Right to use this code in any way you want without warrenty, support or any guarentee of it working.

------解决方案--------------------
改成这样就可以了，我已调试通过：
#include <stdio.h>
#include <cv.h>
#include <highgui.h>
#include <stdio.h>
void f(
IplImage* src,
IplImage* dst
) {
CvMemStorage* storage = cvCreateMemStorage(0);
CvSeq* comp = NULL;
cvPyrSegmentation( src, dst, storage, &comp, 4, 200, 50 );
int n_comp = comp->total;
for( int i=0; i<n_comp; i++ ) {
CvConnectedComp* cc = (CvConnectedComp*) cvGetSeqElem( comp, i );
// do_something_with( cc );
}
cvReleaseMemStorage( &storage );
}
int main(int argc, char** argv)
{
// Create a named window with a the name of the file.
cvNamedWindow( "201001071230101.jpg", 1 );
// Load the image from the given file name.
IplImage* src = cvLoadImage( "201001071230101.jpg" );
if(!src) { printf("Couldn't seem to Open %s, sorry\n",argv[1]); return -1;}
IplImage* dst = cvCreateImage( cvGetSize(src), src->depth, src->nChannels);
