Build a Real-Time-Multiplayer-Game-Chat-Server in C++ that allows multiple clients to connect, exchange messages, and demonstrate real-time communication.
The goal is to establish a clean project structure, configure builds with CMake, and implement a server that can handle multiple clients concurrently.
Initially, the server only echoed messages back to the sender. We upgraded it to broadcast messages to all connected clients — the foundation of a multiplayer chat or game system.
From the project root:
- Remove any old build folder : rm -rf build
- Create a new build directory : mkdir build && cd build
- Run CMake to configure : cmake ..
- Compile the project : make
This produces two executables in build/: server and client
- Start the server : ./server
- Run multiple clients : ./client
- TCP server listening on port 5000
- Thread pool for handling multiple clients concurrently
- Broadcast messaging so all clients see each other’s messages
- Clean CMake build system for easy compilation
