Dear Anton, the Undefined function ASDF/INTERFACE::OPERATION-FORCED called with arguments (#<LOAD-OP>) errors are due to using old variants of SLIME. I opened a merge request for some backward-compatibility support: https://gitlab.common-lisp.net/asdf/asdf/merge_requests/64
A lot of the MAKE-OPERATION errors seem to be related to the abuse of ASDF internals by asdf-system-system-connections. I opened a PR against it on github, but Gary King seems not to reply to his email. I hope his health is OK, but maybe we should fork the project onto sharplispers. https://github.com/gwkkwg/asdf-system-connections/pulls Gary, are you listening? Xach, what's the process to become member of sharplispers and/or get some project cloned there? https://github.com/sharplispers > https://common-lisp.net/project/cl-test-grid/asdf/asdf-diff-51.html —♯ƒ • François-René ÐVB Rideau •Reflection&Cybernethics• http://fare.tunes.org The world is a comedy to those that think; a tragedy to those that feel. — Horatio Walpole, 4th Earl of Orford (1717–1797)
