This page will guide you through the installation process of the Lab:

  1. Install  Ubuntu 18.04.3 LTS.

    https://releases.ubuntu.com/18.04/                                                                     or

    https://tutorials.ubuntu.com/tutorial/tutorial-create-a-usb-stick-on-ubuntu     or

    https://tutorials.ubuntu.com/tutorial/tutorial-create-a-usb-stick-on-windows

  2. Clone our cpm software repository with:

    git clone https://github.com/embedded-software-laboratory/cpm_lab software


  3. Prepare to run our installation script by getting a license.dat-file for the RTI DDS Connext Service (ask your supervisor if you are a student or get into contact with RTI)
  4.  Run our script to install all necessary components.  In the software folder you have just cloned you find install.sh.

    OpenCV 4.0 for the Indoor Positioning System

    Basler Pylon 5 for the Indoor Positioning System and lab camera

    Change DDS Domain

    If you want to change the DDS Domain later, change the corresponding variable DDS_DOMAIN in /etc/profile.d/rti_connext_dds.sh.

    The following domain IDs are used in the CPM Lab:

    Domain IDPurpose
    21Lab (main computer, NUCs, vehicles)
    61-66Student computers

    Change RTI license file

    If you want to update your license file, change the file at: /opt/rti_connext_dds-6.0.0/rti_license.dat
  5. Reboot your PC.

  6. Optional:
    Setup MATLAB. As a student from RWTH, you can do this with a MathWorks account following these instructions.
    For RTI DDS: Download the DDS Support Package for MATLAB and install the toolbox. The native DDS addon that ships with MATLAB versions from 2021a only supports Simulink. If you are going to code in MATLAB, install the corresponding package from the link.

    To use MATLAB  with eProsima, look here.

    Make sure to create a symbolic link to the MATLAB binary during or after the setup!

  7. Run the build script.

Troubleshooting

  • If you have problems during the building process, try starting over again with

    cd ~/software/
    git pull 
    git clean -xdf 
    ./build_all.bash
  • If you ever run build_all.bash  as root , you might run into a lot of permission denied  errors. You need to delete all files and folders that were created and rerun as your usual user.

  • If you recieve an error like "dds/someheader.h" not found, run the command "rtiddsgen", which should build the neccesarry cpp-files
  • If you recieve an error regarding timing issues of unittests, run

    git clean -xdf
    ./build_all.bash

    again. This error occurs often in VM.
