Warning in arduino , ignore them or how to correct them

[Vindhyachal.takniki]

1. I am using Arduino 1.8.1 & made a code in it. Board it Atemga2560 R3
   
2. I had made multiple .ino files in it & multiple headers in it. It has total 16 .ino files & 18 header files, where each .ino has its own header file plus two additional & from setup.ino rest all .ino file functions are called.

3. I know arduino is not meant for that, but i have experience in using multiple c files in other IDE. In this project I had to interface fingerprint sensor, so instead of writing new library I had used Adafruit library for that purpose, which is main reason for selection of arduino at first place, otherwise i have to write complete new library on a new microcontroller.

4. Code built was 674 bytes (8%) of dynamic memory  & 22428 bytes (8%) of program storage space.

5. Upon build below is verbose generated. It has no error, but warning in two files: One is fingerprint library & other is eeprom library of internal arduino.
Fingerprint warning does not seem to be of much error & can be ignored but i dont understand these eeprom error.
Problem is in arduino on clicking error, it wont open that file.
Should i ignore these warnings? In general i prefer code with 0 error 0 warnings.

6. Also any GOOD reference library codes for fingerprint module to be written in c for any microcontroller.
