Particle Simulation

This project is a particle simulation using SDL2, designed to be built and run either as a native application or as a web application using Emscripten. The build script provided supports cleaning the build directory and setting the target platform.

Prerequisites

Native Build

• g++ (GNU Compiler Collection)
• SDL2 development libraries

Web Build

• Emscripten SDK
• SDL2 development libraries

Installation

SDL2 Installation

Ubuntu

sudo apt-get install libsdl2-dev

macOS

brew install sdl2

Emscripten Installation

Follow the instructions on the Emscripten website to install the SDK.

Building and Running

Build Script

The build script build.sh supports the following options:

• clean: Cleans the build directory before building.
• native: Builds the project as a native application.
• execute: Executes the project as once build is complete.
• Default (no arguments): Builds the project as a web application.

Usage

Build for Web (Default)

To build and run the project as a web application, simply run the script without any arguments:

./build.sh

To additionally start a local http server use:

./build.sh execute

This will build the project for the web and start a local HTTP server to serve the application.

Build for Native

To build the project as a native application, use the native argument:

./build.sh native

The native executable will be located in the build directory as main.elf.

To additionally execute the built file, use:

./build.sh execute native

Clean and Build

To clean the build directory before building, use the clean argument:

Clean and Build for Web

./build.sh clean

Clean and Build for Native

./build.sh clean native

Troubleshooting

Common Issues

• SDL2 Not Found: Ensure SDL2 is installed and the development libraries are available on your system.
• Emscripten Not Found: Ensure the Emscripten SDK is installed and sourced correctly.

Error Messages

• Web Build Failed: Ensure Emscripten is installed and properly configured.
• Native Build Failed: Ensure g++ and SDL2 development libraries are installed.
