一、命令行Command Line

1 g++ opencv_test.cpp -o opencv_test `pkg-config --cflags --libs opencv`
2 ./opencv_test test.jpg

備註：pkg-config選項
--cflags 它是用來指定程序在編譯時所需要頭文件所在的目錄
--libs 則是指定程序在鏈接時所需要的動態鏈接庫的目錄

二、CMake工具編譯

在程序同目錄下創建CMakeLists.txt

 1 #文件地址(下載源碼安裝包中)：/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})

然後執行：

1 cmake . 
2 make 
3 ./opencv_example test.jpg
