IOutput is an interface where their methods are declared at ioutput.h and must be implemented somewhere. I found out they were implemented at cvsamplesoutput.cpp so we just need ask gcc to compile that file. For that the correct command should be:

g++ `pkg-config --libs --cflags opencv | sed 's/libtbb\.dylib/tbb/' ` -I. -o mergevec mergevec.cpp cvboost.cpp cvcommon.cpp cvsamples.cpp cvhaarclassifier.cpp cvhaartraining.cpp cvsamplesoutput.cpp -lopencv_core -lopencv_calib3d -lopencv_imgproc -lopencv_highgui -lopencv_objdetect
