编译第一个LINUX下 OPENCV 程序

程序如下:

test1.c

  1 #include <highgui.h>
  2 #include <cv.h>
  3 
  4 int main(int argc, char **argv)
  5 {
  6   cvNamedWindow("Test1", CV_WINDOW_AUTOSIZE);
  7   CvCapture * capture = cvCreateFileCapture(argv[1]);
  8 
  9   IplImage *frame;
 10 
 11   while (1) {
 12     frame = cvQueryFrame(capture);
 13 
 14     if (!frame) break;
 15 
 16     cvShowImage("Test1", frame);
 17 
 18     char c = cvWaitKey(33);
 19 
 20     if (27 == c) break;
 21   }
 22 
 23   cvReleaseCapture(&capture);
 24   cvDestroyWindow("Test1");
 25 }

设置:

 67 PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig
 68 export PKG_CONFIG_PATH
 69 export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib

编译:

g++  test1.c -o test1 `pkg-config --libs --cflags opencv` 

OK.
