The PKGBUILD for this package is hosted here (contributions are welcome!): https://gitlab.com/dpeukert/pkgbuilds/tree/main/ocaml-lwt

EDIT: My pacman helper chached the build of Ocaml 5.4. My bad.

Doesn't build with OCaml 5.4. I'm not sure if the cause of this issue is in ocaml-ocplib-endian. I rebuilt all ocaml-* packages, including ocaml-ocplib-endian, with 5.4

File "src/unix/lwt_io.ml", line 1:
Error: /usr/lib/ocaml/ocplib-endian/bigstring/endianBigstring.cmi
       is not a compiled interface for this version of OCaml.
It seems to be for an older version of OCaml.

@yatsuekku, @meadow: Sorry about the delay on this, I wasn't able to reproduce this, but from looking at the output, it looks like it could be caused by ocaml-ppxlib and/or ocaml-ppx_here being build with an older version of ocaml, causing the interfaces to not match with the newly build ocaml-lwt package. Try if rebuilding these helps (there might also other packages affected by this up the dependency tree, it might be easier to just uninstall all ocaml packages and start from a clean slate in that case).

@dpeukert, @yatsuekku I'm experiencing exactly the same issue.

@dpeukert For me the output of dune test command is

it gives status 1 and check() fails. These files mentioned in error does not belong to any package therefore I'm not sure why they are here. This happens on update though, I managed to install this package before.

@meadow: Hi, I wasn't able to reproduce this this, can you post the entire build log?

Hello, check() is failing on a (reasonably) clean system :)

@dpeukert Confirmed, everything is Ok. Thanks a lot.

@hurufu: Everything should be working now.

@hurufu: My bad, the lwt_domain subpackage was moved into its own package, but I didn't notice that the change hasn't been released yet, will fix ASAP.

It looks like it needs domainslib now which is unavailable in aur.
