cv::KeyPoint is not a member of 'cv'

[highlightz]

My system is Ubuntu 14.04 64bit. My OpenCV version is 2.4.9. Initially, the error is something like "in file BRIEF.cpp: No such file opencv2/imgproc.hpp", and I modify the include to "opencv2/imgproc/imgproc.hpp", which is the real condition in my system. Then, comes the error as "cv::KeyPoint is not a member of 'cv'". Could anybody tells me why this has happened?

Is this happening to the last version committed on May 1?

The last version requires OpenCV 3. Changing the includes is easy, but you may find other issues later.
Try changing

#include <opencv2/imgproc.hpp>

for

#include <opencv2/imgproc/imgproc.hpp>
#include <opencv2/features2d/features2d.hpp>

For those experiencing this issue, you can try to get the previous version of DLib and DBoW2, which is release 1.0:
https://github.com/dorian3d/DLib/releases/tag/v1.0
https://github.com/dorian3d/DBoW2/releases/tag/v1.0
https://github.com/dorian3d/DLoopDetector/releases/tag/v1.0

You can also use the newest opencv version from github.

But then how to install DBoW2? Would it be better if you add those commands in that README file?
