On Ubuntu 14.4 with OpenCV 3.1.0 : I'm trying to compile and run this file

but I don't know what to write in the file to make it executable

I found this but it doesn't work :

LIBS="-lopencv_imgproc -lopencv_highgui -lopencv_core -lopencv_objdetect -lopencv_contrib"
g++ -I/usr/local/include/opencv -I/usr/local/include/opencv2 -L/usr/lib -L/usr/local/lib -fpic -Wall -c "untitled.cpp" $LIBS

g++ -shared -I/usr/local/include/opencv -I/usr/local/include/opencv2 -o untitled.o -L/usr/local/lib $LIBS

g++ -I/usr/local/include/opencv -I/usr/local/include/opencv2 -o untitled untitled.o -L/usr/local/lib $LIBS

exit 0

  • you'll need to rebuild opencv with opencv_contrib (please see readme there for build instructions)
  • please see 3.1 docs , not the old 3.0 ones
  • LIBS="-lopencv_imgproc -lopencv_imgcodecs -lopencv_highgui -lopencv_core -lopencv_objdetect -lopencv_face"
  • the old 2.4 samples won't run as-is, please have a look at the current samples

after changing the permissions to both build/modules and opencv_contrib/modules with sudo chmod 777 modules there 's an error bash: /modules: Permission denied
