@ivankravets the LDF seems to have a problem here. Latest PIO core. Minimal example [env:nanoatmega328] platform = atmelavr board = nanoatmega328 framework = arduino lib_deps = adafruit/Adafruit GPS Library@^1.5.3 arduino-libraries/SD @ 1.2.4 SoftwareSerial lib_ldf_mode = deep+ #include <Arduino.h> #include <Adafruit_GPS.h> #include <SoftwareSerial.h> // you can change the pin numbers to match your wiring: SoftwareSerial mySerial(8, 7); Adafruit_GPS GPS(&mySerial); void setup() {} voi…

Commenting out the lines as described does compile…

SOLVED.
