Delphi Compiler Error
E2086 Type ‘%s’ is not yet completely defined
Reason for the Error & Solution
This error occurs if there is either a reference to a type that is just being defined, or if there is a forward declared class type in a type section and no final declaration of that type.
program Produce; type TListEntry = record Next: ^TListEntry; (*<-- Error message here*) Data: Integer; end; TMyClass = class; (*<-- Error message here*) TMyClassRef = class of TMyClass; TMyClasss = class (*<-- Typo ...*) (*...*) end; begin end.
The example tries to refer to record type before it is completely defined. Also, because of a typo, the compiler never sees a complete declaration for TMyClass.
program Solve; type PListEntry = ^TListEntry; TListEntry = record Next: PListEntry; Data: Integer; end; TMyClass = class; TMyClassRef = class of TMyClass; TMyClass = class (*...*) end; begin end.
The solution for the first problem is to introduce a type declaration for an auxiliary pointer type. The second problem is fixed by spelling TMyClass correctly.
