1 g++ opencv_test.cpp -o opencv_test `pkg-config --cflags --libs opencv` 2 ./opencv_test test.jpg
备注：pkg-config选项
--cflags 它是用来指定程序在编译时所需要头文件所在的目录
--libs 则是指定程序在链接时所需要的动态链接库的目录
在程序同目录下创建CMakeLists.txt
1 #文件地址(下载源码安装包中)：/opencv-3.4.1/samples/cpp/example_cmake/ 2 3 # cmake needs this line 4 cmake_minimum_required(VERSION 2.8) 5 6 # Define project name 7 project(opencv_example_project) 8 9 # Find OpenCV, you may need to set OpenCV_DIR variable 10 # to the absolute path to the directory containing OpenCVConfig.cmake file 11 # via the command line or GUI 12 find_package(OpenCV REQUIRED) 13 14 # If the package has been found, several variables will 15 # be set, you can find the full list with descriptions 16 # in the OpenCVConfig.cmake file. 17 # Print some message showing some of them 18 message(STATUS "OpenCV library status:") 19 message(STATUS " version: ${OpenCV_VERSION}") 20 message(STATUS " libraries: ${OpenCV_LIBS}") 21 message(STATUS " include path: ${OpenCV_INCLUDE_DIRS}") 22 23 if(CMAKE_VERSION VERSION_LESS "2.8.11") 24 # Add OpenCV headers location to your include paths 25 include_directories(${OpenCV_INCLUDE_DIRS}) 26 endif() 27 28 # Declare the executable target built from your sources 29 add_executable(opencv_example example.cpp) 30 31 # Link your application with OpenCV libraries 32 target_link_libraries(opencv_example ${OpenCV_LIBS})
然后执行：
1 cmake . 2 make 3 ./opencv_example test.jpg
