我从Macports安装了opencv，它就在 的/ opt /本地/包括
我试图通过提供以下命令从Terminal编译基本的OPENCV代码，但它没有被编译：
g++ example.cpp -o example -I /usr/local/include/opencv/ -L /usr/local/lib/ -lopencv_highgui -lopencv_calib3d -lopencv_legacy
g++ example.cpp -o example -I /opt/local/include/opencv/ -L /opt/local/lib/ -lopencv_highgui -lopencv_calib3d -lopencv_legacy
任何人都可以告诉我在Mac OS X 10,7下面的opencv程序下编译正确的终端命令吗？
我正在尝试编译此链接上给出的简单示例： http://www.cs.iit.edu/~agam/cs512/lect-notes/opencv-intro/
修改：
以下是我要编译的代码：
////////////////////////////////////////////////////////////////////////
//
// hello-world.cpp
//
// This is a simple, introductory OpenCV program. The program reads an
// image from a file, inverts it, and displays the result.
//
////////////////////////////////////////////////////////////////////////
#include <stdlib.h>
#include <stdio.h>
#include <math.h>
#include <cv.h>
#include <highgui.h>
int main(int argc, char *argv[])
{
IplImage* img = 0;
int height,width,step,channels;
uchar *data;
int i,j,k;
if(argc<2){
printf("Usage: main <image-file-name>\n\7");
exit(0);
}
// load an image
img=cvLoadImage(argv[1]);
if(!img){
printf("Could not load image file: %s\n",argv[1]);
exit(0);
}
// get the image data
height = img->height;
width = img->width;
step = img->widthStep;
channels = img->nChannels;
data = (uchar *)img->imageData;
printf("Processing a %dx%d image with %d channels\n",height,width,channels);
// create a window
cvNamedWindow("mainWin", CV_WINDOW_AUTOSIZE);
cvMoveWindow("mainWin", 100, 100);
// invert the image
for(i=0;i<height;i++) for(j=0;j<width;j++) for(k=0;k<channels;k++)
data[i*step+j*channels+k]=255-data[i*step+j*channels+k];
// show the image
cvShowImage("mainWin", img );
// wait for a key
cvWaitKey(0);
// release the image
cvReleaseImage(&img );
return 0;
}
以下是输出：

Package opencv was not found in the pkg-config search path.
Perhaps you should add the directory containing `opencv.pc'
to the PKG_CONFIG_PATH environment variable

答案 0 :(得分：18)
或使用 pkg-config 来帮助您填写路径和库：
g++ example.cpp -o example `pkg-config --cflags --libs opencv`
答案 1 :(得分：7)
耶!!!这个命令有效：
g++ hello-world.cpp -o hello-world `pkg-config --cflags --libs opencv`
我只需将opencv.pc文件的路径添加到.profile (or .bash_profile)即：
export PKG_CONFIG_PATH=/opt/local/lib/pkgconfig
现在我正在尝试编译使用
的文件#include <opencv2/opencv.hpp>
而不是
#include <cv.h>
#include <highgui.h>
如果相同的命令适用于此，我会很快回复。 非常感谢所有评论。
答案 2 :(得分：1)
你很亲密。 cvReleaseImage位于opencv_core中。我是通过在http://opencv.itseez.com搜索cvReleaseImage来了解到这一点的。这对我有用：
g++ hello-world.cpp -o hello-world -I /usr/local/include/opencv -L /usr/local/lib -lopencv_highgui -lopencv_core
如果您将/usr更改为/opt，那么它应该适合您。
修改
尝试在源代码中进行此更改：
#include "opencv.hpp"
//#include <cv.h>
//#include <highgui.h>
我认为问题源于您安装的教程代码和OpenCV 2.3之间的版本不匹配。他们更改了目录组织和库名称。
