Windows support #1

Open ulrikstrid opened 5 years ago

ulrikstrid commented 5 years ago

This is a issue to track Windows support. It is larger than just this repo as when this works on Windows we have working webserver built with Reason/OCaml on Windows.

Current build tree, I'll try to keep it updated

Opened PR to ocaml-nocrypto dune branch to look for CFLAGS that we need to provide endian.h for Windows.

https://github.com/mirleft/ocaml-nocrypto/pull/160

ulrikstrid commented 5 years ago

Packaged a endian.h "polyfill" with esy https://github.com/ulrikstrid/esy-endian

The current blocker is x509:

I also have some overrides that I need to upstream but that shouldn't be a huge deal as they are just taken from https://github.com/fdopen/opam-repository-mingw in most cases

ulrikstrid commented 5 years ago

With this PR we get past x509 and I'm now hitting some issues in the tls library.

The x509 PR isn't good, I need to find a way for it to use the new Cstruct project structure instead. Might be able to rebase the dune branch on master instead

ulrikstrid commented 5 years ago

Using the latest x509 fixes the issue, forgot I set the version previously. Current error on ocaml-tls:
