关于Xcode中OpenCV的链接错误

Question

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

我将它拖到Frameworks floder中,并设置库搜索的正确路径.但是当我编译时,它发生了这样的错误:

似乎在OpenCV lib中使用的STL没有链接在.a文件中.怎么解决？

谢谢,低头.

ld:找不到架构armv7的符号:collect2:ld返回1退出状态

BTW:当我将文件名设置为.mm时,链接器报告内部编译器错误.总线错误.

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