Nestorayuso,
Just to let you know that I built the LoRa gateway following your instructions.
Instead of using a Raspberry Pi, I use an Intel i7 server based on 64-bit OpenSuse 13.2 (a bit of overkill, but this server is running 24/7 anyway) and it works fine.
I only had to add two include files to get the USB/SPI driver compiled: lora_gateway/libloragw/src/loragw_spi.ftdi.c:
#include <sys/types.h> /* BSD types */
#include <linux/limits.h> /* Linux limits */
Then everything compiles without errors.
Thanks a again for your great Wiki!
Pieter
