Greetings,

#include

int main()

  initsscr();
  cbreak();
  noecho();
  char x = getch();
  while(x != 'q')
  {
printf("Entered: %c\n",x);
x = getch();
  }
  endwin();
}

And I compile using

gcc -lncurses ctest.c

When linking I get an undefined reference for each curses function.
I'm sure I'm doing something wrong.


Try:
gcc ctest.c -lncurses

Try: gcc -o test ctest.c -lncurses

The program doesn't do anything until 'q' is typed...

Classic newbie mistake.  Libraries should follow source/object files on
the gcc command line.  "gcc ctest.c -lncurses" should work.  Not
Cygwin-specific.
HTH,
