That's not helpful. We need the FULL error output. If you scroll the black console window at the bottom of the Arduino IDE window up you will see there is much more. When you encounter an error you will see a button on the right side of the orange bar "Copy error messages". Click that button and then paste the error message in a reply here USING CODE TAGS(</> button on the toolbar).
