p4c-bm arguments
positional arguments:
source A source file to include in the P4 program.
optional arguments:

安装bmv2：
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 bmv2
make成功是这样子的：

当make不成功的时候，一般是报.lo的错误，比如：
g++: internal compiler error: Killed (program cc1plus)
Please submit a full bug report,
with preprocessed source if appropriate.
See <file:///usr/share/doc/gcc-4.8/README.Bugs> for instructions.

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：

应该是thrift的问题，该问题还在解决中。
