Can't write to stdscr

When I today began learning ncurses API, I ran into a problem. I can't write into stdscr.
I wrote few short programs, but none of them did work. I tried to write with printw(), mvprintw(), addch() and mvaddch() functions, but they didn't work. I tried to also write with printf() function in ncurses mode, but nothing happent. Writing with printf() while not in ncurses mode works fine.
Version of ncurses library I'm using is 5.6. OS I'm using is Xubuntu GNU/Linux. Terminal emulator is Xfce-Terminal. Comipler is gcc 4.1.2. If someone needs more information, I can tell, or if I don't know, try to find out it.

Probably ncurses closes all funny file descriptors, including stdscr, whatever that is. Just use stdout.

Do basic ncurses programs work for you?
http://tldp.org/HOWTO/NCURSES-Programming-HOWTO/

Have you called initscr() ? Are you calling refresh() ? Could you post a minimal not-working example?

Salem: No, they don't work.
Cactus_Hugger: Yes, I have called initscr() and refreshed window after printing.
And one minimal example:

Code:

---

/* Hello, World */

#include <ncurses.h>

int main(void) {
    initscr();

    printw("Hello, World!");
    refresh();

    endwin();
    return 0;
}

fronty, got the ncurses library installed (ie not just ncurses-devel)

I compiled only source package I found for version 5.6, so I think I have whole library installed. :/

Your minimal sample may be running too quickly. Place a getch() right before the endwin() call.

:/ Doesn't work. :/
It seems to me it writes to it, but somehow it doesn't show it on teminal.

IIRC, there are a multitude of different terminal emulators on most Linux distros.
Have you tried other ones?

Tried with xterm, and with it works. Must try to find out why it didn't work with Xfce-terminal.
