how to compile c code so it can run without os.

Question

we need different compilers for same c code for linux and windows because they have different ABI. Now what if i want to make my own OS or BIOS which will run without any OS(and ABI). Which compiler will i use. And how it all will work.

Answer 1

wow. difficult one. i would say you would have to write your own compiler made exclusively for your own os.
