# wget http://launchpadlibrarian.net/66527034/libmemcached-0.48.tar.gz# cd libmemcached-0.48# ./configure --prefix=/usr/local/libmemcached  --with-memcached# make && make install

Notes for installation:

1. Do not forget to install it. -- with-memcached. Otherwise, you will be prompted.
Checking for memcached... no
Configure: error: "cocould not find memcached binary"

2. Is your memcached above 1.2.4? If not, you will be prompted

/Home/zhangy/libmemcached-0.42/clients/ms_thread.c: 225: undefined reference to '_ sync_fetch_and_add_4'

Solution is -- disable-64bit CFLAGS = "-O3-march = i686", if you don't need this 64-bit long data, I want php to expand memcached, memcache will be no difference, it doesn't make much sense to install memcached.

# wget http://pecl.php.net/get/memcached-2.2.0.tgz# cd memcached-2.2.0# /usr/local/webserver/php/bin/phpize# ./configure --enable-memcached --with-php-config=/usr/local/webserver/php/bin/php-config --with-libmemcached-dir=/usr/local/libmemcached --disable-memcached-saslchecking for sasl/sasl.h... noconfigure: error: no, sasl.h is not available. Run configure with --disable-memcached-sasl to disable this check# make && make install
