How to fix error : undefined reference when linking (assembler)?

Question

Programming

When linking, the linker throws an error:
(.text+0x1e): undefined reference to `error_exit'
Source code HERE .
In theory, the program should work like a regular pwd command on UNIX systems.

Help me please!

Answer 1

error_exit, as far as I understand, is some system call or function from the standard C library. Accordingly, when linking, you need to additionally specify the library in which the error_exit function is implemented.
