我想用如下的程序生成一个图形，编译，连接都通过了，可是图形就是出不来，为什么？请版主及各位高人不吝赐教！帮帮忙！
  
程序如下：
#include <stdio.h>
#include <uf.h>
#include <uf_modl.h>
#include <uf_disp.h>
#include <uf_part.h>
  
#define UF_CALL(X) (report( __FILE__, __LINE__, #X, (X)))
  
static int report( char *file, int line, char *call, int irc)
{
   if (irc)
   {
      char    messg[133];
      printf("%s, line %d:  %s\n", file, line, call);
      (UF_get_fail_message(irc, messg)) ?
        printf("    returned a %d\n", irc) :
        printf("    returned error %d:  %s\n", irc, messg);
   }
   return(irc);
}
  
static void do_ugopen_api(void)
{
  
   double origin[3] = {0.0, 0.0, 0.0};
   double orig_hole[3] = {0.0, 0.0, 12};
   double orig_hole3[3] = {0.0, -80, 9.5};
   double orig_hole2[3] = {0.0, -80, 0.0};
   double direction[3] = {0.0, 0.0, 1.0};
   char *h = "20";
   char *D = "108";
   char *h1 = "12";
   char *d1 = "48";
   char *h2 = "10.5";
   char *d22 = "8";
   char *d3 = "16";
   char *d2 = "10.5";
   char *h22 = "9.5";
     
   char *d = "42";
   char *part_name="cover";  
   
UF_FEATURE_SIGN create = UF_NULLSIGN;
   UF_FEATURE_SIGN sub = UF_NEGATIVE;
   tag_t cover_id, hole_id, hole1_id, hole2_id, hole3_id,feat_obj,part;
   uf_list_p_t feat_list;
  int units = 1;
   
UF_CALL(UF_PART_new(part_name, units, &part))
