I just got updated to XCode 12 and found that OCaml 4.07.1 - which I planned to use for a delivery of the Coq platform - doesn’t build any more. It ends with: # Fatal error: exception Invalid_argument("Sys.getcwd not implemented") Any ideas what I could do about this?

Something similar seems to be reported in opam here . Could you maybe try to compile from the tarball to see if it’s an opam problem or something that changed in the dev tools.

What does uname -s output on your machine ?

That seems ok. How did you compile opam via brew ? What does Sys.os_type report in that compiler ?

A ./configure and make world.opt in a git clone at tag 4.07.1 ends with the same error.

I get opam via Macports. Until the update to XCode 12 it did work as expected. Btw.: Compiling OCaml 4.11.1 does work with XCode 12.

Ah so it rather seems a configure problem, what’s does config.log say ? Given the other report I had the impression that configure was not run, that is that none of the tests here where succeeding (which is in fact impossible).

[image] MSoegtropIMC: How can I test this if the Compiler does not build? I meant in the compiler that built opam but forget about that. It’s unlikely to be the problem.

I wonder where the config.log file is - I can’t find anything after running ./configure. The console output of ./configure does not mention HAS_GETCWD.

uname -s just outputs Darwin.
