I'm trying to compile this example
https://github.com/opencv/opencv_contrib/blob/master/modules/text/samples/textdetection.cpp
I changed the top three lines
#include "opencv2/text.hpp"
#include "opencv2/highgui.hpp"
#include "opencv2/imgproc.hpp"
to
#include "/home/david/c/opencv-3.2.0/include/opencv2/opencv.hpp"
I get the following compilation error
david@ubuntu:~/c$ gcc opencv.cpp
In file included from opencv.cpp:1:0:
/home/david/c/opencv-3.2.0/include/opencv2/opencv.hpp:48:38: fatal error: opencv2/opencv_modules.hpp: No such file or directory
compilation terminated.
I've been away from c++ for years, what am I doing wrong?
