VsCode+Clangd+SSH+CMake

安装

Linux上安装Clangd，CMake
安装VsCode，安装VsCode插件clangd， ssh， CMake

配置

1.VsCode的Clangd插件配置Linux上的Clangd路径。

2.VsCode配置Clangd功能

cpp 复制代码

{
    // clangd 补全 
    "editor.formatOnPaste": true,
    "editor.formatOnType": true,
    "C_Cpp.errorSquiggles": "Disabled",
    "C_Cpp.intelliSenseEngineFallback": "Disabled",
    "C_Cpp.intelliSenseEngine": "Disabled",
    "clangd.path": "/usr/bin/clangd",
    "clangd.arguments": [
        "--compile-commands-dir=${workspaceFolder}/build",
        "--query-driver=/home/ljx/workspace/tools/xxx/bin/*",
        "--enable-config",
        "--log=verbose",
        "--pretty",
        "--all-scopes-completion",
        "--completion-style=bundled",
        "--cross-file-rename",
        "--header-insertion=iwyu",
        "--header-insertion-decorators",
        "--background-index",
        "--clang-tidy",
        "-j=2",
        "--pch-storage=disk",
        "--function-arg-placeholders=false",
        "--compile-commands-dir=build"
    ],

    "clangd.fallbackFlags": [
        "-pedantic",
        "-Wall",
        "-Wextra",
        "-Wcast-align",
        "-Wdouble-promotion",
        "-Wformat=2",
        "-Wimplicit-fallthrough",
        "-Wmisleading-indentation",
        "-Wnon-virtual-dtor",
        "-Wnull-dereference",
        "-Wold-style-cast",
        "-Woverloaded-virtual",
        "-Wpedantic",
        "-Wshadow",
        "-Wunused",
        "-pthread",
        "-fuse-ld=lld",
        "-fsanitize=address",
        "-fsanitize=undefined",
        "-stdlib=libc++",
        "-std=c++17"
    ],
}

3.Linux上 ~/config/clangd/config.yaml配置忽略语法

bash 复制代码

CompileFlags:
  Add: -Wno-unknown-warning-option
  Remove: [-march=*, -mabi=*, -f*, -V*, ]

Diagnostics:
  Suppress: ['drv_unknown_argument', 'unused-includes', 'pp_file_not_found', 'drv_unsupported_opt', ]

4.CMake添加生成COMPILE_COMMANDS文件

cpp 复制代码

set(CMAKE_EXPORT_COMPILE_COMMANDS ON)

或者编译时添加配置
