int main(){
    cout << "openCV Version: " << CV_VERSION << endl;
    
    Mat image = imread("img.jpg", IMREAD_COLOR);

I use opencv in these environment: M1 Mac(ver.13.4(22F66)), Xcode(Version 14.3.1 (14E300c)), C++

And i install and build opencv in this routine.

• git clone opencv & opencv_extra_modules
• brew install cmake
• cmake & make & sudo make install

And i set xcode like this.

• header search path: ".../opencv/install/include/**"
• library search path: ".../opencv/install/lib"
• other linker flags: output from "pkg-config —cflags —libs opencv4" in terminal. (install folder have cmake install things cause i have cmake option. CMAKE_INSTALL_PREFIX=.../opencv/install)

I think there are some problems related to dynamic library link... But i cannot sure about this exactly.

I tried xcode setting(RunPath Search Paths: "…/install/lib" & Signing&Capabilities-Rumtime Exception-Disable Library Validation CHECK). And add Environmanet Variable and PKG_CONFIG_PATH to my .zshrc file.

From search, i recovered this error doesn't matter to me. I just want to make cv code and check that result in xcode. So, in my case the only one to do is add those 2 code. This shows my result Window correctly.

namedWindow("Original Image");
imshow("Original Image", image);
waitKey(0); //add this
destroyAllWindows(); //add this
