g++ opencv.cpp -o opencv pkg-config --libs --cflags opencv

errors :

g++: error: missing argument to ‘-l’

seems, your cmdline is missing the backticks around the pkg-config parts. see haris' answer below

the backticks are the problem ;) had the same problem yesterday and took me a while to find the reason...

Just try this command

g++ -I/usr/local/include/opencv -I/usr/local/include/opencv2 -L/usr/local/lib/ -g -o binaryName  main.cpp -lopencv_core -lopencv_imgproc -lopencv_highgui -lopencv_ml -lopencv_video -lopencv_features2d -lopencv_calib3d -lopencv_objdetect -lopencv_contrib -lopencv_legacy

assumes you have installed in /usr/local directory.

g++ `pkg-config --cflags --libs opencv` opencv.cpp -o opencv
