"Missing full declaration for private type.." in Ada

Question

Hello.. I'm having a problem using a package ADS file in Ada. I'm getting an error of "Missing full declaration for private type LETTER". How do I deal with it?

this is the code I wrote:

package LETTER_SPEC is

type LETTER is private;

procedure DATE_OF_LETTER (THE_LETTER: in out LETTER; DATE: STRING);

procedure RECIPIENT_NAME (THE_LETTER: in out LETTER; NAME: STRING);

procedure SUBJECT_LINE (THE_LETTER: in out LETTER; SUBJECT: STRING);

procedure TEXT_OF_LETTER (THE_LETTER: in out LETTER; TEXT: STRING);

procedure SENDER_NAME (THE_LETTER: in out LETTER; NAME: STRING);

procedure PUT_LETTER (THE_LETTER: in LETTER);

private

type PTR_LETTER is access STRING;

type LETTER_DATA is

   record

      DATE_OF_LETTER: PTR_LETTER;

       RECIPIENT_NAME: PTR_LETTER;

      SUBJECT_LINE: PTR_LETTER;

       TEXT_OF_LETTER: PTR_LETTER;

       SENDER_NAME: PTR_LETTER;

   end record;

end LETTER_SPEC;'

Thanks in advance..

Answer 1

Ada complains because you declare in the private part a LETTER_DATA type and not a LETTER type.
