Very complicated and designated message, looks like you are missing .o file for standard Nios II component.

You can check the system library of your Nios II project, if missing specific file I will suggest reinstallation.

Where is this nios_jumptostart.s supposed to come from? If it's yours, try changing the .s to .S (capital S).
