Trouble with compiling

[hirennearlab]

Hi,

I am a new to opencv. I have compiled opencv, VTK, PCL and all other dependencies. but when I try to compile opendetection, I get the following error:

In file included from /opt/opendetection/common/utils/ODFeatureDetector2D.cpp:6:0:
/opt/opendetection/common/utils/ODFeatureDetector2D.h:16:38: fatal error: opencv2/cudafeatures2d.hpp: No such file or directory
#include <opencv2/cudafeatures2d.hpp>
^
compilation terminated.

I checked the file is there in opencv2 folder.

Could you please suggest a solution?

Thank you.

Regards,
Hiren.

Hi,
This means opencv is not compiled and installed with CUDA. Can you please follow the installation instruction exactly as provided in the website? (http://opendetection.com/installation_instruction.html)

Thanks,

I am having the same problem, I am using CUDA 9.1 and opencv 3.4 and opencv_contrib 3.4 @krips89

opencv cmake flags used:

cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/usr/local -DWITH_CUDA=ON -DCUDA_TOOLKIT_ROOT_DIR=/usr/local/cuda-9.1 -DOPENCV_EXTRA_MODULES_PATH=~/opencv_contrib/modules ..
Was this solved???
