While it should be possible to get this working if dependencies are satisfied (it’s often better to cross compile) keep in mind that an option is to run the gateway bridge on a different machine (such as the one running the rest of the LoRaServer stack) and use the legacy UDP protocol between the gateway and that. It’s also possible to create your own solution for the translation; ended up doing that in an afternoon to fulfill some unique needs.
