libmemcache 1.0.11 & 1.0.12 have problem !

我在 CentOS 5.8 x86_64 上面將 php 5.2 升級到 5.3 去
先升級 memcache 到 1.4.15, libmemcached 到 1.0.12(原本是 0.x)
到 php 5.3 要用 pecl 安裝 memcached 會出現下面問題

# /usr/local/php5/bin/pecl install memcached

上網查了一下有這問題的人不多
因為之前有先測試過升級到 php 5.3 都沒問題
於是想說從 libmemcached 下手看看
果真是新的版本問題

提供安裝步驟供參考：

安裝 memcached

# wget http://memcached.googlecode.com/files/memcached-1.4.15.tar.gz
# ./configure
# make && make install

啟動 memcached

/usr/local/bin/memcached -d -u root -m 128 -p 11211

安裝 libmemcached

# http://download.tangent.org/libmemcached-1.0.10.tar.gz
#./configure --with-memcached
# make && make install

php 5.3 安裝

./configure --prefix=/usr/local/php5 \
--with-apxs2=/usr/local/apache2/bin/apxs \
--with-mysql=/usr/local/mysql \
--with-mysqli=/usr/local/mysql/bin/mysql_config \
--with-config-file-path=/usr/local/php5 \
--enable-mbstring --enable-ftp --with-zlib --with-regex=php \
--with-xmlrpc \
--with-gd --enable-gd-native-ttf \
--enable-exif \
--with-jpeg-dir=/usr/lib --with-png-dir=/usr/lib \
--with-freetype-dir=/usr/lib \
--with-xpm-dir=/usr/lib \
--with-gettext \
--enable-soap \
--with-pdo-mysql=/usr/local/mysql \
--with-mhash \
--with-mcrypt \
--with-openssl \
--with-curl \
--enable-sockets \

安裝 pecl 的 memcached 套件

/usr/local/php5/bin/pecl install memcached
記得要在 php.ini 加上檔案的位置
