Support FreeBSD amd64

[mdyring]

Hi team,

Trying to build namada from source inside a FreeBSD jail. On FreeBSD 13.2 amd64.

Inside a clean jail, doing a pkg install gmake rust llvm protobuf before the build will get me pretty far. However I am stuck here:

It would be great if you could provide release binaries alongside the Linux and Darwin builds. Hopefully not far from Darwin to FreeBSD and it would be great to get native FreeBSD performance instead of having to run it in a Linux VM.

Hi @mdyring, thanks for opening up an issue! I think right now this isn't at the top of the list of our priorities, but it would be a nice thing to have in the foreseeable future.

Regardless, I can already identify the culprits that make your build fail:

• sysinfo version 0.21.1 -- an upgrade to the latest version adds FreeBSD compat it seems
• file-lock -- we're replacing this with a crate that may fix FreeBSD builds in apps: use fd-lock instead of file-lock for cross-platform support #1605

[mdyring]

Sounds like there is a good path forward, building locally is not a major issue for me. Happy to give it a spin once ready.

[tzemanovic]

I've opened #1695 as it looks like a low hanging fruit - we'll try to include both of these in the next release

[mdyring]

I'm keeping my fingers crossed that this will be ready for next testnet, that way I can claim "first Namada on FreeBSD" :-)

[tzemanovic]

the PRs were released in 0.20 so hopefully that unblocked building on FreeBSD. If something doesn't work, please comment and/or reopen this issue

Almost there, stuck on wasmer-vm.

error: Unsupported platform

It is supported from v3.3.0 onwards:
https://github.com/wasmerio/wasmer/blob/master/CHANGELOG.md#330---03052023

[tzemanovic]

depends on #821

@mdyring hey, in case you are still interested, could you please confirm that version v0.38.0 (the latest release) of Namada works with FreeBSD? cheers
