CPqD Software Switches

The CPqD 1.3 software switch cannot be compiled out of the box on recent versions of Ubuntu (>= 13.10 I believe).

In fact, the issue is not with the switch code itself but the netbee library it depends on which also needs to be compiled. The library cannot be compiled if your bison version is greater than 2.5. Unfortunately, since Ubuntu 13.10 the lowest available bison version is greater than 2.5, so the compilation doesn't work.

So, somehow you have to get an old version of bison on your system. There are multiple ways to do this, but I've detailed the approach I used below. 

...

1. Download the source code

   Code Block
   language text
   git clone https://github.com/CPqD/ofsoftswitch13.git

2. Go back to the specific version of Cpqd

...

1. git checkout f308c28242de57502f06d3dee80ce47ac17b6603

2. Apply the following patch

   If you save it as a file (patchfile_cpqd), then you can apply the patch as following

   Code Block
   language text
   patch -p0 < ../patchfile_cpqd

2. Build following the READ file in the directory
   
   

Now update your apt cache and install the old version of bison:

sudo apt-get update
sudo apt-get remove bison libbison-dev
sudo apt-get install bison=2:2.5.dfsg-3ubuntu1 libbison-dev=2:2.5.dfsg-3ubuntu1

Double-check you have bison 2.5 installed:

jono@ubuntu:~$ bison --version
bison (GNU Bison) 2.5
Written by Robert Corbett and Richard Stallman.
...

The mininet install script should have placed the netbee source in your home directory. I'm assuming the directory is ~/nbeesrc-jan-10-2013, but you can adapt if it's different. We'll go there and finish compiling it (credit to the mininet install script):

export NBEESRC=~/nbeesrc-jan-10-2013
cd ${NBEESRC}/src
make clean
cmake .
make
sudo cp ${NBEESRC}/bin/libn*.so /usr/local/lib
sudo ldconfig
sudo cp -R ${NBEESRC}/include/ /usr/

Now netbee is installed on the system and you can go ahead and compile the CPqD software switch. Hopefully the mininet script has already cloned the repo for you at ~/ofsoftswitch13:

cd ~/ofsoftswitch13
./boot.sh
./configure
make
sudo make install

Done.

jono@ubuntu:~$ dpctl --version
dpctl 1.3.0 compiled Jul 30 2014 22:20:00

Optional: if you care, you can upgrade bison back to the latest version. You may also want to remove the raring.list file you created earlier so there's no chance of accidentally installing old software.
