Compiling Error

Hello, I’m helping get a Rostock Max V2 3D printer back up and running. This printer runs off of an Arduino board, which I’m not familiar with at all. The instruction manual had me compile and upload a bunch of things to the printer, which it had no problems with, except for this file. When I tried to upload it, I got the following error:

sketch\Eeprom.h:452:5: internal compiler error: Segmentation fault

}

Please notify me with any possible solutions, thanks!

This bug is specific to the 5.4.0-atmel3.6.1-arduino2 version of avr-gcc used by Arduino AVR Boards 1.6.22 and newer. It has been reported here:

Here's the traditional workaround:

  • Tools > Board > Boards Manager
  • Wait for downloads to finish.
  • When you move the mouse pointer over "Arduino AVR Boards", you will see a "Select version" dropdown menu appear. Select "1.6.21".
  • Click "Install".
  • Wait for installation to finish.
  • Click "Close".

If you have File > Preferences > Check for updates on startup checked, the Arduino IDE may occasionally notify you that a new version of Arduino AVR Boards is available, you'll need to refrain from updating back to the new Arduino AVR Boards version, otherwise you'll be back to seeing the segmentation fault error again.
