Some installation errors

[warmhug]

Follow this install opencv3, then run brew install boost to install latest version of boost 1.63.0. Then run:

mkdir release && cd release
cmake ..
make

# begin throw error

fatal error: 'opencv2/core/core.hpp' file not found
#include <opencv2/core/core.hpp>
         ^

make[2]: *** [sse/CMakeFiles/opensse.dir/io/filelist.cpp.o] Error 1
make[1]: *** [sse/CMakeFiles/opensse.dir/all] Error 2
make: *** [all] Error 2

Then I follow this add include_directories(/usr/local/opt/opencv3/include) to CMakeLists.txt file, run cmake .. and make, it outputs the new error as follows

What is the problem?

I installed OpenCV 3.0 and boost in /usr/local/ path, include files are under /usr/local/include folder and libraries are under /usr/local/lib.

If you installed them in other path, please open top CMakeLists.txt file and change below lines to your path:

include_directories(/usr/local/include)

link_directories(/usr/local/lib)

[warmhug]

This is partially modified of CMakeLists.txt file

include_directories(/usr/local/opt/opencv3/include /usr/local/Cellar/boost/1.63.0/include/boost)
include_directories(..)
include_directories(${PROJECT_SOURCE_DIR}/sse)

link_directories(/usr/local/opt/opencv3/lib /usr/local/Cellar/boost/1.63.0/lib)

And it also throw errors

It seems like boost lib cannot be found, please go into '/usr/local/Cellar/boost/1.63.0/lib' folder, and make sure boost_thread exist, maybe named libboost_thread.dylib or libboost_thread-mt.dylib and change below line:

set(REQUIRED_LIB opencv_core opencv_imgproc opencv_imgcodecs opencv_highgui opencv_features2d opencv_ml boost_thread boost_system)

[warmhug]

I change boost_thread to boost_thread-mt, It seems to be working fine. Run make, it outputs info as follows

Thanks and suggest you can update the wiki document for this situation.

Different boost makes different library, this is why I am working on removing boost from core OpenSSE library. It is hard to remove OpenCV, I added docker support to make life happy
