help with getch()

[vhg119]

i included curses.h as well as stdlib.h and stdio.h in my lil program

the main function only contains 3 lines

int number;
number = getch();
printf( "you typed %c", number);


when i compile this, gcc gives me some errors:
cursestest.c:9: undefined reference to 'stdscr'
cursestest.c:9: undefined reference to 'wgetch"

what is the problem?

did you compile with -lncurses?

gcc program.c -lncurses

[Energon]

Add -lcurses to your compile line. So something like this:

# gcc -Wall -c cursestest.c
# gcc -o my_program -lcurses

That'll make it link to the curses libraries. You may need to specify where those libraries are at if it doesn't work, which would look like:

# gcc -o my_program -L/path/to/curses/lib -lcurses

doh!
now it gives me:
undefined references to 'main'

hey i got it!

i thought i could just use getch() by itself. But i needed to create a WINDOW type pointer and initiating a window and everything... kinda like gtk programming i guest.

thanks guys.. that gcc argument thing helped too. :D

there are some ncurses examples at:
CCAE (http://www.codeexamples.org)

Check out how to use select. Using ncurses for the functionality of getch is a bit superfluous.

[vhg119]

select? i'll look into that.
are there any good howto's and documentation? kinda like the gtk+ one on gtk.org?

man select :)

(yes, it has an example)
