write code vhdl cruise control how ???

have error :confused: why

(Error (10481): VHDL Use Clause error at cruise_control.vhd(3): design library "work" does not contain primary unit "my_components")

(Error (10800): VHDL error at cruise_control.vhd(3): selected name in use clause is not an expanded name)
