A open-source contribution story!

Hello everybody, I'm writing today to share my Tuesday's update. I dedicate my Tuesdays to contributing to open-source projects. So I'm searching project for contribute as usual and found a interesting project called TinyFS-UNO, A crash-consistent, wear-aware, integrity-checked log-structured miniature filesystem for the Arduino Uno (ATmega328P) internal 1 KB EEPROM. Then I'm exploring it to understand, I clone it to my local machine and try to compile it. But when I'm running make run inside the TinyFS-UNO/tests directory, the build fails during the linking stage due to missing function references. ERROR gcc -Wall -Wextra -std=c99 -g -I../src -c ../src/tinyfs_eeprom_mock.c -o ../src/tinyfs_eeprom_mock.o gcc -Wall -Wextra -std=c99 -g -I../src -c ../src/tinyfs_storage.c -o ../src/tinyfs_storage.o gcc -Wall -Wextra -std=c99 -g -I../src -c ../src/tinyfs_crc.c -o ../src/tinyfs_crc.o gcc -Wall -Wextra -std=c99 -g -I../src -c ../src/tinyfs_record.c -o ../src/tinyfs_record.o gcc
