What does it mean when
opam pin add coq.8.13.1 fails with
Error: Could not retrieve /home/runner/work/fiat-crypto/fiat-crypto/coq.8.13.1?
hard to know opam's black magic, I'd say the first thing to look into is if the right
--kind argument for opam pin was used.
--kind? The full log is at https://github.com/mit-plv/fiat-crypto/runs/2503870392, btw. Does
coq.8.13.1 not make sense? I think it worked fine when I did
opam pin add coq 8.13.1, but
opam pin add coq dev does not work...
man opam pin
you want a dot in
best is to use
--kind tho, otherwise you get surprises quite often
What should I be passing to
git? And perhaps the instructions at https://coq.inria.fr/opam-using.html suggesting
opam pin add coq 8.13.1 should be updated to include
--kind? Or is it not necessary there?
If you want to pin the version only, then pass the version kind, not?
Maybe it should be updated, the problem with omitting kind is that then the kind of pin that opam will select will depend on what the contents of
pwd are, env variables, and a bunch of other factors.
This is new in opam 2.0 so you will find plenty of examples omitting it, but in fact it was added to resolve the problems in Opam 1.2 pin, but for compat
opam pin still tries to guess the kind if the arg is not present
+1 for updating instructions, opam should just stop guessing since it never seems to guess the right thinu
