Making & Working with Libraries in C++ – Cherno-Style (Headers, Linking, Static vs Dynamic) 🪓🔥

Branch: making-libraries
From The Cherno's C++ series — the episodes where he screams about "linker hell", missing symbols, DLL nightmares, and why build systems are both evil and necessary.

What "Making a Library" Actually Means

A library is just your code that you want to reuse in multiple projects (or share with others) without copy-pasting everything.

Two main types:

Cherno:

"Static is simple and safe — everything in one exe.
Dynamic is powerful but brings DLL hell. Choose wisely or suffer."

Step-by-Step – How Cherno Teaches Making & Using Libraries

1. Making a Static Library (Engine as .lib)

Create your "Engine" project → build as static lib (.lib)

// Engine.h (header)
#pragma once

void Log(const std::string& msg);
int Add(int a, int b);


// Engine.cpp (implementation)
#include "Engine.h"
#include <iostream>

void Log(const std::string& msg) {
    std::cout << "[ENGINE] " << msg << "\n";
}

int Add(int a, int b) { return a + b; }
