FastDFS_V5.05版本升级说明

gg9654

为了大家避免，在升级FastDFS是碰到问题，分享一下，我升级版本的经验。

一、问题概述

最近从5.02 升级到V5.05 出现了一些编译上的问题，比如函数未定义之类的。系统采用的Centos 6.4 X64, 具体编译错误 如下

1. trunk_mgr/trunk_mem.o: In function `storage_trunk_free_node':
   
2. /usr/local/src/FastDFS/storage/trunk_mgr/trunk_mem.c:639: undefined reference to `fast_mblock_free'
   
3. trunk_mgr/trunk_mem.o: In function `trunk_add_free_block':
   
4. /usr/local/src/FastDFS/storage/trunk_mgr/trunk_mem.c:1192: undefined reference to `fast_mblock_alloc'
   
5. trunk_mgr/trunk_mem.o: In function `trunk_add_space_by_node':
   
6. /usr/local/src/FastDFS/storage/trunk_mgr/trunk_mem.c:600: undefined reference to `fast_mblock_free'

10. /usr/local/src/FastDFS/storage/trunk_mgr/trunk_mem.c:1494: undefined reference to `fast_mblock_free'
    
11. trunk_mgr/trunk_mem.o: In function `trunk_delete_size_tree_entry':
    
12. /usr/local/src/FastDFS/storage/trunk_mgr/trunk_mem.c:1261: undefined reference to `fast_mblock_free'
    
13. trunk_mgr/trunk_mem.o: In function `trunk_delete_space':
    
14. /usr/local/src/FastDFS/storage/trunk_mgr/trunk_mem.c:1345: undefined reference to `fast_mblock_free'
    
15. trunk_mgr/trunk_mem.o: In function `trunk_split':
    
16. /usr/local/src/FastDFS/storage/trunk_mgr/trunk_mem.c:1406: undefined reference to `fast_mblock_alloc'
    
17. /usr/local/src/FastDFS/storage/trunk_mgr/trunk_mem.c:1422: undefined reference to `fast_mblock_free'
    
18. trunk_mgr/trunk_mem.o: In function `trunk_free_space':
    
19. /usr/local/src/FastDFS/storage/trunk_mgr/trunk_mem.c:1150: undefined reference to `fast_mblock_alloc'

22. /usr/local/src/FastDFS/storage/trunk_mgr/trunk_mem.c:305: undefined reference to `fast_mblock_destroy'
    
23. trunk_mgr/trunk_mem.o: In function `storage_trunk_restore':
    
24. /usr/local/src/FastDFS/storage/trunk_mgr/trunk_mem.c:760: undefined reference to `fast_mblock_alloc'
    
25. trunk_mgr/trunk_mem.o: In function `storage_trunk_init':

二、问题原因

这是由于老的libfastcommon无法支持新版的FastDFS。如果只是单纯编译新的libfastcommon，老的lib库不删除的话，会导致编译时链接到老的库，就是出现许多函数未定义，网上很多说要卸载FastDFS系统在安装，其实不用，只要将老的libfastcommon库删除就可以了。

三、解决方案

下面给出 具体指令，自测通过 仅供参考

1. rm -rf /usr/local/lib/libfdfs*
   
2. rm -rf /usr/local/lib/libfast*
   
3. rm -rf /usr/lib64/libfastcommon.*
   
4. rm -rf /usr/lib64/libfdfsclient.*
   
5. rm -rf /usr/lib/libf*
   
6. 
   
7. vim make.sh  
   
8. TARGET_PREFIX=$DESTDIR/usr/  改成 TARGET_PREFIX=$DESTDIR/usr/local
   
9. 
   
10. 
    
11. ln -s /usr/lib64/libfastcommon.so /usr/local/lib/libfastcommon.so
    
12. ln -s /usr/lib64/libfastcommon.so /usr/lib/libfastcommon.so
    
13. ln -s /usr/local/lib64/libfdfsclient.so /usr/local/lib/libfdfsclient.so
    
14. ln -s /usr/local/lib64/libfdfsclient.so /usr/lib/libfdfsclient.so

复制代码

编辑 make.sh是由于 老的FastDFS安装在/usr/local/bin下，新版改成了/usr/bin 为了兼容老版 特此更改

    5.05 的版本对应的java_client 应该使用那个？？
