I've just discovered ncurses and have just started learning it, however the examples in my tutorial don't compile on my computer.
I had to install ncurses manually and did so by entering "apt-get install libncurses5-dev libncursesw5-dev". I had to do this because before having done so I got an error saying that I could not "#include ".
Installing it worked, but now I get this error instead:
touzen@comp:~/learning_ncurses$ g++ -o hello_world hello_world.cpp
/tmp/ccubZbvK.o: In function `main':
hello_world.cpp:(.text+0xa): undefined reference to `initscr'
hello_world.cpp:(.text+0x16): undefined reference to `printw'
hello_world.cpp:(.text+0x1b): undefined reference to `refresh'
hello_world.cpp:(.text+0x20): undefined reference to `stdscr'
hello_world.cpp:(.text+0x28): undefined reference to `wgetch'
hello_world.cpp:(.text+0x2d): undefined reference to `endwin'
collect2: ld returned 1 exit status
The code I compiled looks like this:
#include <ncurses.h>
int main(){
initscr();
printw("Hai thar world...");
refresh();
getch();
endwin();
return 0;
}
Why do I get this error. And even more importantly, how do I fix this?
you have to link the ncurses library
g++ -o hello_world hello_world.cpp -lncurses
