memcache编译安装（cygwin环境）
来源：程序员人生 发布时间：2015-05-05 07:54:58 阅读次数：4710次
最近尝试编译libevent，可是1直都编译不成功，所有，研究了1下memcahe的编译进程，希望能有所帮助（memcache的底层就是libevent）。
首先，在官网上下载memcache的源码包，我使用的是1.4.24这个版本（http://memcached.org/）
不多说，下载以后固然得tar xvf memcached⑴.4.24.tar.gz，然落后入memcached⑴.4.24的源码目录，接下来就能够开始编译了。
1.configure阶段
直接运行./configure,发现检测不通过，报错是缺少了libevent的库
checking for libevent directory... configure: error: libevent is required. You can get it from http://www.monkey.org/~provos/libevent/
If it's already installed, specify its path using --with-libevent=/dir/
libevent我已是配置了，指定libevent目录
./configure --with-libevent=/usr/local/libevent
......
configure: creating ./config.status
config.status: creating Makefile
config.status: creating doc/Makefile
config.status: creating config.h
config.status: executing depfiles commands
OK，成功
2.make && make install阶段
直接履行make，本来以为已没甚么问题了，结果却是报错。
memcached.c:4810:13: 毛病：数组下标类型为‘char’ [-Werror=char-subscripts]
if ((ever[2] == '1' || ever[2] == '2') && !isdigit(ever[3])) {
产看源码，这段代码的功能是检测libevent版本，删掉“&& !isdigit(ever[3])”可以编译成功，但此时功能有问题，还应当把return false给屏蔽掉
再次履行make，成功了。
脑残的下1步：make install
3.启动&简单测试
启动memcache，这里对启动参数就不详细说了，默许端口是11211
ACER1@lizhibin /memcache/memcached⑴.4.24
$ which memcached.exe
/usr/local/bin/memcached.exe
ACER1@lizhibin /memcache/memcached⑴.4.24
$ memcached.exe -m 100
使用telnet进行连接
telnet 127.0.0.1 11211
