Hi there,
I'm trying to build traincascade in VSC using MacOS. I managed to get the annotation tool to work perfectly fine, but when I go to actually train my positive and negative images, I keep receiving the following error:
Undefined symbols for architecture x86_64: [build] "CvCascadeParams::scanAttr(std::__1::basic_string<char, std::__1::char_traits<char="">, std::__1::allocator<char> >, std::__1::basic_string<char, std::__1::char_traits<char="">, std::__1::allocator<char> >)", referenced from: [build] _main in traincascade.cpp.o [build] "CvCascadeParams::CvCascadeParams()", referenced from: [build] _main in traincascade.cpp.o [build] CvCascadeClassifier::CvCascadeClassifier() in traincascade.cpp.o [build] "CvHOGFeatureParams::CvHOGFeatureParams()", referenced from: [build] std::__1::__compressed_pair_elem<cvhogfeatureparams, 1,="" false="">::__compressed_pair_elem(std::__1::__value_init_tag) in traincascade.cpp.o [build] "CvLBPFeatureParams::CvLBPFeatureParams()", referenced from: [build] std::__1::__compressed_pair_elem<cvlbpfeatureparams, 1,="" false="">::__compressed_pair_elem(std::__1::__value_init_tag) in traincascade.cpp.o [build] "CvCascadeClassifier::train(std::__1::basic_string<char, std::__1::char_traits<char="">, std::__1::allocator<char> >, std::__1::basic_string<char, std::__1::char_traits<char="">, std::__1::allocator<char> >, std::__1::basic_string<char, std::__1::char_traits<char="">, std::__1::allocator<char> >, int, int, int, int, int, CvCascadeParams const&, CvFeatureParams const&, CvCascadeBoostParams const&, bool, double)", referenced from: [build] _main in traincascade.cpp.o [build] "CvHaarFeatureParams::CvHaarFeatureParams()", referenced from: [build] std::__1::__compressed_pair_elem<cvhaarfeatureparams, 1,="" false="">::__compressed_pair_elem(std::__1::__value_init_tag) in traincascade.cpp.o [build] "CvCascadeBoostParams::scanAttr(std::__1::basic_string<char, std::__1::char_traits<char="">, std::__1::allocator<char> >, std::__1::basic_string<char, std::__1::char_traits<char="">, std::__1::allocator<char> >)", referenced from: [build] _main in traincascade.cpp.o [build] "CvCascadeBoostParams::CvCascadeBoostParams()", referenced from: [build] _main in traincascade.cpp.o [build] "CvCascadeImageReader::NegReader::NegReader()", referenced from: [build] CvCascadeImageReader::CvCascadeImageReader() in traincascade.cpp.o [build] "CvCascadeImageReader::PosReader::PosReader()", referenced from: [build] CvCascadeImageReader::CvCascadeImageReader() in traincascade.cpp.o [build] "CvCascadeImageReader::PosReader::~PosReader()", referenced from: [build] CvCascadeImageReader::CvCascadeImageReader() in traincascade.cpp.o [build] CvCascadeImageReader::~CvCascadeImageReader() in traincascade.cpp.o [build] "CvCascadeParams::printDefaults() const", referenced from: [build] _main in traincascade.cpp.o [build] "CvCascadeBoostParams::printDefaults() const", referenced from: [build] _main in traincascade.cpp.o [build] "vtable for CvParams", referenced from: [build] CvParams::~CvParams() in traincascade.cpp.o [build] NOTE: a missing vtable usually means the first non-inline virtual member function has no definition.

Really not sure what's going on here. When I run pkg-config --cflags --libs opencv4 I get:
