Resolved by installing libev-dev apt package and conf-libev opam package.

Note:
I used to be able to install lwt directly from opam, but opam upgrade failed due to aforementioned error.

We better reopen this, because it means that the OS was detected as Windows. I understand that you did opam install lwt without conf-libev. Can you tell me anything else about steps to reproduce this? Was this in a container by any chance? Anything else about the environment, or the sequence of commands from installing opam until this error?

I tried to recover the list of actions done by opam but I don't think I can find it.
I did opam update && opam upgrade on my Ubuntu 18.04 machine, not in a container, and lwt reported an installation failure.

It seems all the Ubuntu installations I have ready access to are 16.04, so I will set up a VM or container later and try. Thanks for the report.

I tried with a docker image of 18.04 to install latest lwt, it installed without problems.
I guess there was a specific problem with my machine that caused the build failure.

Ok, I will close this for now, then. Lwt builds routinely without conf-libev on 16.04 (e.g., in Travis, and locally on my machine). I'd assume it also builds on 18.04 in most circumstances :) Please do post if you see this problem again.

LWT 5 support (#804)
5442463 
* Lwt 5.* wont compile

Resolved by installing conf-libev as suggested by ocsigen/lwt#760

* Nested calls to `Lwt_main.run`

Lwt 5.* prohibits nested calls of `Lwt_main.run`. Previously every call to `Proc.run` would invoke `Lwt_main.run` which could result in nested calls. To resolve this `Proc.run` no longer calls `Lwt_main.run` rather we now have a function `start : (unit -> 'a Lwt.t) -> 'a` which is called once when the evaluator starts. This requires a change of types for `Proc.run` such that it returns a `Lwt` computation, meaning its signature is now `(unit -> 'a Lwt.t) -> 'a Lwt.t`. As a consequence it is necessary to move `value` from `evalir.ml` into the Lwt monad, because `Proc.atomically` (used in `ApplyPure`) was re-calling the main LWT entry point.
