XCode编译iphone opencv2出错

今天发现使用新的opencv2版本的方法显示一张图片时，代码如下：

#include
#include
#include
using namespace cv;
using namespace std;
int main(int argc, const char * argv[])
{
    Mat image;
    image = imread("./baby.jpg");
    if (!image.data) {
        cout << "Could not read the image" <<endl;
        return -1;
    }
    char windowName[] = "Study01";
    namedWindow(windowName, CV_WINDOW_AUTOSIZE);
    imshow(windowName, image);
    waitKey(0);
    return 0;
}

编译器显示如下错误：

Undefined symbols for architecture x86_64: “cv::namedWindow(std::__1::basic_string, std::__1::allocator > const&, int)”, referenced from: _main in main.o “cv::imread(std::__1::basic_string, std::__1::allocator > const&, int)”, referenced from:_main in main.o “cv::imshow(std::__1::basic_string, std::__1::allocator > const&, cv::_InputArray const&)”, referenced from: _main in main.o ld: symbol(s) not found for architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation)

google后初步分析为C++库和opencv库编译不一致，将XCode的C++ Standard Library改为GNU C++ standard library即可正常编译显示图片。此处仍有疑问，待日后考虑清楚。
