Hey, where did this move? I also see protobuf as a requirement and not sure how to do that.

[paolostivanin]

Sorry, I don't follow. What are you trying to achieve?

I was trying to build the client of OSX.

Just tried now.
Got:

Not sure how to get cotp for mac without building it. Can try that later

You need to build and install libcotp: https://github.com/paolostivanin/libcotp
