Please use always the latest release compiler (2.4.2) as starting
compiler to build a new fpc.
NB - I am using FPC 2.4.2.
type
Terrain_type = (Land, Sea);
exit_type = array[ directions ] of integer;
description_type = array[1..2] of string;
Tmap_detail = Object
FTerrain : Terrain_type;
FTerrain_char : char;
Fdescription : description_type;
Fx, Fy, Flocation_number : integer;
Fexits : exit_type;
end;
// The Island class definition
Generic TIsland<T> = class
Items : array of Tmap_detail;
public
constructor Create(AList: TList);: [Lazarus] dtm_maker project compile
errors with TList code.
procedure Add( Value : Tmap_detail );
end;
var
Form1: TForm1;
Island : TIsland; // line 144
Unit1.pas >>> http://pastebin.com/wuEft4Kb
Why do you declare TIsland as a generic if you don't use the type "T"
anywhere?
Nevertheless, you need to declare a specialized type of a generic, so
you're able to use it.
Example:
type
TIntegerIsland = specialize TIsland<Integer>;
var
Island: TIntegerIsland;
(...)

Sven
