I wanted to make a Hello World discord bot, and I found dscord[1] on dub. It even has an example bot Jeff[2], but it won't build. The machine is running Manjaro/Arch linux x64.

Is that vibe.d not linking with openssl? There are more errors but it would be a bit long to paste them all.

Apologies, this was meant to go into Learn. I'll post it there instead.

vibe.d is using the deimos openssl bindings, and those are outdated. See [1]

While vibe.d can use botan instead of openssl, due to an open bug with dub, it won't work. I do have a PR [2] fixing it, but it ain't pretty. Also, consider [3] as workaround.
