Hi, please could you confirm what version combination OpenCV and OpenCV Contrib do you use ?

OpenCV: 4.8.1 (2c1ec4245dc793153c50fcbd255863dd1382c961)

OpenCV 4.8.1 is 5199850039ad23f1f0e6cccea5061a9fea5efca6.
2c1ec4245dc793153c50fcbd255863dd1382c961 is on 4.x branch.

And there are no information about OpenCV contrib.

This problem is confirmed with my ubuntu 23.10 environment. Maybe it is same reason.

  1. git clone opencv and git checkout 4.8.1. ( it is 4.8.1 tag)
  2. git clone opencv_contrib ( it is 4.x branch).
  3. cmake and build

In this case, opencv is based on 4.8.1, opencv/opencv@a287605 is not installed.
However opencv_contrib is based on 4.x branch. b9a460b is installed.

So to occur compile error is not unnatural.
If you want to use OpenCV 4.8.1 with contrib, please could you try cd opencv_contrib ; git checkout 4.8.1.
