Linker command failed with exit code 1 - ld: Undefined symbols [duplicate]

Question

when trying to make the executable file in C, this error appears. I don't know what I did wrong, what can I do to fix this?

Error code

main.c

bib.h

print.c

I ran this two commands, but same error:

clang main.c -o main   OR   clang ./main.c -o main

gcc -Wall -o main ./main.c

You forgot to include the print.c file in your clang command. You must do this otherwise the compiler has no idea where the code to the void print(); function actually lives. You're essentially telling it that it exists but not telling it what it does so it throws.

clang main.c print.c -o main
