sudo sh -c "echo 'deb http://www.lrde.epita.fr/repo/debian/ stable/' >> /etc/apt/sources.list"
sudo apt update
sudo apt install spot libspot-dev spot-doc
sudo apt install python3-spot # For python3 support

Install necessary dependencies:

sudo apt install python-pip
pip install six
pip install matplotlib
pip install numpy
sudo apt install python-tk
pip install networkx==1.11
pip install pyyaml
pip install pp # Optional

Download and unpack ltl2dstar

Download from: https://www.ltl2dstar.de/
Unpack ltl2dstar
Navigate to the ltl2dstar folder

Run the following lines in shell:

mkdir build
cd build/
cmake -DCMAKE_BUILD_TYPE=Release ../src
make

Optionally add the binary to folder in PATH

For example:

mkdir ~/bin
cp ltl2dstar ~/bin/
echo 'export PATH="$PATH:$HOME/bin"' >> ~/.bashrc

Set $PYTHONPATH to include the location of the lomap library:

Run the following line in shell:

export PYTHONPATH="${PYTHONPATH}:/path/to/lomap"

Optionally make this setting persistent:

echo 'export PYTHONPATH="${PYTHONPATH}:/path/to/lomap"' >> ~/.bashrc

Test if the setup worked properly:

Navigate to /lomap/lomap/tests
Run any of the Python test files
- Ex. python test_automata.py

Common Issues:

   ImportError: No module named lomap.classes

Problem: The lomap library is not in the path variable PYTHONPATH

Possible Solution: Manually add lomap to your Python directory

cd <lomap_directory>
export PYTHONPATH="$PYTHONPATH:$PWD"

   File "/usr/bin/pip", line 9, in <module>
   from pip import main
   ImportError: cannot import name main

Problem: Wrong version of pip (are using Python 3 pip)
Solution: Run commands with pip2

AttributeError: 'Graph' object has no attribute 'nodes_iter' (or other graph issues)

Problem: Wrong version of networkx installed
Solution: Uninstall networkx and install networkx1.11 (see above)
