Hi, i’m new to Ocaml and When i try to install utop, i got this error :
#=== ERROR while installing zed.1.5 ===========================================#
Help Me please,
In the just released 4.06 version of OCaml strings became immutable by default. Not all the packages had the time to update yet. If you are new to OCaml I suggest sticking to 4.05 for the time being.
That said, after the latest package updates, I can now build utop under 4.06. (It was broken before that.) I suspect that the original poster should probably do opam update and it might then be possible to build it.
Thanks for your answer, i just do opam update, try again and utop built successful.
FYI, @dbuenzli is correct. Even though utop is now working, there are still a number of packages that don’t quite work on 4.06 yet. You may be happiest doing 4.05 for the moment.
