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.

Could it be possible that I need to install X-Windows for color to work? Has anyone else tried installing ncurses, and run into problems? I'd like to put this behind me so I can decide whether to continue my little "project" on the Mac, or just fall back to my PC running FreeBSD.

The non-color issue was solved simply by installing Eterm in place of my xterm and my other shells. As I far as that goes, I now have 2 of 3 problems solved...

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:

code:

I take that back, color isn't working in Eterm either...

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.

I also have one last question... is there any way I can get a font with the PC-style extended ASCII characters? I was hoping I could use the tees, blocks, and so on, but my Mac fonts all have accented letters in place of them.

if running mac os x 10.2+ or darwin 6.0+, ncurses should already be installed no?

Nay, I'm running 10.1 since I was a bit reluctant to spend $130 more to upgrade to 10.2--all I have is the lame curses library Apple included. Would it really be worth it to pay $130 for ncurses and gcc3 (gcc3 which I already have)?

Long lag here, but I presume nobody found the answer for color... which is setenv TERM ansi at least on Jag.
