOLO+KCF but I do not know the opencv version you used, so there will be two questions: If I use the detector you compiled before then I would get
./detect: symbol lookup error: ./detect: undefined symbol: _ZN8DetectorC1ENSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEES5_i
and when I choose to compile by myself,there would be this error
