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：

 

执行make命令时加参数：make CFLAGS="-march=i686"
