Hi all,

Following the guideline https://www.learnopencv.com/install-o..., In MacOS Mojave, I have successfully built C++ OpenCV4 dynamic libs from github source. I tried to run a simple program (which is shown below) and it worked well

#include <iostream>
#include <opencv2/opencv.hpp>
using namespace std;
int main(void)
{
  std::cout << cv::getBuildInformation() << std::endl;
}

Then, I tried to build C++ static lib and it was successful too (I turn off CMAKE option BUILD_SHARED_LIBS). However, when I run the same code above, I got the following errors. Could somebody please help me? I would like to use static libs rather than dynamic libs.

Since you are compiling the code with static libraries, you need to link all necessary libraries in you command. According to the error message, you are missing itt library, normally, it should be in ./build/share/OpenCV/3rdparty/lib with name libittnotify.a
