解析VScode在Windows环境下c_cpp_properties.json文件配置问题(推荐)

一、c_cpp_properties.json文件是什么？

c_cpp_properties.json文件是VS Code的配置文件之一，它被用来配置C++的调试器和语言服务器等属性。它通常是一个JSON格式的文件，包含了调试器和语言服务器的路径、编译器的路径以及代码库的路径等等。

二、如何配置c_cpp_properties.json文件？

打开VS Code，并打开要配置的C++项目。
在VS Code的左侧边栏中，点击“文件”按钮，然后选择“首选项” -> “设置”或使用快捷键Ctrl + ,，打开用户设置面板。
在搜索框中输入“C++”，在搜索结果中选择“Edit in settings.json”，打开settings.json文件。
在settings.json文件中，找到或创建一个名为“C_Cpp.default.configuration”的项，并将其设置为您要使用的c_cpp_properties.json文件的路径，例如：

"C_Cpp.default.configuration": "C:/myProject/.vscode/c_cpp_properties.json"

这将告诉VS Code使用C:/myProject/.vscode/c_cpp_properties.json文件来配置C++项目。
然后在项目目录中创建c_cpp_properties.json文件，使用以下格式进行配置：

{
"configurations": [
{
"name": "Win32",
"intelliSenseMode": "${default}",
"includePath": [
"${workspaceFolder}",
"C:/Program Files (x86)/Microsoft Visual Studio/2019/Community/VC/Tools/MSVC/14.22.27905/include",
"C:/Program Files (x86)/Windows Kits/10/Include/10.0.18362.0/shared",
"C:/Program Files (x86)/Windows Kits/10/Include/10.0.18362.0/ucrt"
],
"browse": {
"limitSymbolsToIncludedHeaders": true,
"databaseFilename": "${workspaceFolder}/.vscode/browse.VC.db"
}
}
],
"version": 4
}

解释一下以下几个字段的含义：
“name”：配置名称，表示这是一个用于Windows平台的配置项。
“intelliSenseMode”：智能感知模式，使用${default}表示使用默认设置。
“includePath”：头文件搜索路径，包含了包括当前项目所在目录、编译器包含目录等所有路径。
“browse”：自动完成和智能提示的索引信息。
根据自己的项目需要调整配置。

三、配置示例

配置应用范例

下面是一个配置文件的例子，它用于一个使用了Qt框架的C++项目：

{
"configurations": [
{
"name": "Win32",
"includePath": [
"${workspaceFolder}",
"${workspaceFolder}/src",
"${workspaceFolder}/include",
"C:/Qt/Qt5.8.0/5.8/msvc2015_64/include",
"C:/Qt/Qt5.8.0/5.8/msvc2015_64/include/QtCore",
"C:/Qt/Qt5.8.0/5.8/msvc2015_64/include/QtGui",
"C:/Qt/Qt5.8.0/5.8/msvc2015_64/include/QtWidgets"
],
"defines": [
"_DEBUG",
"UNICODE",
"_UNICODE"
],
"browse": {
"path": [
"${workspaceFolder}",
"C:/Qt/Qt5.8.0/5.8/msvc2015_64/include",
],
"limitSymbolsToIncludedHeaders": true,
"databaseFilename": "${workspaceFolder}/.vscode/browse.VC.db"
},
"intelliSenseMode": "${default}",
"compilerPath": "C:/Qt/Qt5.8.0/5.8/msvc2015_64/bin/cl.exe",
"cStandard": "c11",
"cppStandard": "c++17"
}
],
"version": 4
}

配置库范例

下面是一个配置文件的例子，它用于一个使用了小型三方库POCO的C++项目：

{
"configurations": [
{
"name": "Win32-Debug",
"includePath": [
"${workspaceFolder}",
"${workspaceFolder}/src",
"${workspaceFolder}/include",
"C:/Program Files (x86)/Microsoft Visual Studio/2019/Community/VC/Tools/MSVC/14.22.27905/include",
"C:/Program Files (x86)/Windows Kits/10/Include/10.0.18362.0/shared",
"C:/Program Files (x86)/Windows Kits/10/Include/10.0.18362.0/ucrt",
"C:/Program Files (x86)/POCO/include",
"C:/Program Files (x86)/POCO/include/Poco",
"C:/Users/user/Documents/mysql-connector-c++-8.0.26-winx64/include"
],
"defines": [
"POCO_NO_UNWINDOWS",
"POCO_WIN32_UTF8",
"_WIN32_WINNT=0x0601"
],
"browse": {
"path": [
"${workspaceFolder}",
"C:/Program Files (x86)/POCO/include",
"C:/Program Files (x86)/POCO/include/Poco",
"C:/Program Files (x86)/mysql-connector-c++-8.0.26-winx64/include"
],
"limitSymbolsToIncludedHeaders": true,
"databaseFilename": "${workspaceFolder}/.vscode/browse.VC.db"
},
"intelliSenseMode": "${default}",
"compilerPath": "C:/Program Files (x86)/Microsoft Visual Studio/2019/Community/VC/Tools/MSVC/14.22.27905/bin/Hostx86/x86/cl.exe",
"cStandard": "c11",
"cppStandard": "c++17"
}
],
"version": 4
}
