@pha-qu Hey, I tried reproducing the test failure, but I wasn't able to so far. I'll try looking into it some more, but for now, you can change the PKGBUILD to skip that test, which should let you build this package:

Hi, Build bunked by a dependency test failure: Testing library 'unix'... .................................SSSSSS............................................................................................................................................................F................... Test 'mcast-join-loop' in suite 'unix_mcast' produced 'false' ==> ERROR: A failure occurred in check(). Aborting...

When building ocaml-utop the process halts with an error that appears to be caused by post-build testing in this package i.e. this package isn't functioning/building correctly. I'm using an up to date Ocaml toplevel from the community repos: The OCaml toplevel, version 4.09.1

All other dependencies are sourced by the ocaml-utop package build script, I've posted there too, just in case the fault is there's. Thnx

@dpeukert thanks, that helped :) I love this OS and the kind people maintaining it and helping out!

@ogghi This is likely caused by an update of ocaml causing the code compiled with the previus version to no longer be compatible with the newly compiled code. I've bumped the pkgrel of all my affected packages, but you'll have to rebuild any other ocaml packages (ocaml-react in this case) manually.

Ain't working here:

File "none", line 1: Error: Files /usr/lib/ocaml/react/react.cmxa and /usr/lib/ocaml/stdlib.cmxa make inconsistent assumptions over implementation Stdlib__weak

It is fixed now. I guess I was too hasty with the update. Thanks!

Build fails with this error:

File ".ppx/788f1000e783f5c1c765995f909d851d/_ppx.ml", line 1:
Error: Files /usr/lib/ocaml/ppx_tools_versioned/metaquot_410/ppx_tools_versioned_metaquot_410.cmxa
       and /usr/lib/ocaml/ocaml-migrate-parsetree/migrate_parsetree.cmxa
       make inconsistent assumptions over interface Migrate_parsetree__Migrate_parsetree_driver

Please note that it’s currently (as of 2018-02-05) impossible to update this package as the new version depends on ocaml-migrate-parsetree which can’t be built due to bug FS#57200.
