Comme prevu, je ne sais pas compiler

Voila ce que j'ai fait en gros :

vi /home/debuser/force_eject.cc

j'ai collé ca dedans :

#include <sys/ioctl.h>

int main(void){
int fd = -1;
fd = open("/dev/cdrom", O_RDONLY|O_NONBLOCK, 0);
if (fd > 0) {
ioctl(fd, CDROM_LOCKDOOR, 0);
close(fd);
}
fd = open("/dev/cdrom", O_RDONLY|O_NONBLOCK, 0);
if (fd > 0) {
ioctl(fd, CDROMEJECT, 0);
close(fd);
}
}

Je quitte et je sauve
:wq

Et je lance la compilation :

cc /home/debuser/force_eject.cc -o /home/debuser/force_eject

Et la mon PC me rote au visage :

/home/debuser/force_eject.cc: Dans function « int main() »:
/home/debuser/force_eject.cc:5: error: `O_RDONLY' undeclared (first use this
function)
/home/debuser/force_eject.cc:5: error: (Each undeclared identifier is reported
only once for each function it appears in.)

function)
/home/debuser/force_eject.cc:12: error: `CDROMEJECT' undeclared (first use this

Si vous pouviez me détailler en détails ce que je dois faire. svp

Merci encore
