Um. Compile with what? Yes, after you have a compiler, you can use it to
compile the compiler. Boostrapping cam be decidedly non-trivial. THat's
the whole point, which it looks like you missed.

Not that I've done much of that kind of thing myself, but I'd think a
common way would be to start by making use of cross compilation. That
sure beats starting from scratch. Something I have done is "boostrap" by
using other (possibly older" compilers. But that requires a pre-existing
compiler of some kind or other, and if you are posrting a new one
because of shortcommings in the existing ones, it might be non-trivial
to get the new one to compile with the old one.
