Question

构建dense_flow（https://github.com/yjxiong/dense_flow）时，

Value = @parm

其中../../../3rd-party/opencv-2.4.13/已经建成。

然而，当我做的时候

OpenCV_DIR=../../../3rd-party/opencv-2.4.13/build/ cmake .. -DCUDA_USE_STATIC_CUDA_RUNTIME=OFF

这样的错误就出来了。不知怎的，我试图链接这样的库，但是我找不到那个库。

我遇到了同样的问题，添加了以下符号链接对我有用：

 ln -s /usr/local/cuda-9.2/targets/x86_64-linux/lib/libnppial.so /usr/local/lib/libopencv_dep_nppial.so
 ln -s /usr/local/cuda-9.2/targets/x86_64-linux/lib/libnppicc.so /usr/local/lib/libopencv_dep_nppicc.so
 ln -s /usr/local/cuda-9.2/targets/x86_64-linux/lib/libnppicom.so /usr/local/lib/libopencv_dep_nppicom.so
 ln -s /usr/local/cuda-9.2/targets/x86_64-linux/lib/libnppidei.so /usr/local/lib/libopencv_dep_nppidei.so
 ln -s /usr/local/cuda-9.2/targets/x86_64-linux/lib/libnppif.so /usr/local/lib/libopencv_dep_nppif.so
 ln -s /usr/local/cuda-9.2/targets/x86_64-linux/lib/libnppig.so /usr/local/lib/libopencv_dep_nppig.so
 ln -s /usr/local/cuda-9.2/targets/x86_64-linux/lib/libnppim.so /usr/local/lib/libopencv_dep_nppim.so
 ln -s /usr/local/cuda-9.2/targets/x86_64-linux/lib/libnppist.so /usr/local/lib/libopencv_dep_nppist.so
 ln -s /usr/local/cuda-9.2/targets/x86_64-linux/lib/libnppisu.so /usr/local/lib/libopencv_dep_nppisu.so
 ln -s /usr/local/cuda-9.2/targets/x86_64-linux/lib/libnppitc.so /usr/local/lib/libopencv_dep_nppitc.so

在opencv源目录中的

： ../ cmake / templates / OpenCVConfig.cmake.in：

foreach(l ${OpenCV_CUDA_LIBS_ABSPATH})
get_filename_component(_tmp "${l}" NAME_WE)
string(REGEX REPLACE "^lib" "" _tmp "${tmp}")
if(NOT TARGET "opencv_dep${tmp}") # protect against repeated inclusions
add_library("opencv_dep${tmp}" UNKNOWN IMPORTED)
set_target_properties("opencv_dep${_tmp}" PROPERTIES IMPORTED_LOCATION "${l}")
endif()
endforeach()

像这样

全部评论，无需添加：设置（CUDA_USE_STATIC_CUDA_RUNTIME OFF）与opencv的其他项目链接，将不具有opencv_dep_npp *依赖项

用opencv2.4.13构建dense_flow时找不到nppi系列
