【问题描述】:
以下是我的步骤:
1)创建命令行工具项目“OpenCV”
2) 将文件添加到 /usr/local/lib 下的项目中,后缀为 2.4.2,例如 "libopencv_calib3d.2.4.2.dylib"
3)将“/usr/local/include”添加到项目的头文件搜索路径
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?
我正在使用山狮和 Xcode 4.4
