测试平台：DigitalOcean VPS ubuntu14.04 x64, strongswan5.2.2

运行以下命令请使用root权限

一：安装strongswan

由于ubuntu软件仓库中strongswan版本较低，因此从官网源码编译安装

apt-get install build-essential     #编译环境
aptitude install libgmp10 libgmp3-dev libssl-dev pkg-config libpcsclite-dev libpam0g-dev     #编译所需要的软件

# This file contains some work-in-progress bottom-up design work for the GLR.
# All types and operators introduced are prefixed with GLR, so there are no
# conflicts with those in core (the GLR prefix has even been used where there
# isn't anything in core to conflict with, to make clear what's being added).
# There's no syntax sugar, but rather explanations of what some syntax will
# desugar to are included. The various MAIN subs do tests to check correctness
# and various benchmarks to compare with what we have in Rakudo today.

Take a Rakudo repo. Place the above file in src/json.nqp. Build it like this:

nqp --vmlibs=perl6_group,perl6_ops --target=pir --combine src/json.nqp src/gen/main-version.nqp > src/json.pir

Then you can do:

install\bin\parrot.exe src\json.pir -e "say 42"

Which will dump the parse tree as JSON.
