Compiling GMLib 1.1.0 in XE5

Question

I managed to solve several issues and install the "GMLib_DXE4.bpl".

Now I have two problems with compiling "GMLib_DXE4_VCL.bpl".

[dcc32 Error] GMMapVCL.pas(124): E2003 Undeclared identifier: 'TTimer'

[dcc32 Error] WebControlVCL.pas(180): E2029 Identifier expected but 'IMPLEMENTATION' found : Solved.

Regarding TTimer:

    uses
  {$IFDEF WEBBROWSER}
  SHDocVw,
    {$IFDEF DELPHIXE2}
    Vcl.ExtCtrls,
    {$ELSE}
    ExtCtrls,
    {$ENDIF}
  {$ENDIF}

  {$IFDEF CHROMIUM}
  cefvcl, ceflib, cefgui,
  {$ENDIF}

  {$IFDEF DELPHIXE2}
  System.SysUtils, System.Classes, Vcl.Dialogs, Vcl.Graphics,
  {$ELSE}
  SysUtils, Classes, Dialogs, Graphics,
  {$ENDIF}

  GMMap, GMFunctionsVCL;

Regarding implementation: Solved.

    unit WebControlVCL;

    {.$DEFINE WEBBROWSER}
    {.$DEFINE CHROMIUM}
    {$I ..\gmlib.inc}

    interface

      WebControl;

    type

      TWebControl = class(TCustomWeb)
      protected

        function WebFormFieldValue(const FormIdx: Integer; const FieldName: string): string; overload; override;
      public
         constructor Create(WebBrowser: TWebBrowser); reintroduce; virtual;

      end;
      {$ENDIF}

      {$IFDEF CHROMIUM}
      TWebChromium = class(TCustomWebChromium)

You are using an out of date version of GMLib. As a general rule, never download the pre-packaged version of an open source project. Developers have a habit of not updating these pre-packaged downloads as frequently as you might like.

Instead, always go to the revision control repository to get the latest version. In this case it is here: https://code.google.com/p/gmlibrary/source and does appear to have been updated to support XE5.

FWIW your problem could almost certainly have been solved by way of a simple modification to the include file gmlib.inc. That file needs to be made aware of the new version. Take a look at the diffs for the latest revision for that file: https://code.google.com/p/gmlibrary/source/diff?spec=svn142&r=127&format=side&path=/trunk/gmlib.inc&old_path=/trunk/gmlib.inc&old=116

As you can see, all that is needed is to follow the pattern established for the other versions and add defines for XE5.
