QUESTION
I've been working on an assignment where we are given a .ssv file that contains bank accounts in the first column and transactions in the second (20 is adding $20 and -20 is taking away $20), and are asked to create a linked list of the accounts using multiple c file.
There are three in question: main.c (opens the ssv and goes line by line), ssv.c (contains a function for parsing out the data from the fgets() string) and linked.c (creates the linked list and updates the account balances by matching the account number and adding the transaction). They are required to remain separate and cannot be made into .h files.
As my code stands currently, nothing it getting put into my linked list header as it would get overwritten every iteration of the while(fgets()) if i just had it write straight to the header. Therefore, I'm looking for some way to have the first line get written to the header and then the loop continues like normal, adding new accounts or updating transactions in current ones. I also noticed that it doesn't seem to be updating the transaction amounts, as it just lists account 10 as having no money. Any input anywhere would be appreciated.

QUESTION
I've been working on an assignment where we are given a .ssv file that contains bank accounts in the first column and transactions in the second (20 is adding $20 and -20 is taking away $20), and are asked to create a linked list of the accounts using multiple c file.

They are required to remain separate and cannot be made into .h files.
I've assembled a makefile to put all of them into one executable, but when I run the make, it returns and error. I did some debugging and found that it seems to compile objects files of ssv.c and main.c, but not linked.c, leading to some problems where I use linked.c functions in main.c. I've included each of the file's codes below, as well as the error message that appears when I try to "make". Any help finding the issue would be greatly appreciated.
