Hello everybody!

I have a problem in the Opencv 4.2.0 Face Recognizer example: https://docs.opencv.org/3.4/da/d60/tu...

I get an error: undefined reference to `cv::face::EigenFaceRecognizer::create(int, double)'

I use Qt Creator, and I added all the library what the example need.

What can be the problem?

Please Help me!

Do you use opencv or opencv_contrib? What is your cmakelist? you need opencv_face in lib list
