OpenCV_1.1pre1a 安装以后有一些使用问题，库文件需要重新编译，打开_make文件夹，选择解决方案文件编译。编译过程中会遇到如下错误

//
...
cvbgfg_acmmm2003.cpp
D:/opencv5/cvaux/src/cvbgfg_acmmm2003.cpp(411) : error C2039: 'foreground_regions' : is not a member of 'CvFGDStatModel'
         ../include/cvaux.h(1240) : see declaration of 'CvFGDStatModel'
D:/opencv5/cvaux/src/cvbgfg_acmmm2003.cpp(416) : error C2039: 'foreground_regions' : is not a member of 'CvFGDStatModel'

将代码

//
    #define CV_BG_STAT_MODEL_FIELDS()                                                                   /
    int             type; /*type of BG model*/                                                                              /
    CvReleaseBGStatModel release;                                                                                  /
    CvUpdateBGStatModel update;                                                                                    /
    IplImage*       background;   /*8UC3 reference background image*/                    /
    IplImage*       foreground;   /*8UC1 foreground image*/                                          /
    IplImage**      layers;       /*8UC3 reference background image, can be null */   /
    int             layer_count; /* can be zero */                                                                      /
    CvMemStorage*   storage;      /*storage for 揻oreground_regions? /                  /
    CvSeq*          foreground_regions /*foreground object contours*/
//

更改为

//
    #define CV_BG_STAT_MODEL_FIELDS()                                                                   /
    int             type; /*type of BG model*/                                                                              /
    CvReleaseBGStatModel release;                                                                                  /
    CvUpdateBGStatModel update;                                                                                    /
    IplImage*       background;   /*8UC3 reference background image*/                    /
    IplImage*       foreground;   /*8UC1 foreground image*/                                          /
    IplImage**      layers;       /*8UC3 reference background image, can be null */   /
    int             layer_count; /* can be zero */                                                                      /
    CvMemStorage*   storage;      /*storage for 揻oreground_regions?* /                  /
    CvSeq*          foreground_regions /*foreground object contours*/
//

即可以解决。
