一个简单的程序

1. #include<stdio.h>
   
2. #include<stdio.h>
   
3. 
   
4. #include "mysql.h"
   
5. 
   
6. int main(int argc,char *argv[]){
   
7.   MYSQL *conn_ptr;
   
8.   conn_ptr=mysql_init(NULL);
   
9.   conn_ptr=mysql_real_connect(conn_ptr,"localhost","root","password","mysql",0,NULL,0);
   
10.   if(conn_ptr){
    
11.     printf("connection success\n");
    
12.   }else{
    
13.     printf("connection fail\n");
    
14.   }
    
15.    mysql_close(conn_ptr);
    
16.    return 1;
    
17. }

用gcc -I/usr/include/mysql connect.c -L/usr/lib/mysql -lmysqlclient -o connect 编译
老是出现错误:
/usr/lib/mysql/libmysqlclient.a(my_compress.o)(.text+0xdd): In function `my_compress_alloc':
: undefined reference to `compress'
/usr/lib/mysql/libmysqlclient.a(my_compress.o)(.text+0x180): In function `my_uncompress':
: undefined reference to `uncompress'
collect2: ld returned 1 exit status
这是怎么回事?
搞了一下午了,都没搞定,郁闷
哪个大侠告诉我错在哪里?

compress好象是libz.so中的函数。你再连接上-lz看看。
