The function that cannot be found and the function that calls it are given later. Compiler output: Undefined symbols for architecture x86_64: The following is a small error in my own program: I forgot to add MainWindow:: in front of the image processing function mySobel in MainWindow.cpp, which caused the calling function to find it. In this way, Qt configuration OpenCV is basically solved If the compilation still reports an error, there may be a problem with the environment variables at runtime, attach another portal The last picture is very clear

Unfortunately the provided builds for OpenCV do not include a MinGW build any.

Change the lib in the file name to -l and add it as above. I am trying to build OpenCV from source using CLion with MinGW on Windows 10. If there is a small arrow in the lower left corner, don't care about it, and don't care about the version number in the file name. Open lib, which is the dynamic library we need. Click Finder -> Go -> Go to the folder and manually enter the address. Simply add all the 17 dynamic link libraries at once, and finally the library link section no longer reports an errorД«ut where should I find this dynamic library? It's in/usr/local, but you can't enter directly by clicking the icon.

The point is to add the dynamic library path included after the pro file Because there are many libraries involved, and the VideoCapture module is needed to call the camera, the imgproc, core, and highgui modules are not enough, and Qt has been very uncooperative to report errors. What I did is a Qt interface to read the camera, take pictures, then image processing, and finally save as a bmp file program. The portal points to another blog post written by myself Qt CLionД«asically no configuration is required, but the CMakeLists.txt of each project needs to be modified, otherwise symbol(s) not found for architecture x86_64 will appear This should be the basis for the other two IDE configurations.

It is recommended to configure Xcode first under Mac system. This is configured in the Xcode environment. I also tried setting up Anaconda and was able to get OpenCV to work, however. Note that if the configuration of Other Linker flags in the last step is not successful, you can try to set it to -all_load Clion keeps saying: If something is still not clear after reading those. The specific steps are written by this great god, My own opencv is compiled and installed through CMake. The following is a summary of some special problems that I have encountered (and it is difficult to find on the Internet).
