I can check the memory footprint using the avr-size command.
% avr-size microcoap.cpp.elf
text data bss dec hex filename
0 18612 0 18612 48b microcoap.cpp.hex
When I enable the avr format (-C) and provide the microcontroller model, the output becomes more descriptive.
% avr-size -C --mcu=atmega328p microcoap.cpp.elf
