OpenCV 相关报错

一，  undefined reference to `cv::ocl::integral(cv::ocl::oclMat const&, cv::ocl::oclMat&)'

I solved this problem by change the order of target_link_libraries, like this:TARGET_LINK_LIBRARIES( test ${OpenCV_LIBS} ${catkin_LIBRARIES}OpenCV first, then catkin

change the order of target_link_libraries

把OpenCV lib 放在前面


target_link_libraries(homography ${OpenCV_LIBRARIES} ${catkin_LIBRARIES} )
