c - opencv 无法与 NetBeans 一起使用

Question

我正在尝试在 netbeans 上使用 opencv 用 c++ 编写这个简单的图像修改器程序。我使用的是ubuntu 10.04。每次我尝试运行或编译它时，它都会返回以下错误。我在链接器和附加工具中配置了 opencv。出了什么问题？

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;  
}

好吧，先生，这是您的编译行:

g++    -c -g -MMD -MP -MF build/Debug/GNU-Linux-x86/main.o.d -o build/Debug/GNU-Linux-x86/  main.o main.cpp

当您使用 <> 包含 header 时:

#include <cv.h>  
#include <highgui.h>  

编译器将在默认包含路径中搜索这些文件，通常是:/usr/include

因此，知道 opencv 不会将其开发文件安装在此目录中，我必须建议您找到它们。 如果 opencv 已正确安装在系统上，命令 pkg-config --cflags opencv 将告诉您它们在哪里。来吧，尝试一下。您还可以执行 pkg-config --libs opencv 来查找必须添加到编译中的库。

总而言之，如果您打开终端并 cd 到源代码所在的目录，下面的命令可能会编译您的项目IF您正确安装了 opencv已安装。

g++ -c -g -MMD -MP -MF build/Debug/GNU-Linux-x86/main.o.d -o build/Debug/GNU-Linux-x86/  main.o main.cpp `pkg-config --cflags opencv` `pkg-config --libs opencv`

你知道吗？我只是粘贴一些代码(opencv/camera)here (我们称之为funcam.cpp)。您可以使用它来测试 OpenCV 是否已安装并在您的系统上编译内容。您可以使用以下命令进行编译:

g++ funcam.cpp -o funcam `pkg-config --cflags opencv` `pkg-config --libs opencv`

如果它有效，您必须弄清楚如何配置 Netbeans。如果没有，您需要正确安装 OpenCV。
