C++ 关于Xcode中OpenCV的链接错误

我使用的是XCode4和OpenCV 2.3。 我已经编译了一份OpenCV。以下是.a的信息：

libopencv_core.a: Mach-O universal binary with 3 architectures
libopencv_core.a (for architecture armv7):  current ar archive random library
libopencv_core.a (for architecture armv6):  current ar archive random library
libopencv_core.a (for architecture i386):   current ar archive random library

我将其拖到Frameworks floder，并设置库搜索的正确路径。 但当我编译时，出现了这样的错误：

OpenCV库中使用的STL似乎没有链接到.a文件中。 如何修复它

谢谢，鲍

ld:未找到架构armv7的符号 collect2:ld返回了1个退出状态

顺便说一句：当我将文件名设置为.mm时，链接器会报告内部编译器错误。总线错误。

我得到了答案

OpenCV中的MIN宏与Xcode中预定义的MIN冲突

将.m文件重命名为.mm，并将all MIN函数更改为新名称，例如OpenCV头文件中的CV_MIN

检查

Bing，关于OpenCV的最小（和最大）宏，您是正确的。我必须重新命名它们，可能是因为v2.0:）

但是，没有必要将所有的.m文件重命名为.mm文件，因为Xcode在默认情况下会对它们进行不同的处理——即Objec
