回顾下先前的安装笔记：
PHP5不重新编译，如何安装自带的未安装过的扩展，如soap扩展？
#下载 Swoole-1.8.10后，开始编译#
cd /Users/jianbao/Downloads/swoole-src-1.8.10-stable
/usr/local/php/bin/phpize
./configure --with-php-config=/usr/local/php/bin/php-config --enable-async-mysql
sudo make install
修改 php.ini，加入extension=swoole.so，开启swoole扩展
【报错】
$ sudo /usr/local/php/bin/phpize

PHP Api Version: 20131106

Cannot find autoheader. Please check your autoconf installation and the
$PHP_AUTOHEADER environment variable. Then, rerun this script.
【解决】
brew install autoconf
ln -s /usr/local/Cellar/autoconf/2.69/bin/autoconf /usr/local/bin/autoconf
ln -s /usr/local/Cellar/autoconf/2.69/bin/autoheader /usr/local/bin/autoheader
