目录
一、安装vscode
我使用anaconda安装的，可以参考vscode的主页，有安装方式。
二、安装C/C++插件
按Ctrl + shift + X，搜索C/C++并安装。安装它就行。
三、配置调试和编译文件
3.1 tasks.json文件----生成out文件
为了方便在VScode里编译C++代码，我们可以将类似g++ -g main.cpp等g++命令写入VScode的任务系统。
按ctrl+shift+p打开命令行，输入Tasks: Run task，回车！！！，会出现如下提示：
No task to run found. configure tasks...
再回车，
Create tasks.json file from template
然后选择：
Others Example to run an arbitrary external command.
生成默认的tasks.json文件如下：
{
// See https://go.microsoft.com/fwlink/?LinkId=733558
// for the documentation about the tasks.json format
"version": "2.0.0",
"tasks": [
{
"label": "build",
"type": "shell",
"command": "g++",
"args": ["-g", "${file}", "-o", "${fileBasenameNoExtension}.out"]
}
]
}这里的label为任务名，我们将”label"= "echo"改为”label"= "build"。
由于我们的指令是g++，这里将”command“=”echo Hello“改为”command“=”g++“。
然后添加g++的参数args。如果我们的g++指令为：g++ -g main.cpp，这里可以把参数设置为如下：
3.2 launch.json文件----执行out文件
选中文件夹/cpp文件，按Ctrl+shift+D，点击左侧的Debug按钮，选择添加配置（Add configuration）,然后选择C++（GDB/LLDB)回车！！将自动生成launch.json文件，修改内容如下：
"program": "enter program name, for example ${workspaceFolder}/a.out",
改为
"program": "${workspaceFolder}/${fileBasenameNoExtension}.out",
{
// Use IntelliSense to learn about possible attributes.
// Hover to view descriptions of existing attributes.
// For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
"version": "0.2.0",
"configurations": [
{
"name": "(gdb) Launch",
"type": "cppdbg",
"request": "launch",
"program": "${workspaceFolder}/${fileBasenameNoExtension}.out",
"args": [],
"stopAtEntry": false,
"cwd": "${workspaceFolder}",
"environment": [],
"externalConsole": true,
"MIMode": "gdb",
"preLaunchTask":"build",
"setupCommands": [
{
"description": "Enable pretty-printing for gdb",
"text": "-enable-pretty-printing",
"ignoreFailures": true
}
]
}
]
}"preLaunchTask":"build"，这个参数必须有，否则会报错，在debug的时候，说lauch：file.out文件不存在。
四 执行
F5
五 OPENCV编译环境
5.1 配置opencv
去这里 https://github.com/opencv/opencv/releases 下载，tar.tg文件。加压。
cd opencv/cmake
cmake ..
suido make
sudo make install5.2 配置vscode环境
5.2.1 c_cpp_properties.json
按ctrl+shift+p，输入edit，选择C/C++:edit configuration(json)，会弹出c_cpp_properties.json。他是配置外部环境的。
{
"configurations": [
{
"name": "Linux",
"includePath": [
"${workspaceFolder}/**"
],
"defines": [],
"compilerPath": "/usr/bin/gcc",
"cStandard": "c11",
"cppStandard": "c++17",
"intelliSenseMode": "clang-x64"
}
],
"version": 4
}修改它
"includePath": [
"${workspaceFolder}/**",
"/usr/local/include", //请确保你的opencv opencv2头文件夹安装在这个目录5.2.2 task.josn
tasks.json里面修改的是参数问题，我还没试试那个好使
"args": [
"-g",
"${workspaceRoot}/test.cpp",
"-L", "/usr/local/opencv3.4/lib/lib*",
"-o",
"run"
],
"args": [
"-g", "-std=c++11", "${file}", "-o", "${fileBasenameNoExtension}.o",// 设置动态链接库
"-I", "/usr/local/include",
"-I", "/usr/local/include/opencv",
"-I", "/usr/local/include/opencv2",
"-L", "/usr/local/lib",
"-l", "opencv_core",
"-l", "opencv_imgproc",
"-l", "opencv_imgcodecs",
"-l", "opencv_video",
"-l", "opencv_ml",
"-l", "opencv_highgui",
"-l", "opencv_objdetect",
"-l", "opencv_flann",
"-l", "opencv_imgcodecs",
"-l", "opencv_photo",
"-l", "opencv_videoio"
],// 编译命令参数
5.2.3 libjasper.so.1
缺少libjasper.so.1，有啥办法，安装呗。
命令如下：
sudo add-apt-repository "deb http://security.ubuntu.com/ubuntu xenial-security main"
sudo apt update
sudo apt install libjasper1 libjasper-dev
