Compilation issue

[Erik Martin-Dorel]

Dear developers of Certicoq,

I've tried compiling Certicoq master in order to play with the plugin; but I wasn't able to proceed, maybe because of some linking issue…
I've tried using the dependencies from the Git submodules with different versions of OCaml and Coq in ({4.05.0, 4.06.1, 4.07.0+flambda} × {8.8.1, 8.8.2}), but ended up with the error:

File "./CertiCoq.v", line 3, characters 0-33:
Error:
Anomaly "cannot find tmExistingInstance in module Template.TemplateMonad.Extractable."
Please report at http://coq.inria.fr/bugs/.

I've not investigated further, but FYI I paste below a sample Dockerfile I've been using, with OCaml version 4.06.1 and Coq version 8.8.1 (as suggested in the README.md).
Do you think this issue is easy to solve?

Kind regards, Erik

Hi Erik,
Thank you for opening this issue. There is some linking issue with MetaCoq at the moment. I have created a rollback branchopam-rollback that is compatible with the opam version of TemplateCoq (coq-template-coq.2.1~beta3). Please let us know if that doesn't work for you! We'll update this issue once the master branch is fixed.

Indeed I hadn't checked that the plugin compiled correctly, I fixed a bunch of things related to the extracted code and it builds correctly now, for me. Can you check @osavaryb ? You might want to remove plugin/extraction/* and theories/Extraction/*.ml (then resurrect things there) first.

This is fixed, master should now compile, please reopen if you still have problems after pulling.
