Ubuntu24.04 error: cannot load such file -- net/smtp (LoadError)

[chhtz]

Not sure if that is already on the agenda. I'm trying to bootstrap a project on Ubuntu24 using:

wget http://rock-robotics.org/master/autoproj_bootstrap
ruby autoproj_bootstrap git ${some bootstrap url}

Full output (HOME_DIR and BOOTSTRAP_DIR are valid directories of course):

Are there any known workarounds? I tried manually installing

gem install -i ~/.local/share/autoproj/gems/ net-smtp

Or adding that to autoproj's Gemfile without success.

I guess I don't need any smtp-support, but probably this won't be the only issue.

Can you please try with https://github.com/rock-core/autoproj/raw/refs/heads/master/bin/autoproj_bootstrap instead?

[g-arjones]

Nevermind... There's a PR still pending on autobuild.

[chhtz]

Thanks for the fast response!
It is indeed still the same error (except for some line numbers). I assume you mean this PR rock-core/autobuild#127?
Can I test locally with a fork/branch of autobuild?

[planthaber]

As far as I remember you can bootstrap with https://rock-robotics.org/autoproj_bootstrap-dev to get locally checked out versions of autoproj/autobuild

[chhtz]

Nice that works! (I downloaded that and replaced the branch name of autobuild inside the script). And in fact bootstrapping succeeds, but aup fails at some point with:

[...]
Command failed
the 'binding_of_caller' osdep refers to another osdep, 'ruby-dev', which does not seem to exist: Autoproj::OSPackageResolver::InvalidRecursiveStatement

I could resolve this by copying:

cp ./autoproj/remotes/orocos.toolchain/orocos.osdeps-ruby3{0,2}

After that, I think I only have dependency issues related to the actual bootstrap (e.g., not finding libqwt5-qt4-dev ...), i.e., from my side I'm fine with closing this once the related PR is merged.

@chhtz Can you give a few more details on how you got that script to run? I changed the branch name in default_gemfile_contents, but when I run it it just picks up the official release gem again.

[chhtz]

This is my line 271 in autoproj_bootstrap-dev:

                 "gem \"autobuild\", git: \"https://github.com/rock-core/autobuild.git\", branch: \"run_workflows_on_ruby3\"",

And afterwards I called

ruby autoproj_bootstrap-dev git ${some bootstrap url}

Just retested and it still works (to actually aup+amake, I had to adapt several package sets).

[ndahn]

Ahhh, I had an .autoproj folder that had the version cached. Thanks!

[ndahn]

FYI, one major issue is that recent versions of ruby abandoned File.exists? in favor of File.exist? (no s)...

[chhtz]

@ndahn I made PRs for most (?) required changes. All necessary overrides should be in the relatively new dfki.ric package set, so this should work in an otherwise empty project:

package_sets:
  - github: dfki-ric/dfki-ric-package_set
layout:
  - dfki.ric
  - rock.cpp
  - rock.core
ignored_packages:
  - gui/vizkit
  - gui/qgv
  - gui/rock_replay
