Compile error with OpenCV 3.3.0 and xfeatures2d

Question

I downloaded the latest versions of opencv 3.3.0 and opencv_contrib, did the cmake with CUDA support and the make gives me:

....
[ 80%] Built target opencv_xfeatures2d_pch_dephelp
[ 80%] Built target pch_Generate_opencv_xfeatures2d
[ 80%] Building CXX object modules/xfeatures2d/CMakeFiles/opencv_xfeatures2d.dir/src/sift.cpp.o

I'm lost here. I tried updating my cmake from 3.5 to 3.8 and the building stops at the same point.

Thanks for any help!

Answer 1

It seems you got downmodded, yet have not received any feedback.

Your question, I believe, doesn't really belong on stackoverflow. opencv_contrib Is explicitly unstable. The API's for the contained modules are under development and are subject to change at any point in time. Build errors may well arise when building it, too.

I think you'd be better off trying to file a bug report with the module's developers.

Answer 2

removeDuplicatedSorted is just added to opencv master branch 3 days ago and is not back ported to 3.3.0 yet. However sift is updated to it. opencv_contrib tend to sync with master branch. it doesn't have a matching version branch/tag
