Missing dependencies while building ruby-3.4.3 on Ubuntu 24.04

[damisul]

Just installed Ubuntu 24.04.2 LTS of a new desktop.

Installed asdf 0.16.7 using binary, added ruby plugi.

Tried to build ruby 3.4.3 and got several compilation errors due to missing dependencies:

• zlib1g-dev
• libffi-dev
• libyaml-dev

After few iterations of trying to build, checking logs and installing missing dependencies I've finally got ruby installed, but I believe good version manager should install such dependencies automatically.

Probably duplicate of #386

Actually it's already document in Install section of the README : https://github.com/asdf-vm/asdf-ruby?tab=readme-ov-file#install

Please make sure you have the required system dependencies installed before trying to install Ruby.

Yes, I've also found this later. But again, I believe it would be better if version manager handled it itself. For example rvm fetches all required dependencies automatically.

So I think it should be handled upper in the stack : at asdf level and not at plugin level.

I disagree that a plugin should handle automatic package installation because ASDF manages tools, not packages. The premise behind it is that installing tools won't change your system state, except for the tools added to the PATH.

If plugins begin to change system state and packages they become more likely to introduce problems at system level.
