Paths (which may include version numbers in directory names) used in this tutorial are taken from the university lab setup. Your paths/versions may differ.
Tested on machine: linux (Debian 5.10.46-4) - x86_64
We will use rust installation that comes with VxWorks. There should be a toolchain located in /opt/WindRiver/compilers/rust-1.60.0.0/x86_64-unknown-linux-gnu/bin directory.
Any other (system-wide) RUST installation shouldn't be necessary, however if for some reason it is, follow the standard RUST installation guide
VxWorks needs certain environment variables to run properly. Setting up these variables in terminal can be achieved by issuing command /opt/WindRiver/wrenv.linux -p vxworks.
However, in order to automate this, we can add the needed variables to the ~/.profile file in order for them to get loaded whenever terminal is opened.
To analyze which variables are needed, you can extract variables from your current setup, before and after this command:
env | sort > /tmp/before
/opt/WindRiver/wrenv.linux -p vxworks
env | sort > /tmp/after
diff /tmp/before /tmp/after
You can see the changes by analysing the diff and then apply these changes in the form of .profile file.
You can also look into what these variables look like on my system, in file profile and append this to your ~/.profile. However please note that this can differ from your setup and you can accidentally break things. Take extra care when copy-pasting the contents of PATH variable. The previous method with env and diff is preferred.
Once we prepare our project, we will need to add one more line to the ~/.profile file; it is described in the following document.
Install CLion using your favorite way and license.
Install Rust plugin for CLion.
Open settings (⌃ Control + ⌥ Alt + S) as shown in figure:
Navigate to languages & frameworks > rust > cargo location and type in /opt/WindRiver/compilers/rust-1.60.0.0/x86_64-unknown-linux-gnu/bin
Standard library should get filled automatically, if not type in /home.nfs/*****/.rustup/toolchains/stable-x86_64-unknown-linux-gnu/lib/rustlib/src/rust (replace ***** with your username)
Save the settings using OK button.
In order for the compilation in CLion to work properly, CLion needs access to the afforementioned environmental variables. There are several methods how to achieve this. One such method is launching CLion from terminal (with the profile already loaded). Different method is making a custom .desktop launcher pointing first to a script that will load ~/.profile and then launch clion with this profile. You can decide what you prefer or use a different way altogether that works with your setup.
You are now ready for your First Rust project that runs in the simulator.
