I just wrote a little test program to see if I could apply
anything I learned in CS 161 to a real life compiler. Everything
we've done so far has been in CodeWarrior, a crappy Mac IDE.

Anyway,

I made a Test class, which did a little cin, and a little cout.
It compiles with no errors/warnings. Upon execution, I get

/usr/libexec/ld.so: Undefined symbol "_tgetstr" in testprog:
/usr/lib/libcurses.so.2.1

I've #includ <iostream.h>

what am I missing?

I'm running NetBSD 1.2 hp300. This compiles fine and executes 
beautyfully under Linux. (Its probably a config problem).

Thanx
