编译vpp文档

使用virtualenv虚拟环境，编译vpp文件
1.virtualenv虚拟环境安装：

$ sudo python -m pip install --user virtualenv 
$ sudo python -m virtualenv env
$ sudo source env/bin/activate
$ sudo pip install -r docs/etc/requirements.txt

pip install -r docs/etc/requirements.txt的时候，如果出现某个软件安装失败，
需要手动安装：
Cannot uninstall ‘pyparsing’. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.

下面软件是安装时候出现异常，需要手动安装的

sudo pip install -I pyparsing==2.3.0
sudo pip install -I packaging==18.0
sudo pip install -I requests==2.21.0

2.编译html文件

(env) [ych@localhost vpp]$ cd docs/
(env) [ych@localhost docs]$ 
(env) [ych@localhost docs]$ make html

编译vpp

# if vpp<08.10
make install-dep
make bootstrap
make build        # or `make build-release`

# vpp 08.10+ (cmake)
make install-dep
make install-ext-deps
make build        # or `make build-release`

make install-dep和 install-ext-deps主要是安装编译需要的依赖库
make build 编译出来的版本包含了调试符号，可用于调试debug用
make build-release 编译已经发布出来的版本，进过了优化，不会创建任何调试符号
