Good day everyone, thanks for taking the time to look into my question. I've started implementing an ANN classification based on OpenCV but I have this error:

  • error LNK2019: symbole externe non résolu "public: static class cv::Ptr<class cv::ml::ann_mlp=""> __cdecl cv::ml::ANN_MLP::create(void)" (?create@ANN_MLP@ml@cv@@SA?AV?$Ptr@VANN_MLP@ml@cv@@@3@XZ) référencé dans la fonction main
  • error LNK1120: 2 externes non résolus

Thanks you for your help.

Thank you for your quick replay. I add this lib but nothing change

What happens when you add this next line to the top of your .cpp file:

#pragma comment(lib, "opencv_world340.lib")

If this doesn't help, then post your code.
