[Julow]

I can't explain any of the errors.

Can you try opam install ocamlfind odoc, to see if it's a problem in your Opam? If that fails with similar errors, phew! Otherwise, it might be related to the sandbox switch.

[koonwen]

Update: opam install ocamlfind odoc works fine.

Could it be that my opam installation is an amd64 version when it should ocaml-platform expects x86-64 architecture?

[Julow]

Sorry for the slow reply. There's no difference between amd64 and x86-64 but we've seen the same error on a macos arm64, where both arm and amd64 code are linked together (eg. arm64 code stored on the Opam switch and amd64 code compiled when the installer, itself amd64 code, calls opam install which somehow confuses the compiler).

Do you have an arm64 but expects to use Opam and OCaml built as amd64 executables ?

[tmattio]

Version 0.3.0 was released with support for macOS Arm64, this should solve the issue. Feel free to re-open if not
