在更新OS X之后,我发现很多我以前构建的扩展已经消失;(
现在我正在尝试编译memcached.so,结果我有很多错误;(
我安装了XCode命令行工具并运行如下编译：
sudo pecl install memcached
结果：

make: *** [php_memcached.lo] Error 1
ERROR: `make' failed
有什么办法吗？谢谢.
解决方法:
在2.1.0版中,修补了文件php_libmemcached_compat.h
cd / private / tmp / pear / temp / memcached
在php_libmemcached_compat.h中添加一行：
typedef const struct memcached_server_st * memcached_server_instance_st;
sudo ./configure
sudo make
sudo make install
而已.
