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.

Install on Debian-based Linux

$ sudo apt install build-essential git python3 python3-pil
$ sudo apt install libsdl2-dev libsdl2-mixer-dev libpng-dev
$ git clone https://github.com/alxm/faur.git

Create New Project

$ faur/bin/faur-new --name hello
$ cd hello/build/make
$ make run FAUR_PATH=../../../faur

Move the square with the arrow keys or with a game controller.

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:

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.
