Main Computer Setup

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

Install Ubuntu 18.04.3 LTS.

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
Create a folder called dev in your home directory
Clone our cpm software repository into your dev-folder by typing:
```
cd ~/dev
git clone https://github.com/embedded-software-laboratory/cpm_lab.git
```
you have to enter your git username and password
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)

Run our script to install all necessary components. In the software- folder you have just cloned you find 'install.sh'.

todo	full installation	simulation setup only
run	cd software/ sudo bash install.sh	cd software/ sudo bash install.sh --simulation
What will it install?	Unbuntu packages	Unbuntu packages
	Joystick/ Gamepad	Joystick/ Gamepad
	RTI DDS Connext	RTI DDS Connext
	RTI ARM
	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, go to /etc/profile

Currently at the CPM Lab the IDs are the following

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

Reboot your PC to avoid running source /etc/profile.d/rti_connext_dds.sh in every terminal you open.
Run the build script.
full setup only simulation setup
./build_all.bash
./build_all.bash --simulation

Troubleshooting

If you have problems during the building process, try starting over again with
```
cd ~/dev/software/
git pull 
sudo 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 the ./build_all.bash script again. This error occurs often in VM.
