/dev/lirc0 does not exist

Question

I want to use an IR diod receiver. I installed lirc but when I write to terminal this code:

mode2 -d /dev/lirc0

it says

mode2: could not get file information for /dev/lirc0
mode2: defauld_init(): No such file or directory

Where is the problem? Any idea?

It may be because of device tree. See raspberrypi.stackexchange.com/questions/27073/… — joan, Commented May 13, 2015 at 8:56
thank you for your answer. It works, and I record my remote but now I'm writing "irw" but it doesn't show any thing about my buttons. — Muhammed Ali HAŞILOĞLU, Commented May 18, 2015 at 8:40
I think you should open a new question giving the details of the new problem. — joan, Commented May 18, 2015 at 8:56

It means there is a configuration issue.

To fix it:

sudo vim /boot/config.txt
add dtoverlay=lirc-rpi,gpio_in_pin=16 (change the pin to whatever you're using)
reboot

The tutorial I was following left this crucial step off.
