CEGUI を試しています。Archlinux のコミュニティ リポジトリから cegui パッケージをインストールしましたが、基本的な hello world をコンパイルできません。

コードは次のとおりです。

#include <CEGUI/CEGUI.h>¬                                                       
¬                                                                               
using namespace std;¬                                                           
using namespace CEGUI;¬                                                         
¬                                                                               
int main(int argc, char *argv[]) {¬                                             
    WindowManager& wmgr = WindowManager::getSingleton();¬                       
    Window* myRoot = wmgr.createWindow( "DefaultWindow", "root" );¬             
    System::getSingleton().getDefaultGUIContext().setRootWindow( myRoot );¬     
    FrameWindow* fWnd = static_cast<FrameWindow*>(¬                             
    ¦   ¦   ¦   wmgr.createWindow( "TaharezLook/FrameWindow", "testWindow" ));¬ 
    myRoot->addChild( fWnd );¬                                                  
    // position a quarter of the way in from the top-left of parent.¬           
    fWnd->setPosition( UVector2( UDim( 0.25f, 0.0f ), UDim( 0.25f, 0.0f ) ) );¬ 
    // set size to be half the size of the parent¬                              
    fWnd->setSize( USize( UDim( 0.5f, 0.0f ), UDim( 0.5f, 0.0f ) ) );¬          
    fWnd->setText( "Hello World!" );¬                                           
}¬

でコンパイルするとg++ -o hello hello.cpp、次のメッセージが表示されます。
