> Currently, Tez cannot be built out of the box because tez-api needs a
> protobuf compiler (protoc executable), which was also a problematic
> dependency in a sense that downloading/installing it is a burden on
> developers. Even if we have tons of
> [gists|https://gist.github.com/abstractdog/1eddeac9cc09815ded5253e3a83293a8]
> for that, it's still uncomfortable. Not to mention if we want to support more
> versions at the same time.
> Shipping the typically used versions (2.5.0, 3.x for later) of the protoc
> executable could make sense, but I'm not sure at the moment if it has any
> license issues, [need to
> check|https://github.com/protocolbuffers/protobuf/blob/master/LICENSE], also
> it's not general, instead an intelligent script could do it for developers.
> For 2.5, it should be done from source:
> https://github.com/protocolbuffers/protobuf/releases/tag/v2.5.0
> But for newer versions, the protoc executable can be downloaded from the
> releases page: https://github.com/protocolbuffers/protobuf/releases/tag/v3.7.1
> https://github.com/protocolbuffers/protobuf/releases/download/v3.7.1/protoc-3.7.1-osx-x86_64.zip
> https://github.com/protocolbuffers/protobuf/releases/download/v3.7.1/protoc-3.7.1-linux-x86_64.zip
