Fossil Math by Fossil Logic

Fossil Math is a lightweight, cross-platform mathematics library written in pure C with zero external dependencies. Designed for high-performance computation, embedded systems, and cross-platform applications, Fossil Math provides a robust set of functions for linear algebra, geometry, trigonometry, and numerical analysis, all optimized for efficiency and portability.

Key Features

• Cross-Platform Support
  Runs reliably on Windows, macOS, Linux, and embedded platforms.

• Zero External Dependencies
  Pure C implementation ensures maximum portability, auditability, and ease of integration.

• Comprehensive Math Functions
  Includes linear algebra, vectors, matrices, quaternions, trigonometry, and other numerical utilities.

• Lightweight and Efficient
  Optimized for performance with minimal resource usage, suitable for embedded and low-power devices.

• Precision and Reliability
  Provides stable and accurate numerical results for high-precision calculations.

• Modular Design
  Easily integrated into projects, with optional modules for advanced math features.

Getting Started

Prerequisites

To get started, ensure you have the following installed:

• Meson Build System: If you don’t have Meson 1.8.0 or newer installed, follow the installation instructions on the official Meson website.
• Conan Package Manager: If you prefer using Conan, ensure it is installed by following the instructions on the official Conan website.

Adding Dependency

Adding via Meson Git Wrap

To add a git-wrap, place a .wrap file in subprojects with the Git repo URL and revision, then use dependency('fossil-math') in meson.build so Meson can fetch and build it automatically.

Adding via Conan GitHub repository

packages directly from a GitHub repository if it contains a valid conanfile.py.

conan install git+https://github.com/fossillogic/fossil-math.git#v0.1.1 --name fossil_math --build=missing

Integrate the Dependency:

Add the fossil-math.wrap file in your subprojects directory and include the following content:

[wrap-git]
url = https://github.com/fossillogic/fossil-math.git
revision = v0.1.1

[provide]
dependency_names = fossil-math

Note: For the best experience, always use the latest releases. Visit the releases page for the latest versions.

Build Configuration Options

Customize your build with the following Meson options: • Enable Tests To run the built-in test suite, configure Meson with:

meson setup builddir -Dwith_test=enabled

Tests Double as Samples

The project is designed so that test cases serve two purposes:

• ✅ Unit Tests – validate the framework’s correctness.
• 📖 Usage Samples – demonstrate how to use these libraries through test cases.

This approach keeps the codebase compact and avoids redundant “hello world” style examples.
Instead, the same code that proves correctness also teaches usage.

This mirrors the Meson build system itself, which tests its own functionality by using Meson to test Meson.
In the same way, Fossil Logic validates itself by demonstrating real-world usage in its own tests via Fossil Test.

meson test -C builddir -v

Running the test suite gives you both verification and practical examples you can learn from.
