So in sdStringTable
line 75:
TsdStringTable = class(TsdDebugComponent)
error "undeclared identifier TsdDebugComponent"

This component is in sdDubug, which should be included as on line 46 there is the uses clause with sdDebug unit:
uses
Classes, SysUtils, Contnrs, sdDebug;

sdDebug contains it on line 86.
