vscode设置C++调试功能

安装如下插件clang-format、CMake、CMake Tools，设置好C_Cpp: Clang_format_path

vscode 工程 #include <opencv2/opencv.hpp> 下有波浪线

• 使用Cmakelist.txt检索文件

cmake_minimum_required(VERSION 3.10)
project(test)

set(CMAKE_CXX_STANDARD 11)
set(CMAKE_CXX_FLAGS  "${CMAKE_CXX_FLAGS} -g")

set(OpenCV_DIR /home/ly/Public/opencv-4.5.5/lib/cmake/opencv4)
find_package(OpenCV REQUIRED)

add_executable(${PROJECT_NAME} main.cpp)
target_link_libraries(${PROJECT_NAME}  ${OpenCV_LIBS})

• 按F5 生成c_cpp_properties.json、launch.json，该文件在.vscode目录下
• c_cpp_properties.json:

{
    "configurations": [
        {
            "name": "Linux",
            "includePath": [
                "${workspaceFolder}/**"
            ],
            "defines": [],
            "compilerPath": "/usr/bin/gcc",
            "cStandard": "gnu17",
            "cppStandard": "gnu++14",
            "intelliSenseMode": "linux-gcc-x64",
            "configurationProvider": "ms-vscode.cmake-tools"
        }
    ],
    "version": 4
}

launch.json:

// Use IntelliSense to learn about possible attributes.
// Hover to view descriptions of existing attributes.

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "(gdb) 启动",
            "type": "cppdbg",
            "request": "launch",
            "program": "${workspaceFolder}/build/ldmk_blink",
            "args": [
                "--face=/home/ly/Projects/face-alg-mnn/model/face/version-RFB/RFB-320.mnn",
                "--landmark=/home/ly/Projects/face-alg-mnn/model/landmark/slim_160_latest.mnn"
            ],
            "stopAtEntry": false,
            "cwd": "${workspaceFolder}",
            "environment": [],
            "externalConsole": false,
            "MIMode": "gdb",
            "miDebuggerPath": "/usr/bin/gdb",
            "setupCommands": [
                {
                    "description": "为 gdb 启用整齐打印",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": true
                }
            ],
            //"preLaunchTask": "C/C++: g++.exe build active file"
        }
    ]
}

• 如果还是有问题，关闭重新打开

vscode C++ 语言格式

• 首先 preference --> setting，搜索clang，设置如下
  
• 安装clang-format sudo apt install clang-format
• 在工程根目录设置.clang-format文件，内容如下：

# 语言: None, Cpp, Java, JavaScript, ObjC, Proto, TableGen, TextProto
Language: Cpp

# 基于某一主题上的修改

# 缩进宽度
IndentWidth: 4

# 缩进case标签
IndentCaseLabels: false

# 访问说明符(public、private等)的偏移
AccessModifierOffset: -4

# 每行字符的限制，0表示没有限制
ColumnLimit: 0

# 对齐连续的尾随的注释
AlignTrailingComments: true

# 允许函数声明的所有参数在放在下一行
AllowAllParametersOfDeclarationOnNextLine: false
# 允许短的if语句保持在同一行
AllowShortIfStatementsOnASingleLine: false
# 允许短的case标签放在同一行
AllowShortCaseLabelsOnASingleLine: true
# 允许短的循环保持在同一行
AllowShortLoopsOnASingleLine: false

# 允许排序#include
SortIncludes: true
