SUMO installation with Ubuntu18.04 instead of Ubuntu20.04

[Dirkjoost]

Installing Ceasiompy + Pytornado + SUMO did not work on Ubuntu20.04. I could not get it working (at least not the SUMO part). SUMO needs a downgrading of the g++ package and installing the libgfortran3, which I could not get done on ubuntu 20.04 due to incompatibility issues.

Therefore I downgraded the operating system to clean Ubuntu18.04 and get everything installed fine.

so to whomever is installing on Ubuntu, this is how I got it working on 18.04:

1. install git
2. install python 3.8 (although conda installs 3.7, not sure why...)
3. install Miniconda
   >> bash Miniconda3-latest-Linux-x86_64.sh
4. go to your preferred path and git clone https://github.com/cfsengineering/CEASIOMpy.git
5. install g++:
   >> sudo apt get install g++
6. install conda environment by
   >> conda env create -f environment.yml
7. update the ".bashrc" file with:
   alias ceasiompy='source activate ceasiompy && cd /yourPathToCEASIOMPy/CEASIOMpy/ceasiompy' alias ceasiomgui='cd /yourPathToCEASIOMPy/CEASIOMpy/ceasiompy/WorkflowCreator && python workflowcreator.py -gui'
8. activate environment through
   >> ceasiompy
9. go one directory up to install
   >> pip install -e .
10. You can check now the installation by
    >> cpacscreator
    the CPACs creator program should open up
11. PyTornado: (see https://pytornado.readthedocs.io/en/latest/) so download this file: https://github.com/airinnova/pytornado/archive/master.zip and extract it where you want it.
    a. go to the folder pytornado-master and install pytornado through:
    b. >> pip install .
    c. test by typing >> pytornado (you will get some help)
12. install libgfortran3 by
    >>sudo apt-get install libgfortran3
    N.B. this will not work with ubuntu20.04 and the reason I downgraded to ubuntu18.04
13. download the libpng12 package and place it in the right folder by
    >> sudo cp libpng12.so.0 /usr/lib/x86_64-linux-gnu/.
14. now SUMO (no documentation on installation :-( ):
    a. .download from https://www.larosterna.com/products/open-source
    b. go to the directory sumo-2.7.9/bin/
    c. open SUMO by
    >> ./dwfsumo
    d. now you can make an alias in the .bashrc file as before or type >> sudo ln -s /YourPathToSUMO/sumo-standalone-Qt4-2.7.9/sumo-2.7.9/bin/dwfsumo /usr/bin/sumo

• OS/Distribution: [Ubuntu18.04.5]
• Python version [3.8]
• CEASIOMpy version [0.0.1]
• PyTornado [0.5.4]
• SUMO [2.7.9]

Thank you for the procedure for Ubuntu18.04.

Normally the procedure to install "libpng12" solve the issue of "libgfortran3" on Ubuntu 20.04 as it is explained in the installation procedure. It is strange if it did not work for you, I manage to install it several time this way.
