谁能帮我解决一下问题？谢谢了

下面是我用 UF_CURVE_create_line这个函数的一段代码：
        UF_CURVE_line_t line1 ;
        UF_CURVE_line_t line2 ;
        UF_CURVE_line_t line3 ;
   
  line1.start_point[0] = node[n1].x ;
  line1.start_point[1] = node[n1].y ;
  line1.start_point[2] = node[n1].z ;
  line1.end_point[0] = node[n2].x ;
  line1.end_point[1] = node[n2].y ;
  line1.end_point[2] = node[n2].z ;
   
  line2.start_point[0] = node[n2].x ;
  line2.start_point[1] = node[n2].y ;
  line2.start_point[2] = node[n2].z ;
  line2.end_point[0] = node[n3].x ;
  line2.end_point[1] = node[n3].y ;
  line2.end_point[2] = node[n3].z ;
  line3.start_point[0] = node[n3].x ;
  line3.start_point[1] = node[n3].y ;
  line3.start_point[2] = node[n3].z ;
  line3.end_point[0] = node[n1].x ;
  line3.end_point[1] = node[n1].y ;
  line3.end_point[2] = node[n1].z ;
        tag_t line[3] ;
UF_CURVE_create_line(&line1 , &line[0]) ;
UF_CURVE_create_line(&line2 , &line[1]) ;
UF_CURVE_create_line(&line3 , &line[2]) ;


运行之后出现下面的错误：

别人都跟我用的一样，为什么我的出这么多错误呢？
望大侠们指点我一下，谢谢了
