clangd 需要 compile_commands.json 提供补全和跳转支持

CMake 工程生成 compile_commands.json

cmake -DCMAKE_EXPORT_COMPILE_COMMANDS=1
# or add to CMakeLists.txt
set(CMAKE_EXPORT_COMPILE_COMMANDS ON)

Makefile 工程生成 compile_commands.json

brew install bear
bear cmd # Eg: bear make

clangd 指定 compile_commands.json 位置

clangd --compile-commands-dir=${workspaceFolder}/build/

Clangd config file

project configuration: a file named .clangd in the source tree. (clangd searches in all parent directories of the active file) Generally this should be used for shared and checked-in settings. (Existing directories named .clangd can be deleted. These were used for temporary storage by clangd before version 11.)

user configuration: a config.yaml file in an OS-specific directory:

Windows: %LocalAppData%\clangd\config.yaml, typically C:\Users\Bob\AppData\Local\clangd\config.yaml. macOS: ~/Library/Preferences/clangd/config.yaml Linux and others: $XDG_CONFIG_HOME/clangd/config.yaml, typically ~/.config/clangd/config.yaml. Private settings go here, and can be scoped to projects using If conditions.

Each file can contain multiple fragments separated by --- lines. (This is only useful if the fragments have different If conditions). JSON is a subset of YAML, so you can use that syntax if you prefer. Changes should take effect immediately as you continue to edit code.
