Cannot install core_kernel due to path issues #43

Open msaffer opened 8 years ago

msaffer commented 8 years ago

I followed the install instructions, when I try to install core_kernel, I run into issues [3]. My best guess is that opam is doing the wrong thing because it thinks it's on a windows system[1], even though I'm running inside of cygwin, and because of that it's exporting PATH with semicolon separators instead of colons [2]. I think this causes ppx-jane to not be in the path when opam tries to compile it.

I tried doing opam config set os cygwin which just broke things. Trying to upgrade to 113.33 didn't help either.

This is on a 64-bit system [4]

I think this is one more instance of @dra27's opam fork not calling bash with proper quoting. It's very primitive right now... and the install: directives are sometimes not run properly.

protz commented 8 years ago

Oh but you shouldn't use opam's config -env feature. Have you followed the instructions at http://protz.github.io/ocaml-installer/ for setting a proper PATH?

msaffer commented 8 years ago

Yep, I put the following in my ~/.bashrc at first: export CAML_LD_LIBRARY_PATH=$HOME/.opam/system/lib/stublibs:/cygdrive/c/OCaml/lib/stublibs export MANPATH=$HOME/.opam/system/man:$MANPATH export PATH=$HOME/.opam/system/bin:$PATH

Do you know any way around this? Maybe I should fork that repo and try and fix it? I got the feeling from @dra27's patches that someone was able to get core working on windows with that opam repo.

The repository at https://github.com/fdopen/opam-repository-mingw is supposed to go along with the custom-made OPAM binary from @fdopen that's listed on the wiki page; however:

It's probably not very hard to fix shell invocations -- I remember dealing with that a while ago as I hunted down some bug in ocamlbuild. I do have, however, more urgent things to deal with :(.
