unsatisfied forward or external declaration

Question

getting an error while compiling .pas file "unsatisfied forward or external declaration :TxxxException.CheckSchemeFinMethodDAException." any idea what this error could imply? Does it mean that "CheckSchemeFinMethodDAException" was not called in all the concerned files?

Answer 1

You have declared this method but didn't implement it.

Answer 2

unit Unit1;

interface

type
  TMyClass = class
    procedure DeclaredProcedure;
  end;

implementation

end.

This yields the error you describe. The procedure DeclaredProcedure is declared (signature) but not defined (implementation part is empty).

You have to provide an implementation for the procedure.
