在iOS上使用cv :: minMaxLoc（）时发生编译错误

Question

I am using OpenCV on iOS, the project works fine and can detect harris corners but when I try to use the following line I get a compile error:

cv::minMaxLoc(cornerStrength,&minStrength,&maxStrength);

The error from xcode is:

Undefined symbols for architecture armv7: "___udivmodsi4", referenced from: cv::minMaxIdx(cv::_InputArray const&, double*, double*, int*, int*, cv::_InputArray const&)in OpenCV(stat.o) ld: symbol(s) not found for architecture armv7 collect2: ld returned 1 exit status

Any advice much appreciated as I cant find a way past this at the moment.

Cheers, Fraser

如果您使用的是LLVM GCC 4.x，请尝试将编译器更改为Apple LLVM 3.x，这对我有用。
