执行安装redis报错undefined reference to `__sync_add_and_fetch_4\'

执行make命令时报错：

zmalloc.o: In function `zmalloc_used_memory':
 
 

  /var/lib/tcommsvr/redis-2.8.0-rc4/src/zmalloc.c:223: undefined reference to `__sync_add_and_fetch_4'
 
 

  collect2: ld returned 1 exit status
 
 

  make[1]: *** [redis-server] Error 1
 
 

  make[1]: Leaving directory `/var/lib/tcommsvr/redis-2.8.0-rc4/src'
 
 

  make: *** [all] Error 2

产生原因：

linux为32位版本。

查看方式：getconf LONG_BIT

解决办法：

make CFLAGS="-march=i686"
