我正在使用 XCode4 和 OpenCV 2.3。 我编译了一份 OpenCV。这是 .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

我把它拖到Frameworks floder，并设置正确的库搜索路径。 但是我编译的时候出现了这样的错误:

似乎 OpenCV 库中使用的 STL 未链接到 .a 文件中。 如何解决？

谢谢，鞠躬。

架构 armv7 的 undefined symbol :

ld: 未找到体系结构 armv7 的符号 collect2: ld 返回 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。

最佳答案

您可以通过“Build Phases -> Link Binary With Libraries”设置与 c++ 标准库的链接

关于c++ - Xcode 中关于 OpenCV 的链接错误，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/7701393/
