最近做毕设，大致了解了下 NOX网络控制器 和openflow相关知识。

nox是openflow网络中处于 控制层 的一种控制器。其代码主要由C++编写 ，官方网站中的nox-classic为c++与python混写的旧版nox ，新版的nox为了追求高效的性能而放弃python，完全只支持c++。

我们项目对性能没有过高要求，故选择了便于开发组件的nox-classic

要搭建一个实验环境，首先我们需要安装nox

git clone https://github.com/noxrepo/nox-classic
cd ./nox-classic
./boot.sh
./configure
make
sudo make install

简单说来就这几行命令，每一步都不报错的话就安装成功了。。。

而实际情况是， nox-classic版本已经许久没有维护，故会有这样那样的报错

这里说几个我遇到的：

1. boot.sh 提示

src/tests/../Make.vars:56: `pkglibdir' is not a legitimate directory for `SCRIPTS'
src/tests/Makefile.am:1:   `src/tests/../Make.vars' included from here
src/utilities/../Make.vars:56: `pkglibdir' is not a legitimate directory for `SCRIPTS'
src/utilities/Makefile.am:1:   `src/utilities/../Make.vars' included from here
autoreconf: automake failed with exit status: 1

这时可以使用本patch

diff --git a/src/Make.vars b/src/Make.vars

+pkgdata_SCRIPTS = $(NOX_RUNTIMEFILES) $(NOX_PYBUILDFILES)
 BUILT_SOURCES  = $(NOX_PYBUILDFILES)

2. configure 时提示swig库必须大于1.3时 可以卸载当前系统版本的swig  并到swig官网下载一个1.3.X版本的swig

3.make 时 提示

error: 'ptrdiff_t' was not declared in this scope

可以使用这个patch

diff --git a/src/nox/lib/netinet/netinet_wrap.cc b/src/nox/lib/netinet/netinet_wrap.cc
index 0e89f2b..c49571b 100644

剩下的应该都很好解决了

然后安装一个mininet以模拟有openflow交换机的网络
