I am also having this problem

This is on Linux (Arch) as well. I am not familiar with go, updated build instructions are needed.

I got a little further by banging rocks (and doing this: go mod init sga ; go mod tidy ; go mod vendor ; go build)

# sga
./agent.go:54:108: undefined: ssh.Filter
./agent.go:66:33: undefined: knownhosts.OrderHostKeyAlgs
./agent.go:70:20: undefined: ssh.NewProxyConn

./delegated_client.go:608:4: unknown field KexCallback in struct literal of type ssh.Config
./delegated_client.go:611:3: unknown field DeferHostKeyVerification in struct literal of type ssh.ClientConfig
./delegated_client.go:629:44: undefined: ssh.NoMoreSessionRequestName
./delegated_client.go:631:50: undefined: ssh.NoMoreSessionRequestName
./delegated_client.go:634:51: undefined: ssh.NoMoreSessionRequestName
./delegated_client.go:652:14: c.sshClient.RequestKeyChange undefined (type *ssh.Client has no field or method RequestKeyChange)
./delegated_client.go:652:14: too many errors

So, a standard library was forked for some reason. I'm not really sure why, and there's no tests. It would be challenging to update this to modern go that supports arm. I'm more interested in the underlying library to talk to mosh. It would be interesting to break that out into its own library for importing. As a gui though, it would be better suited to a gui friendly language.

Doesn't work using homebrew either for intel Macs. Looking closer it looks like the team just hasn't kept up with the OS releases in general. Is this a dead project? Looking at check ins, it looks like no movement for 3+ years.

Sadly, yes, this does appear to be a dead project. The Stanford students working on it have graduated, and the professor leading the project seems to have moved on to other projects as well. Quite a shame, as a mosh developer in mobile-shell/mosh#120 emphatically pointed people here as the One True Solution.

The professor and the Mosh developer are the same person. :-) I think if somebody is willing to take this over, we're interested to hand this over and work with you. I spoke with the original developers (and somebody interested in taking this over) back on Oct. 5 and we were going to work on a transition plan, but I fear intervening events in the Middle East may have taken priority for them. :-(

I don't use mac, but I use the Nix sga-guardian package for different architectures on Linux and there's one for aarch64-darwin.

If you don't use nix as a package manager, you could try extracting the binaries.

#33 (comment) works for me™

Sadly it doesn't work with Go 1.22 since they removed GO111MODULE=off support for go get but everything I tried below it works.
