OK, I'm making some progress a Bitbake recipe for the Tailscale client built using Go from various samples I found in the OpenEmbedded layers.
However, I'm running into import issues during compilation and I'm hoping a person familiar with Go might be able to provide some hints. From what I can tell, Go packages to are allowed to declare that they must be imported using a specific name <https://golang.org/cmd/go/#hdr-Import_path_checking> and it seems that declaration is included in the Tailscale source code.
Is there a way to craft the Bitbake recipe to honor that requirement for the Tailscale Go source code?
Currently, my Bitbake recipe for Tailscale looks as shown below.
tailscale_1.0.5.bb
