problem in myGMMbackground.h

When i run your codes in Visual Studio, it always reports errors.

typedef struct MyCvGaussBGValues  
{  
    float match_sum;  
    float weight;  
    float mean[3];  
    float variance[3];  
}  
MyCvGaussBGValues; 

MyCvGaussBGValues *g_point = (MyCvGaussBGValues *) ((CvMat*)(bg_model->g_point))->data.ptr;  
MyCvGaussBGValues *mptr = g_point;  

Do these codes have some problems?
