It's 2023. If you're not using an IDE or a highly extensible text editor with simple static analysis features, I really don't know what to tell you.

Clang won’t tell you if you’re missing a return statement, even with all warnings on and will just let it crash during runtime. Static analysis won’t save you from all stupid mistakes.

Is this C++? Have you got some code examples?

I’ve been writing C++ for 20+ years and the last compiler I encountered this with was Borland’s. In the late 90s.

It's on the company computer, but I have a backup from earlier today that seems to have the same code.

bool load_metadata() {
    uint8_t marker_field = EEPROM.read(0);
    // Write to ROM if marker has not been set
    if (marker_field != MARKER) {
        metadata = {
            0,
        };
        EEPROM.put(1, metadata);
        EEPROM.update(0, MARKER);
    }
    else {
        EEPROM.get(1, metadata);
    }
}

I have to admit, my experience with C++ is rather limited, last Monday was the first time in my life that I used a C++ compiler. I had some issues getting it to work with Visual Studio, so I ended up using VS Code WSL with clang 😅.

Does this compile with -Wall -Werror? (might not be an option if your dependencies’ headers contain warnings)

Looks like it may be embedded code for a SoC or similar. The only things I can think of is that the tool chain you’re using maybe non-standard… or you’re invoking the dreaded Undefined Behaviour somewhere :(

I didn’t use -Werror but no warning about it showed up either. The project uses a semi-custom toolchain for a microcontroller, but I’m not using it to compile this code. I have another file with an entrypoint which tests some classes to be used by the microcontroller. The EEPROM in the code example is actually a macro for a class I’ve written that emulates the EEPROM library by writing and reading to a file on disk.

It’s a bit of a mess but this dual toolchain setup seemed easier than emulating the board and peripherals in it’s entirety. I might have to retry that though using Wokwi.
