In the name of simplicity, Duke CS doesn't cover some of those things until very late in the game. Like, say, next semester :-) Their (our?) philosophy is that it is more motivational to write code first and then figure out how exactly the background stuff works later. I suppose it works OK, as long as you don't intend to do anything outside of class. > Ok, it is the C-library (libc.a) with the startup routine (crt0.o) and > perhaps yet something else. No library and startup files -- no executables... Thanks, Kai. That would explain why it works, despite the error message. I don't know if any of you are aware, but the new Lego Mindstorms robotics kit uses a hitachi chip. Due to the limitations of the standard Lego software, Markus Noga (http://www.multimania.com/legos/.) wrote an "OS" for it, to be compiled with egcs/gcc, which has an abridged standard C library. Very abridged. malloc, calloc, and free. For the purposes of the legOS, that's all that's necessary. Anyway, thanks for the explanation. I appreciate the help.
