compiler problem - curses.h

compiler problem - curses.h

[Reed Sekiya]

	I've been having problems compiling a program that includes
curses.h to maintain inventory.  "gcc inventory.c" results in undefined
symbols.  I've tried compiling it on several different versions of
unix.  I've tried everything that I could think of.  Can someone please
help me get over this problem?  The various error reports on the different
version of unix are:

Re: compiler problem - curses.h

[bjorn rohde jensen]

Hi Reed,

  Are you really only including the library
header and not linking with the library
itself? You are lacking a -lcurses option
to gcc in the two listed cases for sure.

Yours sincerely,

Bjorn
