Hi, welcome to the forum! There was this thread where people got building stuff. I don’t know if the repo’s on GitHub can be build that way right now.
The routing library is undergoing an important rewriting. The external API and the internal outlines have been laid out. The library is currently not in a functional state. To obtain the last functional state of Routing we refer to Routing version 0.2.8, as published on crates.io. We expect it to be a few more days of work before routing will be published as version 0.3.1, the first expected functional version of the new routing API. The published version 0.3.0 should only be used by a user library to compile against, and prepare for the upcoming new interface.
