Hello. May be you have old version of opecnv.
Please install 4.0.0+
https://github.com/php-opencv/php-opencv/wiki/Installation.-opencv

[Vladimir Goncharov]

Or may be you have opencv without extra modules.

[vicleos]

my installed opencv version is 4.5.1，platform is mac bigSur m1

pkg-config --modversion opencv4

4.5.1

[Vladimir Goncharov]

please run command:

pkg-config --libs opencv4

and try to search opencv_face in the output.

for example I have tihis:

Did you use my docker config: https://github.com/php-opencv/php-opencv-examples/blob/master/docker/ubuntu-20.10_php-7.3_opencv-4.5.0/Dockerfile ?

I have various of tested and reproducible docker configs:

# pkg-config --libs opencv4

-L/usr/local/lib -lopencv_gapi -lopencv_highgui -lopencv_ml -lopencv_objdetect -lopencv_photo -lopencv_stitching -lopencv_video -lopencv_calib3d -lopencv_features2d -lopencv_dnn -lopencv_flann -lopencv_videoio -lopencv_imgcodecs -lopencv_imgproc -lopencv_core

docker images is docker pull php arm64
