Answer 1

如果你用的是Ubuntu/Debian系统,执行sudo apt-get install php5-mcrypt就行了.
如果你是自己编译的PHP,则需要通过PHP提供的phpize来添加扩展:

#先安装mcrypt开发包(包含头文件和库文件),这样就不需要自己编译mcrypt库了
sudo apt-get install libmcrypt-dev
/usr/include/mcrypt.h #头文件
/usr/lib/libmcrypt.so #动态库
/usr/lib/libmcrypt.a  #静态库

#用phpize编译php5-mcrypt扩展
cd php-src/ext/mcrypt
/opt/php/5.6/bin/phpize #生成configure
./configure --with-php-config=/opt/php/5.6/bin/php-config #生成Makefile
make && make install #编译安装

根据返回的错误提示 make[2]: gaa：命令未找到
