参考：

安装p4c-bm：

sudo pip install -r requirements.txtsudo pip install -r requirements_v1_1.txt //if you are interested in compiling P4 v1.1 programssudo python setup.py install

测试：

p4c-bmv2 -h

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.sh2. ./configure3. make4. [sudo] make install  # if you need to install bmv2

make成功是这样子的：

Making all in testsmake[5]: Entering directory `/home/wasdns/bmv2/targets/simple_switch/tests'Making all in .make[6]: Entering directory `/home/wasdns/bmv2/targets/simple_switch/tests'make[6]: Nothing to be done for `all-am'.make[6]: Leaving directory `/home/wasdns/bmv2/targets/simple_switch/tests'Making all in CLI_testsmake[6]: Entering directory `/home/wasdns/bmv2/targets/simple_switch/tests/CLI_tests'make[6]: Nothing to be done for `all'.make[6]: Leaving directory `/home/wasdns/bmv2/targets/simple_switch/tests/CLI_tests'make[5]: Leaving directory `/home/wasdns/bmv2/targets/simple_switch/tests'make[4]: Leaving directory `/home/wasdns/bmv2/targets/simple_switch'make[3]: Leaving directory `/home/wasdns/bmv2/targets/simple_switch'make[3]: Entering directory `/home/wasdns/bmv2/targets'make[3]: Nothing to be done for `all-am'.make[3]: Leaving directory `/home/wasdns/bmv2/targets'make[2]: Leaving directory `/home/wasdns/bmv2/targets'Making all in toolsmake[2]: Entering directory `/home/wasdns/bmv2/tools'rm -f bm_p4dbg bm_p4dbg.tmpsed -e 's|@pythondir[@]|/usr/local/lib/python2.7/dist-packages|g' ./bm_p4dbg.in >bm_p4dbg.tmpchmod +x bm_p4dbg.tmpchmod a-w bm_p4dbg.tmpmv bm_p4dbg.tmp bm_p4dbgrm -f bm_CLI bm_CLI.tmpsed -e 's|@pythondir[@]|/usr/local/lib/python2.7/dist-packages|g' ./bm_CLI.in >bm_CLI.tmpchmod +x bm_CLI.tmpchmod a-w bm_CLI.tmpmv bm_CLI.tmp bm_CLIrm -f bm_nanomsg_events bm_nanomsg_events.tmpsed -e 's|@pythondir[@]|/usr/local/lib/python2.7/dist-packages|g' ./bm_nanomsg_events.in >bm_nanomsg_events.tmpchmod +x bm_nanomsg_events.tmpchmod a-w bm_nanomsg_events.tmpmv bm_nanomsg_events.tmp bm_nanomsg_eventsmake[2]: Leaving directory `/home/wasdns/bmv2/tools'make[2]: Entering directory `/home/wasdns/bmv2'make[2]: Leaving directory `/home/wasdns/bmv2'make[1]: Leaving directory `/home/wasdns/bmv2'

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 
    
      for instructions.make[3]: *** [packet.lo] Error 1make[3]: Leaving directory `/home/wasdns/behavioral-model/src/bm_sim'make[2]: *** [all-recursive] Error 1make[2]: Leaving directory `/home/wasdns/behavioral-model/src'make[1]: *** [all-recursive] Error 1make[1]: Leaving directory `/home/wasdns/behavioral-model'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：

还是出现了一个Error，查看日志信息：

cd testsvim test-suite.log

日志如下：

应该是thrift的问题，该问题还在解决中。
