opam monorepo lock not applying global opam vars? about opam-monorepo HOT 3 CLOSED

Glad to hear it worked! My general idea would be to remove the local opam solver, since having two different implementations with rather varying behavior creates a lot of headaches.

I think the local switch solver can be emulated by reading the switches opam-repository without using the rest of the OPAM machinery.

I skimmed the code and I think it only works if you use the explicit_repo solver, not if you use the switch solver which presumably uses the variables that the switch has set.

You can see it in opam_solve.ml, only the Multi_dir_context uses opam_env (which is constructed from --global-opam-vars) as input, the Local_opam_context uses switch as input and that's just the switch state of OPAM.

Explicitly setting opam repositories did the trick, thanks! It would be great if we could update the docs to make that clearer.
