How to document errormessages?

New to Arduino I cannot find any way to print/document messages appearing in looging window during compiling.

I appreciate any advice.

Thanks!

Windows 7:
in your appdata\local\temp\ (?) there will be a folder made (consolexxxxxxxxxxx ) with two text files stderr.txt and stdout.txt

other platforms - check temp folders.

Click the “logging window” to give it the focus. Press Ctrl+A to select all. Press Ctrl+C to copy.

You can now do what you’d like with the text.

In Ubuntu, Ctrl-c does not work when copying from the Arduino IDE to another window, but it does work inside a terminal window. So if you start the arduino software from a terminal all the log messages will be displayed int the terminal windows. You can copy/paste from the terminal window.
