I just extracted the curses-clock.shar archive from comp.unix.questions, and it gave me an error that certain symboks were undefined, as below. Fine, I said, I will just use -ltermcap or -lcurses, but neither worked. Can anyone tell me in what library these symbols are defined? I am using a Sun 3/260 running SunOS 4.0.3.

By the way, -lwhatever is NOT a command line option; it's shorthand for a library file name and thus should be placed after the .o names.

There seems to be a trend for vendors of UNIX to drop support for /etc/termcap, in favour of termlib. If this is the case with your Sun, you might try using the terminfo library anyway, since some of the termcap functions are emulated using terminfo calls. This support might be withdrawn in future too. This wasn't a solution for us, because we extended the termcap we use to add things like box drawing elements and other video attributes. Finally, we found some Public Domain emulations of tgetent et.al., which I will be happy to share if there are enough requests. I'd rather not mail them, since we have to pay quite a bit for all mail coming into and out of NZ.
