Did you execute git submodule update --init --recursive scripts?

I use following commands to install all modules Ubuntu Trusty:

sudo apt-get update
sudo apt-get install python-dev python-pip git make -y
sudo pip install scapy thrift networkx ctypesgen

git clone https://github.com/p4lang/ptf
cd ptf
sudo python setup.py install
cd ..

git clone https://github.com/p4lang/p4c-bm.git p4c-bmv2
cd p4c-bmv2
sudo pip install -r requirements.txt
sudo python setup.py install
cd ..


git clone https://github.com/p4lang/behavioral-model.git bmv2
cd bmv2
./install_deps.sh
./autogen.sh
./configure --with-pdfixed
make
cd ..

git clone https://github.com/p4lang/switch
cd switch
git submodule update --init --recursive
./autogen.sh
./configure --with-bmv2 --with-switchsai
 make

Kind regards,
Jon
