xcode - 为什么我不能编译这个命令行 OpenCV Mac 应用程序？

Question

以下是我的步骤:

1)创建命令行工具工程“OpenCV”

2)在工程中添加/usr/local/lib目录下后缀为2.4.2的文件，如“libopencv_calib3d.2.4.2.dylib”

3)添加“/usr/local/include”到项目的Header Search Path

4) 输入这个程序:

#include <opencv2/opencv.hpp>
#include <opencv2/highgui/highgui.hpp>
#include <opencv/cvaux.hpp>

int main(int argc, char** argv)
{
    IplImage * pInpImg = 0;

    // Load an image from file - change this based on your image name
    pInpImg = cvLoadImage("my_image.jpg", CV_LOAD_IMAGE_UNCHANGED);
    if(!pInpImg)
    {
        fprintf(stderr, "failed to load input image\n");
        return -1;
    }

    // Write the image to a file with a different name,
    // using a different image format -- .png instead of .jpg
    if( !cvSaveImage("my_image_copy.png", pInpImg) )
    {
        fprintf(stderr, "failed to write image file\n");
    }

    // Remember to free image memory after using it!
    cvReleaseImage(&pInpImg);

    return 0;
}

但是，我得到错误:

ld: library not found for -lopencv_calib3d.2.4.2
clang: error: linker command failed with exit code 1 (use -v to see invocation)

问题出在哪里？

我正在使用 mountain lion 和 Xcode 4.4

您不需要将 opencv 库添加到您的项目中，但您需要链接到这些库并设置库搜索路径。我能够使用这些设置编译和运行您的程序:
