Port to FreeBSD

[web-sst]

I ported enough of the project to FreeBSD to build hacl-star and would like to find help to complete the remainder. Next step, how does one extend coverage for the assembly routines in hacl-star to a new OS? Is anyone interested in helping with this work?

Hi @web-vertalo

The first tidbit would be to fix hacl-star/dist/configure so that it builds out of the box on freebsd. This probably implies fixing hacl-star/hacl-star#393 so that either:

• freebsd builds without native assembly support by default, or
• freebsd uses the linux .S files if the calling convention is exactly the same.

If the ABI calling conventions differ between FreeBSD and Linux, then we need figure out how to generate a fourth variant of the assembly .S files, and you'd have to provide more context on what exactly differs.

Hope this helps! Ideally we'd love to have a complete PR including CI for FreeBSD to make sure we keep things working.

Cheers,

Jonathan

Pursuing the first suggestion from @msprotz, I cleaned up some Linuxisms (e.g. /bin/bash) and added flag setting for FreeBSD, and added -thread to hacl-star to get past the first error in quackyducky builds. Now I'm stuck here:

ocamlbuild -tag debug -use-menhir -tag thread -use-ocamlfind -quiet -pkg batteries -pkg menhirLib -pkg fstarlib -pkg process -pkg hacl-star -pkg yojson -cflags -w,-8 Main.native

Command exited with code 2.
Hint: Recursive traversal of subdirectories was not enabled for this build,
as the working directory does not look like an ocamlbuild project (no
'_tags' or 'myocamlbuild.ml' file). If you have modules in subdirectories,
you should add the option "-r" or create an empty '_tags' file.

To enable recursive traversal for some subdirectories only, you can use the
following '_tags' file:

  true: -traverse
  <dir1> or <dir2>: traverse

I don’t understand the -traverse option, but imagine that is not the issue if this code builds on other systems. The standard advice for inconsistent interface assumptions seems to be to rebuild the .mli file. I’m using ctypes.0.18.0, and there is no .ml file corresponding to ctypes_types.mli. Can someone point me in the right direction?

The quackyducky/3d Makefile does not pass the clean target down to 3d/ocaml, so the 3d/ocaml/_build directory was not removed, resulting in a dirty build.

Hi @web-vertalo perhaps it'd be helpful to break down this discussion into individual pull requests and/or issues on each project. For instance, I don't know that @tahina-pro keeps an eye on this discussion -- maybe separating the EverParse issues in https://github.com/project-everest/everparse/issues and the HACL* one on its respective bug tracker might be helpful?

We can keep this discussion for the specific issues of the everest configuration script.

Thanks!

The quackyducky/3d Makefile does not pass the clean target down to 3d/ocaml, so the 3d/ocaml/_build directory was not removed, resulting in a dirty build.

This particular issue should be (coincidentally) solved by project-everest/everparse#45 . Thank you @web-vertalo for reporting!

(That said, yes, I agree with Jonathan that EverParse-specific issues should be reported to the EverParse issue tracker.)

I thought one conversation thread and separate PRs per project was the way to go, and stand corrected. Happy to oblige.
