本文参考:vscode一键配置C/C++多个C及CPP文件编译与tasks.json和launch.json原理
上一篇文章我们了解了VScode的工作原理,但是实际项目肯定是由多个源文件和模块组成。此时可以通过CMake进行配置工程,然后进行make编译。
上一篇文章我们知道VScode的工作原理主要依赖执行任务,即task.json
。通过CMake配置的工程我们只需要执行如下指令,即可完成整个项目的编译工作。
CMake . && make
CMake输出目录依旧为:build
。所以任务主要分为两步:第一步创建Build
目录,第二步在Build目录执行CMake指令:CMake ../
创建build目录
{
"type":"shell",
"label": "mkBuild",
"command":"mkdir",
"args": [
//这里需要指定参数p,否则如果build目录存在则任务会报错
"-p",
"build"
],
"options": {
"cwd": "${workspaceFolder}"
},
},
在build目录执行CMake
{
"type":"shell",
"label": "executeCmake",
"command":"cmake",
"args": [
"../",
],
"options": {
"cwd": "${workspaceFolder}/build"
},
//这里需要指定依赖的任务mkBuild,由mkBuild创建build目录
"dependsOn":"mkBuild"
},
在build目录执行make
{
"type":"shell",
"label": "execMake",
"command":"make",
"args": [
],
"options": {
"cwd": "${workspaceFolder}/build"
},
//依赖CMake任务
"dependsOn":"executeCmake"
}
此时在launch.json
里面指定任务execMake
即可。
"preLaunchTask": "execMake",
配置完成之后按运行F5调试即可,如果需要调试CMake一定需要指定set(CMAKE_BUILD_TYPE "Debug")
,否则将不可调试。
下面是完整的配置文件:
task.json
{
"tasks": [
{
"type":"shell",
"label": "mkBuild",
"command":"mkdir",
"args": [
"-p",
"build"
],
"options": {
"cwd": "${workspaceFolder}"
},
},
{
"type":"shell",
"label": "executeCmake",
"command":"cmake",
"args": [
"../",
],
"options": {
"cwd": "${workspaceFolder}/build"
},
"dependsOn":"mkBuild"
},
{
"type":"shell",
"label": "execMake",
"command":"make",
"args": [
],
"options": {
"cwd": "${workspaceFolder}/build"
},
"dependsOn":"executeCmake"
}
],
"version": "2.0.0"
}
launch.json
{

由于CMakeLists.txt
的代码不具有通用性,所以这里暂时不贴出。如果不懂CMake的可以参考:一文读懂CMake
