Error on make image

[fabiosvm]

I'm trying to add my own programming language called Hook (https://github.com/fabiosvm/hook-lang) to this riju project. Reading the guides, I found the entry of new languages friendly. That's true?

I created a langs\hook.yaml file and following the guide when running the command: make image shell I=admin I got the following error:

Can someone help me?

I'm in Ubuntu 20.04 on VPS (DigitalOcean)

Yes, this is a known problem, and I apologize. I made some decisions in the design of Riju which, in retrospect, made it very hard to maintain the project. One of them was using non-LTS Ubuntu versions in the base images. As a result of this, much of the build tooling has rotted, and it's impossible even for me to add new languages without doing extensive manual hacks.

Unfortunately, in order to unblock adding new languages again, significant reworking of the build system is needed. I plan to do this in the medium term future - it's my current focus for the part of my time dedicated to improving the maintainability of my open-source projects - but I'm not working on it just this moment.
