gcc libxml.c -o libxml -I /usr/local/libxml/include/libxml2/

报错：
libxml.c: 在函数‘parseDoc’中:

libxml环境建产过程：
我下载的llibxml2-2.7.4.tar.gz，configure --prefix=/usr/local/libxml ;make ; make install

然后ln -s /usr/loscl/libxml/include/libxml2 /usr/include/libxml2

源码是这样的:

#include <stdio.h>
#include <string.h>
#include <stdlib.h>
#include "libxml/parser.h"
#include "libxml/tree.h"
#include "libxml/xmlmemory.h"

#include <stdio.h>
//#include "libxml.h"

static void parseDoc(char *docname)
{
      xmlDocPtr doc;
      xmlNodePtr cur;
      doc = xmlParseFile(docname);
      xmlChar keyword;
      if (doc == NULL)
      {
            fprintf(stderr,"Document not parsed successful. \n"

;
            return;
      }

      cur = xmlDocGetRootElement(doc);

      if(cur == NULL)
      {
            fprintf(stderr,"This xml file is empty \n"

;
            xmlFreeDoc(doc);
            return;
      }

      if (xmlStrcmp(cur->name, (const xmlChar*) "root"

)
{
fprintf(stderr,"document of the wrong type,root node not exist.\n"

;
            xmlFreeDoc(doc);
            return;
      }

      cur=cur->xmlChildrenNode;
      while (cur != NULL)
      {
            keyword = xmlNodeListGetString(doc,cur->xmlChildrenNode,1);
            printf("%s \d" , keyword);
      }

}

main(int argc, char **argv) {
      char *docname;
      if (argc <= 1) {
      printf("Usage: %s docname\n", argv[0]);
      return(0);
      }
      docname = argv[1];
      parseDoc (docname);
      return (1);
      }
