Sir,

I am using STM32L071 with lmic (LoRaWAN)...i can compile 100%

But, how can i use use Serial.print into the lmic routines to debug values ?

I am getting the following error

Well you can't as the Serial in a C++ instance object so you could not call it from C file.
You can try to use the core debug feature by defining CORE_DEBUG then include core_debug.h and use:
void core_debug(const char *format, ...)
