减小Delphi XE5编译出来的程序体积

默认Delphi XE5 编译出来的程序体积很大。

一般用两个方法可以很大程度上减少程序体积。

一、在工程中用编译指令禁用RTTI

禁用的方法很简单，就是要在工程的Uses语句前添加下面的定义就可以了：

{ Reduce EXE size by disabling as much of RTTI as possible (delphi 2009/2010) }

{$IF CompilerVersion >= 21.0}

{$WEAKLINKRTTI ON}

{$RTTI EXPLICIT METHODS([]) PROPERTIES([]) FIELDS([])}

{$IFEND}

示例：

program Project1;

{ Reduce EXE size by disabling as much of RTTI as possible (delphi 2009/2010) }

{$IF CompilerVersion >= 21.0}

{$WEAKLINKRTTI ON}

{$RTTI EXPLICIT METHODS([]) PROPERTIES([]) FIELDS([])}

{$IFEND}

uses

Vcl.Forms,

Unit1 in 'Unit1.pas' {Form1};

{$R *.res}

begin

Application.Initialize;

Application.MainFormOnTaskbar := True;

Application.CreateForm(TForm1, Form1);

Application.Run;

end.

二、关闭DEBUG信息

Project->options->Linking->debug information 设置为False即可

新建工程：默认编译文件大小为：9782KB

使用上述办法瘦身：程序大小为：1900KB
