linux - 安装memcached却编译出错

已经安装了libevent
yum install libevent-devel
并且安装了一些编译工具
yum -y install gcc gcc-c++ libstdc++-devel

按照官方提示使用以下安装方法

wget http://memcached.org/latest
tar -zxvf memcached-1.x.x.tar.gz
cd memcached-1.x.x
./configure && make && make test && sudo make install

但当make的时候报错，信息如下：

gcc -std=gnu99 -DHAVE_CONFIG_H -I.    -fprofile-arcs -ftest-coverage -g -O2 -pthread -pthread -Wall -Werror -pedantic -Wmissing-prototypes -Wmissing-declarations -Wredundant-decls -MT memcached_debug-slabs.o -MD -MP -MF .deps/memcached_debug-slabs.Tpo -c -o memcached_debug-slabs.o `test -f 'slabs.c' || echo './'`slabs.c

怎么才能成功安装memcached呢？

    The problem has been solved because the Makefile has -Werror, which prevents warnings from being compiled. Just modify the Makefile and remove the -Werror parameter. -Werror means a warning is an error, that is, if a warning is generated during the compilation process, the compilation will not pass. The source code of memcached may not be written rigorously enough, and a warning appears.
    Thanks @大书 for the tip.
