Compiler

Hey guys, I am set to start on OS project from scratch.
My question is should I build a compiler or I can use an existing one?
I mean the OS will be in assembly language form when compiled, so why should I build a compiler.
Hope I explained my concern correctly.

A compiler for a new language (or an old one) is a pretty big project; probably equal or greater in magnitude than a whole OS. If you're just starting out, I'd highly recommend writing your OS using an existing language toolchain like C/GCC. Once you're more experienced, you can try doing language development and OS development at the same time.

I wouldn't recommend trying to write a compiler (one thing at a time, please), but you almost certainly want to build a cross-compiler. See the Wiki for details.

This is an illogical sentence, like "If soup is good for you, why use toilet paper?" How does it follow that you should or shouldn't build a compiler from the target language (i.e., assembly) of the compiler(s) you will use?
