Great! Thanks for the quick response, @hv15

Thanks @RubenKelevra for reporting, upstream already fixed this in https://github.com/ocaml-community/cppo/pull/106, so I apply the patch to the current release. Cheers, Hans

@patlefort thanks, I was still on dune 3.1.0, the --libdir flag behavior changed in 3.2.0 for some reason. Pushed PKGBUILD fix for this.

Small problem:

dune install: option --libdir: the path must be absolute to avoid ambiguity

From dune's manual:

       --libdir=PATH
           Directory where library files are copied, relative to prefix or absolute. If --prefix is specified the
           default is $prefix/lib. Only absolute path accepted.

It's rather confusing, it says it can be relative to $prefix and then says it must be absolute.

I can confirm this issue. Downgrading dune to 2.9.3 fixes it for me. I voted on the bug you opened in the issue tracker in the hopes that it will get fixed soon ^^

@jaywalker, I've now been able to recreate the error message... its really weird as I can find ocamlbuild with ocamlfind, but not with dune. This is either something with how the ArchLinux ocamlbuild package is built/installed, or something with dune. I've create an upstream issue for this https://github.com/ocaml-community/cppo/issues/82.

To make things even weirder, if I have a opam environment setup with ocamlbuild installed locally, I can build cppo just fine. I am not sure if this latter detail is helpful or not.

EDIT: seems to be with dune, created https://bugs.archlinux.org/task/74061

Thanks for the update @hv15. This was on a fresh system, so I'm pretty up-to-date. I got to installing this package by trying to install the google-drive fuse package. When it failed on cppo, I tried building the PKGBUILD manually, and then tried reproducing its steps manually; All resulted in the same error

hi @jaywalker, on my system I'm not able to replicate your issue but I'm also not using the latest releases --- I haven't done a full upgrade since january. Once I've done this (maybe later today), I'll look more closely at this.

I'm having a problem building this and I'm not sure what to try now...
