!!Minimal Application Using Custom Main Loop
If you have any comments let me know. This code example is briefly discussed here [http://www.ogre3d.org/phpBB2/viewtopic.php?t=27924].

{CODE(wrap="1", colors="c++")} #include <Ogre.h> 
 
 using namespace Ogre; 
 
 void initResources(){ 
         ResourceGroupManager &resources=ResourceGroupManager::getSingleton(); 
         resources.addResourceLocation("data","FileSystem"); 
         resources.initialiseAllResourceGroups(); 
 } 
 Root* initOgre(){ 
        Root* root = new Root;
        #if defined(_DEBUG)
		root->loadPlugin("C:/OGRESDK/bin/debug/RenderSystem_GL_d.dll");
                //Linux
                //root->loadPlugin("/usr/local/lib/OGRE/RenderSystem_GL_d");  
        #else
                root->loadPlugin("C:/OGRESDK/bin/release/RenderSystem_GL.dll");
                //Linux
                //root->loadPlugin("/usr/local/lib/OGRE/RenderSystem_GL");  
        #endif


                const Ogre::RenderSystemList& rs = root->getAvailableRenderers();
        if(&rs && rs.size()&&rs.at(0)->getName().compare("RenderSystem_GL")){ 
                 RenderSystem * r=rs.at(0);

         }else{ 
                 exit(1); 
         } 
 
         initResources();
