Building vrouter

TurnToJPG -->

Preparation

First we should get repo, while this little kit has been banned via GFW, thus we should use DO machine for getting it down and ssh to local machine.

$ mkdir ~/bin
$ PATH=~/bin:$PATH
$ curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
$ chmod a+x ~/bin/repo
$ tail ~/.zshrc
# Add our own bin/ folder for using different tools:    
export PATH="$PATH:$HOME/bin"

Now we could use repo.

Oops, git is old!

The default version of git is too old in CentOS, thus we have to upgrade it. , repo needs git version newer than 1.7.2, or you won’t get any results from github.

~% git --version
git version 1.7.1

Install necessary packages:

$ sudo yum install curl-devel expat-devel gettext-devel openssl-devel zlib-devel gcc perl-ExtUtils-MakeMaker

Now build and install git via:

$ sudo mkdir -p /usr/local/git
$ wget https://www.kernel.org/pub/software/scm/git/git-1.9.4.tar.gz
$ tar xzvf git-1.9.4.tar.gz
$ cd git-1.9.4
$ make prefix=/usr/local/git all
$ sudo make prefix=/usr/local/git install
$ echo "export PATH=/usr/local/git/bin:$PATH">>~/.zshrc
$ source ~/.zshrc
$ git --version
git version 1.9.4

Now the git is already the newer version, we could use it together with repo.

Sync Repository

Unfortunately we have been blocked by GFW, so we have to enable little tool proxychains:

$ git clone https://github.com/rofl0r/proxychains-ng.git 
$ cd proxychains-ng
$ ./configure --prefix=/usr
$ make
$ sudo make install
$ sudo make install-config
$ sudo vim /etc/proxychains.conf
# defaults set to "tor"
#socks4 	127.0.0.1 9050
socks5 	127.0.0.1 1395

Now we could use proxychains for syncing the repositories, simply init the repo via:

$ cd /home/xxx.xxxxx/Code/Vrouter_repo
$ proxychains4 repo init -u git@github.com:Juniper/contrail-vnc -m vrouter-manifest.xml

Now sync the repository via:

$ proxychains4 repo sync

Build

After syncing the code, we could finally build this repository, build it via;

$ scons vrouter

Seems boost is pretty old on CentOS 6.6, thus we have to manually compile boost on our system.
Since some packages are pretty old on CentOS, I switched to the ubuntu for developing.
