I installed ncurses from the .pkg installer from this site on my Mac G4 running OSX 10.1 earlier this month. The install went off without a hitch (or a complaint worthy of the installer bringing to my attention, at least).

However, whenever I attempted to compile a program using the ncurses library and header, I would get several "unused multiple definitions" of the standard curses functions.

These were only warnings of course, and the program would compile fine otherwise. Whenever I would run the program, the ncurses color functions would refuse to take effect. I WAS able to use the wattron and wattroff functions to display chararcters in blink, bold, underline, and other modes.

I am still getting multiple definition warnings when I link a program with the -lncurses library. I've checked through the list, and it includes each of the standard curses functions and none of the new ncurses functions--possibly the old curses header is getting included along with the ncurses one somehow?

The linker warnings are as follows:

I wrote up a quick test program that printed the result of can_change_color(), and it appropriately returns FALSE. Me wants color! You help please!

I also removed the old curses.h header from the include directory and put it someplace safe, but I still recieve multiple unused symbols warnings when linking. It doesn't seem like this could be related to the color problem, but it baffles me nonetheless.
