ubuntu 编译c++运行的几个方法，基于vscode操作

方法1：基于cmake编译

1.一个CMakeLists.txt

cmake_minimum_required(VERSION 2.8)
project( DisplayImage )
add_executable( DisplayImage DisplayImage.cpp )

find_package( OpenCV REQUIRED )
include_directories( ${OpenCV_INCLUDE_DIRS} )

target_link_libraries( DisplayImage ${OpenCV_LIBS} )

2. 在当前文件夹命令: cmake .
   形成编译文件
3. 编译命令 make
   产生一个 可应用文件 DisplayImage
4. 输入 ./DisplayImage

方法2

打开 工作文件夹
编写.cpp .h
ctrl shift d 打开lauch.json

ctrl shift p 打开tasks.json
这个版本的和”name”: “g++ – Build and debug active file”,对应

“version”: “2.0.0”,
“tasks”: [
{
“label”: “echo”,
“type”: “shell”,
“command”: “echo Hello”
},
{
“type”: “shell”,
“label”: “g++ build active file”,

}

默认生成a.exe程序
