Resolving stdio.h and FPU Instruction Errors in STM32F103 Project with clangd and Neovim

@Sterling For stdio.h not found, add the ARM toolchain include path to compile_commands.json:

{
    "directory": "/path/to/project",
    "command": "arm-none-eabi-gcc -I/path/to/arm-none-eabi/include -o file.o -c file.c",
    "file": "file.c"
}

{
    "directory": "/path/to/project",
    "command": "arm-none-eabi-gcc -I/path/to/arm-none-eabi/include -o file.o -c file.c",
    "file": "file.c"
}

For FPU instructions, ensure the target CPU is specified:

{
    "directory": "/path/to/project",
    "command": "arm-none-eabi-gcc -mcpu=cortex-m3 -mthumb -o file.o -c file.c",
    "file": "file.c"
}

{
    "directory": "/path/to/project",
    "command": "arm-none-eabi-gcc -mcpu=cortex-m3 -mthumb -o file.o -c file.c",
    "file": "file.c"
}

Update your Makefile:

MCU = -mcpu=cortex-m3 -mthumb

MCU = -mcpu=cortex-m3 -mthumb

Alternatively, try installing ccls as an LSP:

sudo apt install ccls

sudo apt install ccls

Then configure Neovim to use ccls.
