First, you should understand [How kernel, compiler, and C library work together]. If any of the next steps gives you trouble, the information given in that document should give you an idea of what is missing.

Next, you should build a [GCC Cross-Compiler] for your platform.

Then, you need a C standard library for your platform - at least those parts required by GCC.

Finally, you would use the cross-compiler to compile [GCC] ''to run on your platform''.

Just to be sure, you would use that "native" [GCC] to compile itself (to be sure it could, and for weeding out any issues that might arise from cross-compilation). Congratulations, you are now what people call "self-hosted", i.e. you no longer need some other OS to do development work. (Provided you have a working editor for your platform.)
