Compilation for only CPU mode

[kushalvyas]

I want to compile the library for a plain CPU . Installation asks for Opencv_contrib with CUDA support.

Scanning dependencies of target od_common [ 30%] [ 32%] [ 34%] Building CXX object common/CMakeFiles/od_common.dir/pipeline/ObjectDetector.cpp.o [ 36%] Building CXX object common/CMakeFiles/od_common.dir/pipeline/ODScene.cpp.o Building CXX object common/CMakeFiles/od_common.dir/utils/utils.cpp.o Building CXX object common/CMakeFiles/od_common.dir/utils/ODFeatureDetector2D.cpp.o In file included from open_detection/opendetection/common/utils/ODFeatureDetector2D.cpp:6:0: open_detection/opendetection/common/utils/ODFeatureDetector2D.h:16:38: fatal error: opencv2/cudafeatures2d.hpp: No such file or directory #include <opencv2/cudafeatures2d.hpp> ^ compilation terminated. make[2]: *** [common/CMakeFiles/od_common.dir/utils/ODFeatureDetector2D.cpp.o] Error 1 make[2]: *** Waiting for unfinished jobs.... make[1]: *** [common/CMakeFiles/od_common.dir/all] Error 2 make: *** [all] Error 2

Any hack around this ?

Hi kushal, If go through the code base of OD many of the functions require cuda support and moreover you also need to install opencv along with cudafeatures2d .

Since CUDA is one of the dependancy, so you will be needing:

• A CUDA-capable GPU
  

• A supported version of Microsoft Windows
  

• A supported version of Microsoft Visual Studio
  

• the NVIDIA CUDA Toolkit (available at http://developer.nvidia.com/cuda-downloads)
