由于安装了很多版本的opencv,希望通过cmake指定链接特定版本的opencv库。 由于我安装的opencv-3.1.0不是在系统默认的目录usr/lib中 CMakeLists.txt 如下
cmake_minimum_required(VERSION 2.8.3) project(rosopencv) ADD_EXECUTABLE(rosopencv rosopencv.cpp) INCLUDE_DIRECTORIES(/home/topeet/programFiles/opencv-3.1.0/include) INCLUDE_DIRECTORIES(/home/topeet/programFiles/opencv-3.1.0/include/opencv) INCLUDE_DIRECTORIES(/home/topeet/programFiles/opencv-3.1.0/include/opencv2) LINK_DIRECTORIES(/home/topeet/programFiles/opencv-3.1.0/lib) SET(CMAKE_LIBRARY_PATH /home/topeet/programFiles/opencv-3.1.0/lib) TARGET_LINK_LIBRARIES(rosopencv libopencv_calib3d.so libopencv_core.so libopencv_features2d.so libopencv_flann.so libopencv_highgui.so libopencv_imgcodecs.so libopencv_imgproc.so libopencv_ml.so libopencv_objdetect.so libopencv_photo.so libopencv_shape.so libopencv_videoio.so libopencv_video.so libopencv_videostab.so)编辑文件 vi /etc/ld.so.conf.d/libc.conf 在文件的末尾加入要调用的动态链接库的路径 /home/topeet/programFiles/opencv-3.1.0/lib 运行ldconfig
在控制台直接使用g++命令能够链接上 但是使用 cmake. make
总是出现 /usr/bin/ld: cannot find -lopencv_calib3d /usr/bin/ld: cannot find -lopencv_core /usr/bin/ld: cannot find -lopencv_features2d
终极解决方案！！ 直接将自定义安装的所有opencv动态链接库文件拷贝到use/lib文件夹下！！ 再执行ldconfig
cmake. make 就能成功了。
