Faur is my personal C framework for my hobby video games.

Features include software or accelerated 2D graphics, abstractions for inputs and sound, application state management, entity-component-system model, and utilities to help with data, files, math, memory, strings, time, and more.

Faur builds native on Linux and cross-compiles for Web, Windows, and some embedded devices like the GP2X and Gamebuino handhelds. The build system uses GNU Make 4.1 and Python 3.6 or later.

Cross-Compile for Other Platforms

I started Faur by collecting my GP2X games' shared code into a static library. Over time I added support for more platforms:

Target	Host	Toolchain	Dependencies	More Info

The default toolchain paths are in make/global/sdk.mk, and they can be overridden in a project Makefile or globally in ~/.config/faur/sdk.mk. To build for different targets, change include $(FAUR_PATH)/make/default.mk to use other files from $(FAUR_PATH)/make.
