Error on building a Arduino MKR Wifi 1010 project

[horchi]

I try to build a MKR Wifi 1010 project with this settings:

BOARD_TAG     = mkrwifi1010
ARDUINO_DIR   = /home/wendel/arduino-1.8.15
MONITOR_PORT  = /dev/ttyUSB0
AVRDUDE_ARD_BAUDRATE = 57600

include /home/wendel/Arduino-Makefile/Sam.mk

did I miss something?

The result is:

I can build it using the Arduino IDE
