I'm writing a program for a fancontroller. I'm in a very early stage of the program (only defined some variables, pins and EEPROM memory locations and written a simple get-values-out-of-EEPROM fucntion) but wanted to check for syntax errors. Weirdly, the compiler gave me two errors: "undefined reference to 'setup'" and 'undefined reference to 'loop'". Does anyone know what this means and how I can fix it?
