I am getting the following error while trying to build opencv with the contrib module

/opencv/opencv_contrib/modules/tracking/include/opencv2/tracking/tracker.hpp:577:11: error: ‘AlgorithmInfo’ does not name a type

The code is latest and pulled just now. After adding a forward declaration class AlgorithmInfo; to the file tracker.hpp that particular error is gone but I am getting other '‘AlgorithmInfo’ does not name a type' errors in other files. Probably AlgorithmInfo is not getting included somehow. Any ideas?

EDIT: After grepping AlgorithmInfo I found that there is no defination of AlgorithmInfo at all!

EDIT2: Comparing to the previous version of code I found AlgorithmInfo is defined at opencv2/core.hpp line 3006. But in the latest code, it is not present there at all!

It makes so much of sense! I could build on latest opencv_contrib module. Thank you!

You should use same versions of opencv and opencv_contrib repositories. Checkout either 3.0.0-beta tag for both, either latest master branch commit.
