Hey all,

I've been directed to take a look at opam-debian-switch to identify ways to contribute to the project, and I've been trying to replicate the workflow described in the Readme.

The first thing I noticed is that I was unable to run make because it seems that there are some new packages added to the debian repo that have not
been added to the pkgmap.json, so I made those changes. Once, I was able to run make, I ran into a different error.

When running setup.opam.sh as builder, I get an error at the step of installing from opams-to-install.txt. It seems to be unable to install ocaml-base-compiler:

[ERROR] Package conflict!
* No agreement on the version of ocaml-base-compiler:
- ocaml-base-compiler
- (invariant) -> ocaml-base-compiler = 4.13.1
You can temporarily relax the switch invariant with `--update-
invariant'
* Incompatible packages:
- ocaml-base-compiler
- (invariant) -> ocaml-system = 4.13.1

What should I do about this error? Is there something wrong with ocaml- base-compiler rather than opam-debian-switch?

Is there a mistake I could have made in the workflow? I tried schroot with both sid and stable, and I got the same error twice.

My guess is that I shouldn't just mark ocaml-base-compiler with "!".

Best,
Silas

I'm so sorry, I just only saw your e-mail.

I must admit opam-debian-switch is a bit hackish at the moment... I
updated it the day before yesterday, and it mostly works. You just have
to apt-install xdot in the chroot manually, and remove ppx-globalize
from opams-to-install before running setup-opam.sh.


Cheers,
