File lcd.c : avr/io.h: and util/delay.h No such file or directory

[madarain10]

Could you advise something about avr/io.h: and util/delay.h

You have to set up your build environment correctly so that the include files (the ones you say "no such file") are visible to the include path. If you are using an AVR setup, these should have been installed. See if they are installed on your system, and if so if the (avr) compiler finds a path to them.
