Hi, I’m trying to send an UDP packet using Async: (* corebuild -pkg async sendudp.native *) open Core.Std open Async.Std let buf = "hello world\n" |> Iobuf.of_string |> Iobuf.read_only let addr = Unix.Inet_addr.of_string "127.0.0.1" let socket_addr = Unix.Socket.Address.Inet.create addr ~po…

As far as I know, Core_async doesn’t support anything beyond linux. You’d better stick with Lwt if you are doing crossplatform programming.

This is not true. Async is generally portable across multiple architectures, and internally, we use Async seriously within a JavaScript environment. It’s true that we don’t routinely test on OSX, though I use it there myself fairly regularly for personal projects. I think UDP on OS X is less used (…

Async maintainer here. Like Ron said, Core and Async are built to support a variety of platforms. They are by no means built or intended to be Linux-only. However, the majority of the development and testing of Core and Async do occur on Linux, so there are a few places where we don’t have as good s…

Ok, thanks. I was suspecting this was a bug but wasn’t 100% sure, since it could’ve been that I messed up my build environment and it was somehow affecting the code. It looks like macOS equivalent of MSG_NOSIGNAL is SO_NOSIGPIPE, I’ll try to contribute a fix when I get to it. [image] seliopou: …

[image] Leonidas: I should mention that it would be nice if there was a tool which would set up a Jane Street development environment because I had to pin quite a number of packages when they were failing to build. Try adding GitHub - janestreet/opam-repository: Opam repository for the develo…
