vscode阅读Linux代码(clangd)

vscode阅读Linux代码(clangd)

Linux主机配置

sudo apt install clangd bear

编译内核代码，并生成编译信息文件

make ARCH=arm64 orangepi-zero3_defconfig
make ARCH=arm64 CROSS_COMPILE=/work/orange_zero_3/buildroot/output/host/bin/aarch64-linux- -j12

或者在make前面添加命令：bear --append -- ,下步骤可以不做

生成compile_commands.json

python3 ./scripts/clang-tools/gen_compile_commands.py

vscode配置

禁用或卸载官方C/C++插件

安装插件：clangd，LLDB DAP，CMake Tools

全局配置（局部配置需要手动创建json文件），如需使用，仅需复制clangd部分即可。

    ],
}

配置clangd

设置—>搜索clangd—>Clangd: Arguments—>添加项

--compile-commands-dir=${workspaceFolder}

删除配置（否则会报Clang Language Server client: couldn’t create connection to server.）

--compile-commands-dir=build

创建.clangd文件（源码目录下面）

解决error: invalid AST错误，此处是照抄别人的配置，具体含义未知。

CompileFlags:       
  Remove: -mabi=lp64
