安装p4c-bm：
sudo pip install -r requirements.txt
sudo pip install -r requirements_v1_1.txt //if you are interested in compiling P4 v1.1 programs
sudo python setup.py install测试：
p4c-bmv2 -h弹出相关信息：

要求：
On Ubuntu 14.04, the following packages are required:
automake
cmake
libjudy-dev
libgmp-dev
libpcap-dev
libboost-dev
libboost-test-dev
libboost-program-options-dev
libboost-system-dev
libboost-filesystem-dev
libboost-thread-dev
libevent-dev
libtool
flex
bison
pkg-config
g++
libssl-dev以及Github中的一些工具，如thrift等，说的很详细了。
下载bmv2：
git clone https://github.com/p4lang/behavioral-model.git bmv2安装依赖：
sh install_deps.sh测试：
1. ./autogen.sh
2. ./configure
3. make
4. [sudo] make install # if you need to install bmv2make成功是这样子的：

make: *** [all] Error 2 我的解决方法是，执行：
./configure 'CXXFLAGS=-O0 -g'进入debug模式，github是这样描述的：
In 'debug mode', you probably want to disable compiler optimization and enable symbols in the binary
之后，跑样例：
make check注意，如果出现有关nanomsg的问题，需要在命令前加上sudo。
我的结果：
