使用OGRE库为Simulator编译iPhone应用程序时出现链接器错误

我正在尝试使用OGRE框架构建一个iPhone应用程序，并且在构建模拟器时遇到链接器错误，我不确定如何修复。

我使用OGRE iPhone模板创建了Xcode项目。我正在使用来自主网站Ogre_iOS_4.0_Dependencies_20100623的OGRE的静态库，并尝试为iOS 4.1模拟器构建。我在Mac OS X 10.6.4上使用Xcode 3.2.4构建。

编译似乎工作正常，但当它进入链接阶段时，我收到以下错误：

我该如何解决这个问题？感谢。

对于正确的iOS SDK版本，您可能需要正确的预编译Ogre依赖项（Masterfalcon会定期在ogre3d.org上发布这些依赖项）。 类似的链接器错误通常是由不正确的iPhoneDependencies（为您拥有的旧版iPhoneSKD构建）引起的。

只需按照此处列出的说明操作即可： http://www.ogre3d.org/tikiwiki/Building+Ogre+with+CMake Secion“为iPhone配置”。 一切都应该建立好。
