3 years ago ppx_variants_conv is not compatible with the ocaml version installed (4.13.1) Currently xen-api is compatible with ocaml 4.10 and 4.11.
When creating the switch, please use ocaml-base-compiler.4.10.1, the rest of your notes follow the ci which is quite convoluted, but should work. Let us know if you have other issues

3 years ago Thanks for the fast reply psafont!
I missed that, thanks! I should definitely be using 4.10.1 regardless, but I'm still hitting the issue. Here's the recent trace back:
I see the path /home/victor/.opam/ocaml-base-compiler.4.10.1/ a lot in there, so I think I'm using the right compiler now.
Here's some extra debug info, hopefully it helps.

2 default https://opam.ocaml.orgIf there's a better way to be able to use the xe package, I'm definitely open to change directions with this. The only reason I went this route, was I was following your guy's GitHub Action for building this.

3 years ago I also just tried with both ocaml-base-compiler.4.10.2 and ocaml-base-compiler.4.11.2, and they gave the same error. I'm switching like so:
opam switch create ocaml-base-compiler.$VERSION
eval $(opam env --switch=ocaml-base-compiler.$VERSION --set-switch)
opam pin --yes add . --no-action
opam --yes depext --yes -u $PACKAGES
opam install $PACKAGES --yes --deps-only --with-test -vAlso one thing I noticed, when I run opam update && opam upgrade, I see this output:
The following packages are not being upgraded because the new versions conflict with other installed packages:
- io-page.2.4.0
∗ io-page-unix.2.3.0 is installed and requires io-page = 2.3.0
However, you may "opam upgrade" these packages explicitly, which will ask permission to downgrade or uninstall the conflicting
packages.Could it maybe be my conflicts are getting handled differently than expected?

3 years ago So one details that's not evident from the github action is that before trying to install packages into the opam switch, the default repository must be removed for the version resolution to work.
Adding the step
opam repo remove defaultafter adding the xs-opam repository should work.
If there's a better way to be able to use the xe package, I'm definitely open to change directions with this.
I don't think so, we don't provide a statically packaged xe binary

3 years ago Yep that did it! Thanks for your help! It took me a bit to figure out I was forgetting to pin, and jumped straight to running depext, but it's working now. I have the program at ./_build/install/default/bin/xe.
Now that I have a minimal command list to build, I'd be down to (heavily) clean it up and open a PR to your README here. Is this something you guy's would consider accepting? Or do the steps change too drastically between OS's?

Yeah, I'd love to get the readme in a better shape, the same with https://github.com/xapi-project/xs-opam

3 years ago Just opened a PR here! I have no clue what to add for the xs-opam side of things, but hopefully the instructions are useful for xen-api at least. Thanks again for your help @psafont!
Fresh install of Ubuntu Desktop 20.04, I'm trying to run
xewith the xen hypervisor. I can't find a way to download it directly, so I think you build it from source? I haven't used opam before this attempt, so hopefully it's an easy fix.Commands from my notes:
This last command always fails with "Error: Unbound value Lexer.keyword_table"
Output of opam install. Some packages are cached

I just
sudo apt install libppx-variants-conv-ocamlin case it was a missing requirement, and that didn't let it build either. My main goal is to be able to usexe, so maybe I'm too far in the weeds and there's a simpilar path. Any help/advice on how to get there would be amazing! Awesome work you're all doing here!
