memcache編譯安裝（cygwin環境）

最近嘗試編譯libevent，可是1直都編譯不成功，所有，研究了1下memcahe的編譯進程，希望能有所幫助（memcache的底層就是libevent）。
首先，在官網上下載memcache的源碼包，我使用的是1.4.24這個版本（http://memcached.org/）
不多說，下載以后固然得tar xvf memcached⑴.4.24.tar.gz，然落后入memcached⑴.4.24的源碼目錄，接下來就能夠開始編譯了。
1.configure階段
直接運行./configure,發現檢測不通過，報錯是缺少了libevent的庫
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目錄
./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階段
直接履行make，本來以為已沒甚么問題了，結果卻是報錯。
memcached.c:4810:13: 毛病：數組下標類型為‘char’ [-Werror=char-subscripts]
if ((ever[2] == '1' || ever[2] == '2') && !isdigit(ever[3])) {
產看源碼，這段代碼的功能是檢測libevent版本，刪掉“&& !isdigit(ever[3])”可以編譯成功，但此時功能有問題，還應當把return false給屏蔽掉
再次履行make，成功了。
腦殘的下1步：make install
3.啟動&簡單測試
啟動memcache，這里對啟動參數就不詳細說了，默許端口是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進行連接
telnet 127.0.0.1 11211
