I would love to use golang for this but it’s standard library alone is bigger than the amount of available RAM.

Interesting, since golang only includes the parts of the stdlib that are used in the executable binary.

I just tested it and a simple hello world program still produces a 1.7MiB binary, while the device only has 512KiB of RAM.

package main

import "fmt"

func main() {
    fmt.Println("hello world")
}

Strip the debug info, should be a lot smaller. Also check out TinyGo, it's meant for embedded devices

BTW: what are you using instead to get small binaries/scripts?

Likely your C++ implementation also doesn't ship the full standard library. And you may even turn off exceptions and RTTI.
