我正在尝试使用 Xcode 4.5 在 Mountain Lion 10.8 上编译一个使用 OpenCV 的项目，我严格遵循了此链接上的步骤:
在 OS X Lion / Mountain Lion 上使用 Xcode 编译 OpenCV (2.3.1+)
这是我遵循的步骤：
- 使用 ports 安装 opencv：sudo port install opencv configure.compiler = llvm-gcc-4.2
- 打开 Xcode 并创建一个新项目（使用 c++ 命令行应用程序）。
- 将“/opt/local/lib/**”路径添加到“库搜索路径”中
- 将任何 libopencv_. Dylib 添加到一个新组中
- 将“/opt/local/include/**”路径添加到“头文件搜索路径”中
每次我尝试编译时，Xcode 都会失败并出现以下错误：

我也尝试更改编译器为LLVM GCC 4.2编译器，但没有成功。有人能告诉我在xcode中使用opencv Mountain Lion和Xcode 4.5构建项目的确切步骤吗？
