Running CarSimulator on WSL (Windows Subsystem for Linux)

In case your main workstation is a Windows machine, you can run the CarSimulator in WSL.

CarSimulator was tested on WSL2 using Ubuntu 20.04

Install SocketCAN drivers

This is the hard part. Since the default Ubuntu Kernel does not have SocketCAN supported compiled in, you need to recompile the kernel.

Checkout the WSL Linux Kernel: https://github.com/microsoft/WSL2-Linux-Kernel
cd WSL2-Linux-Kernel
Switch to the best fitting tag of your current Kernel
- perform a uname -r to find out your current kernel version
cat /proc/config.gz | gunzip > .config
make prepare modules_prepare
make menuconfig
- Menu will open with your current kernel configuration
- In Network check everything regarding CAN
make modules
make -j $(nproc)
- compile the kernel
cp vmlinux /mnt/c/Users/{USER_ID}/kernel/
In your windows user directory create a file named .wslconfig
- Fill the newly created file:

[wsl2]
kernel=C:\\Users\\{USER_ID}\\kernel\\vmlinux

Compiling CarSimulator works in more or less the same way as on RaspberryPi.

Install necessary packages

# sudo apt-get install git build-essential lua5.2 liblua5.2-0 liblua5.2-dev libsocketcan-dev`

Get CarSimulator sources and build

# git clone https://github.com/AVL-DiTEST-DiagDev/car-simulator.git`
# cd car-simulator`
# make`

While still in the CarSimulator directory create a directory 'lua_configs'

# mkdir lua_configs

and put your simulation files there. For example the one from the example directory

# cp example\ luas/example.lua lua_configs

Finally start the CarSimulator:

# ./dist/Debug/GNU-Linux/amos-ss17-proj4 vcan0

Open two additional wsl console windows. One to Send and one to receive. Execute the following commands respectively.

First the receive part:

# isotprecv -s 7e0 -d 7e8 vcan0

In the second window send a message:

# isotpsend -s 7e0 -d 7e8 vcan0
01 46

You should now receive a response in the other window and see some log messages from the CarSimulator.
