"pins_arduino.h: no such file or directory", but it's there?

Hi, so, I'm fairly new to Arduino (but I've gobbled up all info I could find) and I'm having trouble.

I'm doing a project that involves ATmega168s on a protoboard. I followed the tutorial (barebones), and downloaded the files and placed them in the right directories. But when I open the program and select ATmega 328 on a breadboard (8mhz) and load the blink sketch to compile it says:

"arduino-1.0.1\hardware\arduino\cores\arduino/Arduino.h:213:26: error: pins_arduino.h: no such file or directory"

Does anyone know the problem?

I followed the tutorial (barebones)

I do believe that there is more than one. Which one are you referring to?

downloaded the files

Which files? From where?

and placed them in the right directories.

Which ones would those be?

But when I open the program

Which program?

Sorry for not clarifying.

The tutorial: http://www.arduino.cc/en/Tutorial/ArduinoToBreadboard

The files included in the “Minimal Circuit(Removing the External Clock)” section. I downloaded that zip.

I then placed it in the proper file directory: the “Hardware” subdirectory.

The program being Arduino.exe, the program for programming the Arduino and uploading code.

Are you finding the "ATmega328 on a breadboard (8 MHz internal clock)" under >Tools>Board>?

If not, here is the path that it should be: C:\Users[youruserprofilehere](My) Documents\Arduino\hardware\breadboard\boards.txt

Yes, I am finding it under the tools>boards menu.


What version of the IDE are you running?

I'm using Arduino 1.0.1

Try adding this line at the end of the boards.txt file:


Or if that doesn't work, try this one:
