Also, this wonderful page too: http://compilers.iecc.com/crenshaw/
It exactly what you're looking for. No automated tool, library etc; In fact, you will need to have a automated tool: the Pascal compiler for compile your compiler. But I guess it is not a problem, right? :p the tutorial is really nice I’m at tutor6 right now and the guy really teaches step-by-step each little thing about we are going to working on. The toturial is unfinished but don’t worry, you can learn a lot with the contents he has provided so far. (sorry english, not my native language)
Mr. Bright, you're my hero. Really. Not only because you have made a C++ compiler using recusive descent parser and it's was the first ever to generate native code and the first comercial too and you don't even do generate assembly on dmd. You still made the D language and dmd compiler. A world saving tool from C and C++. It will rock the world. Could you imagine one of the next world's famous software like Windows or *BSD written in D? Also, I'm on the way on compiler business too (joke :-)). (sorry english, not my native language)
