Question

我正在使用MPI和Opencv库文件将c程序写入我的raspberry pi。当我的c程序尝试使用像cvCreateImage和cvGet2D这样的opencv函数时，它总是会出现这个错误：

=   BAD TERMINATION OF ONE OF YOUR APPLICATION PROCESSES
=   EXIT CODE: 11
=   CLEANING UP REMAINING PROCESSES
=   YOU CAN IGNORE THE BELOW CLEANUP MESSAGES

这是我的c程序：

    #include <mpi.h>
    #include </home/pi/opencv-2.4.8/include/opencv/cv.h>
    #include </home/pi/opencv-2.4.8/include/opencv/highgui.h>

    #include <math.h>

    #define IMAGE_SIZE      1024
    #define NUM_CELLS       4

    typedef struct {int r,i;} mycomplex;
    int     numtasks;               /* Number of processors */
    int     taskid;                 /* ID number for each processor */
    int     checkpoint;
    int     dt[10], sum;



    int main(int argc,char *argv[])
    {
        int rc, cell, i, j, k, n, nx, logn, errors, sign, flops;
        float mflops;
        checkpoint=0;

    /*****************************************************************************/
        /* Initialize MPI environment and get task's ID and number of tasks 
            * in the partition. */
          rc = MPI_Init(&argc,&argv);
          rc|= MPI_Comm_size(MPI_COMM_WORLD,&numtasks);
          rc|= MPI_Comm_rank(MPI_COMM_WORLD,&taskid);

        if(taskid==0)
        {
            //getimage();   
            IplImage *image;
            IplImage *grayimage;
            image=cvLoadImage("one.jpg",-1);
            grayimage=cvCreateImage(cvSize(image->width,image->height),IPL_DEPTH_8U,1);
            cvCvtColor(image,grayimage,CV_RGB2GRAY);

            for(i=0;i<image->height;i++)
            {

                for(j=0;j<image->width;j++)
                {
                    CvScalar scal=cvGet2D(image,i,j);
                    printf("(%d) ",(int)scal.val[0]);
                }
                printf("\n");       
            }
        cvWaitKey(0);
        cvReleaseImage(&image); 
        }
        MPI_Barrier(MPI_COMM_WORLD);

        /* Must have 4 tasks for this program */
        if (numtasks != NUM_CELLS)
        {
           printf("Error: this program requires %d MPI tasks\n", NUM_CELLS);
            exit(1);
        }

        if (rc != MPI_SUCCESS)
           printf ("error initializing MPI and obtaining task ID information\n");
        else
             printf ("MPI task ID = %d\n", taskid);

       n = IMAGE_SIZE; //512
       /* compute logn and ensure that n is a power of two */
       nx = n;
       logn = 0;
       while(( nx >>= 1) > 0)
          logn++;           //logn=9 when nx=1 
       nx = 1;
       for (i=0; i<logn; i++)   //loop 9 times
          nx = nx*2;        //nx=nx*(2^9)=512
       if (nx != n)         //nx=512 = n=512 proved
       {
          (void)fprintf(stderr, "%d: fft size must be a power of 2\n", IMAGE_SIZE);
          exit(0);
       }
       .....

我使用的make文件似乎很好：

mpi_2dfft: mpi_2dfft.o   /home/pi/mpich2/lib/libmpich.a
    /home/pi/mpich2/bin/mpicc -o mpi_2dfft mpi_2dfft.o -I/usr/local/include/opencv -I/usr/local/include -L/usr/local/lib -lopencv_core -lopencv_imgproc -lopencv_highgui -lopencv_ml -lopencv_video -lopencv_features2d -lopencv_calib3d -lopencv_objdetect -lopencv_contrib -lopencv_contrib -lopencv_legacy -lopencv_flann -lwiringPi -lwiringPiDev -lpthread -lm

我可以知道为什么opencv函数不能在mpi中使用？ mpi与其他库有冲突吗？

Mpi不支持Opencv？
