@ktrls: Hi, as the error says, the issue is caused by some of the dependencies being built with an older version of OCaml. Rebuilding ocaml-compiler-libs-repackaged (and any other dependencies mentioned in the build log with the same error) should enable ppxlib to build, or if you don't want to hunt down the affected dependencies, uninstalling all OCaml packages and starting from a clean slate would also work.

Hi, when I try to install ocaml-ppxlib the process stop with a lot of errors.

This is the tail of the error stack

It seems to be for an older version of OCaml.

but the OCalm version is the latest one.

Can you help me to resolve?

Build was successful, but then the packaging phase failed for me. What could be the issue? (Similar problem just happened with another Ocaml-based AUR package.)

==> Starting package()...

error: failed to build 'ocaml-ppxlib-0.26.0-1'

Edit - Disregard. My PATH var got prepended by opam causing this issue. Removing its entry resolved it.

Failing to build. Tried reinstalling stdlib-shims and sexplib0. No improvement.

thx :-)

@simona Fixed, sorry about the delay.

@simona Sorry about that, I forgot to update the patch. Will try to fix it this evening.

@TheGoliath No worries, glad it's working now.
