an error with curses.h library in gcc

[asixbabak]

hi there

i am new to this forum

i am working on a course project,it is simplified Pacman .

i used to get "char"s from input w/o pushing enter button , in windows compilers there is a library named conio.h but it is not standard
so i installed a similar(maybe!) library curses.h
using this command:

sudo apt-get install libncurses5

and i included to my c++ code:

...
#include<curses.h>

...

int loop()
{
char a;
a=getch();
cout<<a<<endl;
...

and I get two errors:
undefined reference to 'stdscr'
undefined reference to 'stdscrwgetch'

what should I do?

have you linked with libcurses?

g++ -lcurses
or -lncurses if you use ncurses instead of curses

[mchecca]

Do you have the development package installed?

sudo apt-get install libncurses5-dev

"This package contains the header files, static libraries
and symbolic links that developers using ncurses will need."

[asixbabak]

yes
i have installed curses precisely
but still got the problem

[MadCow108]

are you sure you need stdscrwgetch?
as far as I can tell this function does not exist with this name in curses.

getch gets translated to: wgetch(stdscr) on my system
both these symbols exist in libcurses.

nm --dynamic /usr/lib/libncurses.so  | grep -E "wgetch|stdscr"
0000000000243db0 B stdscr
0000000000016d40 T wgetch

maybe a typo?
