Ubuntu 18.10 / 19.04: @opam/ocamlfind@opam:1.8.1 build failed

[Jeric de Leon]

Tried to follow the Building and Installing steps using a plain vagrant box with generic/ubuntu1810, encountered different issues. Tried it again on a generic/ubuntu1904 box, same issues.

• Steps to reproduce:

  1. Using a generic/ubuntu1810 or generic/ubuntu1810 vagrant box (or any Ubuntu 18.10 / 19.04 machine), follow the building and installing instructions
     • I had to give it at least 2GB of ram to build esy-harfbuzz
     • I should note that I tried building hello-reason from Esy's Getting Started Guide, and the same machine was able to build this hello-reason project despite it requiring the same version of ocamlfind (@opam/ocamlfind@opam:1.8.1@ff07b0f9)

Its possible we need to update the build dependencies again. I did a round of updates to the Fedora ones a few weeks ago, as someone was hitting issues there, but it may be that the Ubuntu ones are now also out of date (and we are being saved by the pre-installed deps in the CI).

Can you post the content of ocargs.log mentioned?

[Glenn Slotte]

I just came across this as well. Most likely it's caused by this bug: esy/esy#1171

There's a couple ways to work around this:

1. Pin the OCaml dependency to 4.10.0
2. Install and use @esy-nightly/esy instead. Unfortunately that will trigger another bug in esy-harfbuzz, being addressed here: revery-ui/esy-harfbuzz#6

@marcinkoziej Reran on a new VM, this is the only ocargs.log file I could find on the system afterwards:

.esy/3/b/opam__s__ocamlfind-opam__c__1.8.1-c62bd863/ocargs.log

ocamlc -o extract_args str.cma extract_args.ml
tools/extract_args/extract_args: 2: tools/extract_args/extract_args: Syntax error: word unexpected (expecting ")")

Closing due to age.
