Description Daniel Koszta 2017-08-20 11:02:22 UTC
I tried to emerge unison, but encountered the following error message:

File "/var/tmp/portage/net-misc/unison-2.48.3/work/unison-2.48.3/system.ml", line 1:
Error: The implementation /var/tmp/portage/net-misc/unison-2.48.3/work/unison-2.48.3/system.ml
       does not match the interface system.cmi:
       Values do not match:
         val symlink : ?to_dir:bool -> string -> string -> unit
       is not included in
         val symlink : string -> fspath -> unit
make: *** [Makefile.OCaml:435: system.cmx] Error 2

Note that this is very similar to bug #592020 which is from 2016 and marked "RESOLVED FIXED".

According to this https://github.com/bcpierce00/unison/issues/12  it is solved in unison-2.48.4....
so maybe a bump is needed.

Comment 5 Nico Baggus 2017-11-30 23:42:43 UTC
This may be a duplicate, but 2.48.3 still fails to build...
2.48.4 is the upstream solution to the problem, that is not stabalized...
