C Linker error

Fun little linker error I can't seem to fix.  any suggestions?


/tmp/ccyc6Jxc.o: In function `main':lab1.c:(.text+0xd8): undefined reference to `get_next_line'
:lab1.c:(.text+0x130): undefined reference to `get_next_line'
collect2: ld returned 1 exit status

that's why you should learn to name your functions. fag
