Problems with clangd in vscode

Included files not found

Try set(CMAKE_EXPORT_COMPILE_COMMANDS ON) in your CMakeLists.txt
Then reconfigure with CMake

STD headers not found when cross compiling with devkitpro

I'm cross compiling my c++ project to the Nintendo DS with CMake but clangd won't find all the standard header files.
Creating the following settings.json in .vscode solved my problem.
Replace <Path/to/devkitpro> with your actual devkitpro installation

{
    "clangd.arguments": [
        "--query-driver=<Path/to/devkitpro>/devkitARM/bin/arm-none-eabi*",
        "--compile-commands-dir=${workspaceFolder}/build"
    ]
}
