Eclipse/C++ cannot find header files -


i've added macos x c++ linker , gcc c++ compiler includes , libraries libraries , paths, i'm still unable #include library path , file i've added.

code:
#include <opencv2/text/ocr.hpp>

error:

fatal error: 'opencv2/text/ocr.hpp' file not found


eclipse setup: (project > properties > c/c++ build > settings)
macos x c++ linker > libraries
library search paths:
/usr/local/cellar/opencv3/3.1.0_4/lib
/usr/local/cellar/opencv3/3.1.0_4/include/opencv2
/usr/local/cellar/opencv3/3.1.0_4/include/opencv2/text
libraries:
ocr

gcc c++ compiler > includes
include paths:
/usr/local/cellar/opencv3

mac file structure:
ocr.hpp exists in /usr/local/cellar/opencv3/3.1.0_4/include/opencv2/text

my thoughts:

  • it seems eclipse still looking in ~/cellar/opencv instead of ~/cellar/opencv3.
  • because can #include libraries in /usr/local/cellar/opencv/2.4.13.1/include/opencv2 without adding paths eclipse project settings.
  • but cannot #include libraries /usr/local/cellar/opencv3/3.1.0_4/include/opencv2

i'm used working in ruby library management super easy, it's frying brain little trying things setup in c++. appreciated.

solution:

projects > properties > c/c++ general > paths , symbols > gnu c++
changed /usr/local/cellar/opencv /usr/local/cellar/opencv3

... > library paths
removed paths , added /usr/local/cellar/opencv3.

then included:
#include <3.1.0_4/include/opencv2/text/ocr.hpp>

thanks assistance in comments.
