undefined reference to `cv::cuda::ORB::create(...)

[C Chien]

I am trying to build opendetection on Unbuntu 16.04-64 bit, with OpenCV 3.2, and get a linking error.

[ 71%] Linking CXX executable od_hog_train

../../common/libod_common.so.1.0: undefined reference to `cv::cuda::ORB::create(int, float, int, int, int, int, int, int, int, bool)'

collect2: error: ld returned 1 exit status

Any suggestion and help will be appreciated.  Let me know if additional information is needed.  Thanks.

Hi Chien ,

I think the error may be due to missing cuda files of features2D (present in opencv). So , I think you should reinstall opencv with cuda dependency .

This is typical error, which is generally encountered when you try installing opencv 3.1 and opencv 3.2 with cuda.
What you can do is, fix all libraries by going through the error messages or could try any other version!
