Hello World With Libc: A Deep Dive into Libraries and Dynamic Linking
Introduction In our previous article, we built a “Hello World” program without using the C standard library. We made direct system calls, provided our own _start entry point, and understood how programs interact with the operating system at the lowest level. But that’s not how most C programs are written.
