You can still use the build script (dev/build.sh) included in the [resin.io](http://resin.io) stuff to build the executable. ---

This one use the latest @kersing packed forwarder and based on @jpmeijers build script , you can pick up script and get what you need > **[ch2i/LoraGW-Setup](https://github.com/ch2i/LoraGW-Setup)** > > SX1301 Lora Concentrator Raspberry PI based gateway setup - ch2i/LoraGW-Setup ---

@Charles Just had a quick glance , seems to be “easy” to build. Will try during next week Thnx /Bingo
