遇到如下困惑，请赐教：
一、问题描述
调《Pro OGRE 3D Programming》一书的程序时，出现如下报错信息：
错误行：
// set up the render window with all default params
RenderWindow *window = rSys->createRenderWindow(
"Manual Ogre Window", // window title
800, // window width, in pixels
600, // window height, in pixels
false, // fullscreen or not
0); // use defaults for all other values
错误提示：
error C2039: “createRenderWindow”: 不是“Ogre::RenderSystem”的成员
错误行：
Timer *timer = PlatformManager::getSingleton().createTimer();
错误提示：
error C2653: “PlatformManager”: 不是类或命名空间名称
error C2228: “.createTimer”的左边必须有类/结构/联合
出现如下错误后，我在网上找了一些相关资料，其中我想按如下方式试图解决此问题，可问题仍未能解决：
http://203.208.35.101/search?q=cache:eF59R75sVZQJ:bbs.ogre3d.cn/viewthread.php%3Ftid%3D175+%E2%80%9CPlatformManager%E2%80%9D:+%E4%B8%8D%E6%98%AF%E7%B1%BB%E6%88%96%E5%91%BD%E5%90%8D%E7%A9%BA%E9%97%B4%E5%90%8D%E7%A7%B0&cd=4&hl=zh-CN&ct=clnk&gl=cn&st_usg=ALhdy2-WSVI_jtCXXE0uGw01gmIHwGtEEA
我在“工具》选项》C++目录”下的include和lib选项下分别添加了：
包含文件（OgreSdk的安装目录为）：
C:\OgreSDK\include库文件：
C:\OgreSDK\lib
二、我的编码过程：
1、用appwizard创建一个Ogre空项目。
2、新建一个.cpp文件，将如下内容复制到该文件中：
#include "Ogre.h"
#include <iostream>
#if defined(WIN32)
#include <windows.h>
#endif
using namespace Ogre;
#if defined(WIN32)
INT WINAPI WinMain (
HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPSTR lpCmdLine,
int nCmdShow
)
#else
int main(int argc, char *argv[])
#endif
{
// tell Root not to load from any plugins or settings file
Root *root = new Root("", "");
// Load feature plugins. Scene managers will register
// themselves for all scene types they support
root->loadPlugin(" lugin_CgProgramManager");
root->loadPlugin("Plugin_OctreeSceneManager");
// load rendersystem plugin(s). The order is important in that GL
// should be available on on platforms, while D3D9 would be available
// only on Windows -- the try/catch will intercept the exception in this
// case where D3D9 is not available and continue gracefully.
try {
root->loadPlugin("RenderSystem_GL");
root->loadPlugin("RenderSystem_Direct3D9");
}
catch (...) {}
try {
// We'll simulate the selection of a rendersystem on an arbirtary basis; normally
// you would have your own code to present the user with options and select the
// rendersystem on that basis. Since a GUI is beyond the scope of this example, we'll
// just assume the user selected OpenGL.
RenderSystemList *rList = root->getAvailableRenderers();
RenderSystemList::iterator it = rList->begin();
RenderSystem *rSys = 0;
while (it != rList->end()) {
rSys = *(it++);
if (rSys->getName().find("OpenGL")) {
root->setRenderSystem(rSys);
break;
}
}
// check to see if a render system was selected; if we reached the end of the list
// without selecting a render system then none was found.
if (rSys == 0) {
delete root;
std::cerr << "No RenderSystem available, exiting..." << std::endl;
return -1;
}
// We can initialize Root here if we want. "false" tells Root NOT to create
// a render window for us
root->initialise(false);
// set up the render window with all default params
RenderWindow *window = rSys->createRenderWindow(
"Manual Ogre Window", // window title
800, // window width, in pixels
600, // window height, in pixels
false, // fullscreen or not
0); // use defaults for all other values
// from here you can set up your camera and viewports as normal
// get a pointer to the default base scene manager -- sufficient for our purposes
SceneManager *sceneMgr = root->createSceneManager(ST_GENERIC);
// create a single camera, and a viewport that takes up the whole window (default behavior)
Camera *camera = sceneMgr->createCamera("MainCam");
Viewport *vp = window->addViewport(camera);
vp->setDimensions(0.0f, 0.0f, 1.0f, 1.0f);
camera->setAspectRatio((float)vp->getActualWidth() / (float) vp->getActualHeight());
camera->setFarClipDistance(1000.0f);
camera->setNearClipDistance(5.0f);
// Run the manual render loop. Since we are not using a frame listener in this case, we
// will count to 15 seconds and then instead of exiting, we'll change the render window settings
// and re-initialize it.
bool renderLoop = true;
Timer *timer = PlatformManager::getSingleton().createTimer();
timer->reset();
float s = 0.0f;
while (renderLoop && window->isActive()) {
renderLoop = root->renderOneFrame();
// accumulate total elapsed time
s += (float)timer->getMilliseconds() / 1000.0f;
// if greater than 15 seconds, break out of the loop
if (s >= 15.0f)
renderLoop = false;
// we must call the windowing system's message pump each frame to
// allow Ogre to process messages
//PlatformManager::getSingleton().messagePump();
}
}
catch (Exception &e) {
std::cerr << e.getFullDescription() << std::endl;
}
delete root;
return 0;
}
