Requirements

Compilation Database

In order to make this plugin work effectively, clangd requires information about how your code should be compiled. There are two options: compile_commands.json, or compile_flags.txt.

compile_commands.json

CMake is currently your best bet for generating a compile_commands.json file. The command to generate compile_commands.json along with your project looks something like this: cmake (SOURCE_DIR) -DCMAKE_EXPORT_COMPILE_COMMANDS=ON

CMake doesn't include header information in the compile_commands.json file. To rectify this, I use a tool called compdb.

Clangd won't see your compile_commands.json file if it's placed in your build directory, so you should either symlink it to your project directory, or have compdb generate its output there.

compile_flags.txt

Another supported solution is to make a compile_flags.txt file and place it in your project directory. Clangd will treat all project files with the same options. A simple compile_flags.txt might look something like this:

-std=c++11
-Iinclude
-DMY_DEBUG_FLAG
