Multiple failures on macOS sierra

[drautb]

I'm having problems very similar to this question. I've also posted this on SO here.

I have a MacBook Pro on macOS Sierra. I've installed ocaml and opam via brew. (brew install ocaml, brew install opam) This installed ocaml 4.03.0, and it appears to work fine on its own.

I tried to install oasis (opam install oasis), but the installation failed due to a failure in installing ocamlfind:

➜  ~ opam install ocamlfind

I thought it might be related to ocaml 4.03.0, so I tried switching to ocaml 4.02.1. (opam switch 4.02.1) This fails also:

I've tried reinstalling XCode, I've tried reinstalling ocaml and opam via homebrew with the --build-from-source option, (including rm -rf ~/.opam) and the errors persist.

Has anyone else had issues like this?

I'm having similar problems with macOS Sierra 10.12.3, Xcode 8.2.1:

I had the same problem trying to install mirage, the problem is because the current directory is not in the CDPATH by default on macOS X. The posix /bin/sh will not "cd src" though can "cd ./src". The quick fix is to do the following before running opam (or just put it in your .bash_profile.

export CDPATH=.
opam install WHATEVER

@richardblackman ah, thank you!

Is this something that should maybe be added to the ocaml install script? I had some issues on rescript-lang/rescript-compiler#1645 where it turned out it was the same problem
