Using VSCode to develop high-level C/C++ programs generally requires configuration tasks.jsonand launch.jsonthese two files
① tasks.json : compiler build configuration file;
② launch.json : debugger configuration configuration file;
1. Single file compilation
Compile the file firstg++ -g main.cpp -o main.exe
1.1 Create tasks.json compiler build configuration file
Select "Terminal → Configure Tasks" in the menu bar to generate, the configuration is as follows (mainly pay attention to the g++ path location)
{
"version": "2.0.0",
"tasks": [
{
"type": "cppbuild",
"label": "C/C++: g++.exe build active file",
"command": "F:\\mingw64\\bin\\g++.exe",
"args": [
"-fdiagnostics-color=always",
"-g",
"${file}",
"-o",
"${fileDirname}\\${fileBasenameNoExtension}.exe"
],
"options": {
"cwd": "${fileDirname}"
},
"problemMatcher": [
"$gcc"
],
"group": {
"kind": "build",
"isDefault": true
},
"detail": "compiler: F:\\mingw64\\bin\\g++.exe"
}
]
}
1.2 Create launch.json compiler build configuration file
The relevant configuration is as follows:
{
// 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", // 配置名称，将会在启动配置的下拉菜单中显示
"type": "cppdbg", // 配置类型，这里只能为cppdbg
"request": "launch", // 请求配置类型，可以为launch（启动）或attach（附加）
"program": "${fileDirname}/${fileBasenameNoExtension}.exe", //将要进行调试的程序的路径
"args": [], // 程序调试时传递给程序的命令行参数，一般设为空即可
"stopAtEntry": false, // 设为true时程序将暂停在程序入口处，一般设置为false
"cwd": "${workspaceFolder}", // 调试程序时的工作目录，一般为${workspaceFolder}即代码所在目录
"environment": [],
"externalConsole": false, // 调试时是否显示控制台窗口，一般设置为true显示控制台====用true的时候需要在return的上面加getchar（）；
"MIMode": "gdb",
"miDebuggerPath": "F:/mingw64/bin/gdb.exe", // miDebugger的路径，注意这里要与MinGw的路径对应
"setupCommands": [
{
"description": "Enable pretty-printing for gdb",
"text": "-enable-pretty-printing",
"ignoreFailures": false
}
],
"preLaunchTask": "C/C++: g++.exe build active file", // 调试会话开始前执行的任务，一般为编译程序，c++为g++, c为gcc
}
]
}
2. Multi-file compilation
Compile the file firstg++ -g main.cpp swap.cpp -o mutil_swap
2.1 Modify launch.json configuration
Mainly "program"modify the parameters and comment out"preLaunchTask"
The relevant configuration is as follows:
{
// 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", // 配置名称，将会在启动配置的下拉菜单中显示
"type": "cppdbg", // 配置类型，这里只能为cppdbg
"request": "launch", // 请求配置类型，可以为launch（启动）或attach（附加）
"program": "${fileDirname}/mutil_swap.exe", //将要进行调试的程序的路径
"args": [], // 程序调试时传递给程序的命令行参数，一般设为空即可
"stopAtEntry": false, // 设为true时程序将暂停在程序入口处，一般设置为false
"cwd": "${workspaceFolder}", // 调试程序时的工作目录，一般为${workspaceFolder}即代码所在目录
"environment": [],
"externalConsole": false, // 调试时是否显示控制台窗口，一般设置为true显示控制台====用true的时候需要在return的上面加getchar（）；
"MIMode": "gdb",
"miDebuggerPath": "F:/mingw64/bin/gdb.exe", // miDebugger的路径，注意这里要与MinGw的路径对应
"setupCommands": [
{
"description": "Enable pretty-printing for gdb",
"text": "-enable-pretty-printing",
"ignoreFailures": false
}
],
// "preLaunchTask": "C/C++: g++.exe build active file", // 调试会话开始前执行的任务，一般为编译程序，c++为g++, c为gcc
}
]
}
3. CMake compiles directly
3.1 CreateCMakelists.txt
project(MYSWAP) # 工程名
add_executable(my_cmake_swap main.cpp swap.cpp) # 生成的cmake.exe文件， 文件组成
3.2 Other Configuration
ctrl + shift + pInput CMakeSelect CMake: Configure, and then select Compiler
to end the above process and generate a buildfile
3.3 Generateexe
Open the terminal and follow the steps to enter
cd .\build\
cmake ..
mingw32-cmake.exe
At this point, buildthe folder appearsmy_cmake_swap.exe
3.4 Modify launch.jsonthe following parameters in
"program": "${fileDirname}/build/my_cmake_swap.exe", //将要进行调试的程序的路径
// "preLaunchTask": "C/C++: g++.exe build active file", // 调试会话开始前执行的任务，一般为编译程序，c++为g++, c为gcc
It can also be achieved by using
4. CMake compiles using task.json configuration
Using task.jsondirect configuration CMake, dependsOnthe parameter corresponds to cmakethe execution cmake .. , and makethe execution ismingw32-make.exe
{
"version": "2.0.0",
"options": {
"cwd": "${workspaceFolder}/build"
},
"tasks": [
{
"type": "shell",
"label": "cmake",
"command": "cmake",
"args": [
".."
],
},
{
"label": "make",
"group": {
"kind": "build",
"isDefault": true
},
"command": "mingw32-make.exe", //windows，linux 命令为 make
"args": [
],
},
{
"label": "Build",
"dependsOn":[
"cmake",
"make"
]
}
],
}
Corresponding to the modification launch.json, the modification is mainly related "program"to "preLaunchTask"the parameter
