A game programming library

GitHub project

Gna project

Welcome to Allegro!

Allegro is a cross-platform library mainly aimed at video game and multimedia programming. It handles common, low-level tasks such as creating windows, accepting user input, loading data, drawing images, playing sounds, etc. and generally abstracting away the underlying platform. However, Allegro is not a game engine: you are free to design and structure your program as you like.

Allegro 5 has the following additional features:

News

2016-04-01 - Allegro 5.2.0 released!

After many years of development in the unstable branch, the next stable version of Allegro is ready for release! This version brings most of the features from the unstable branch, but now with a guarantee of backwards source and ABI compatibility. Allegro 5.2 is source but not binary compatible with 5.0.

Allegro 5.2 is developed a little differently than 5.0 and 5.1 were. This version combines both unstable and stable APIs in one branch. The unstable branch is no more! Unstable APIs may be changed between versions, or even removed entirely. Because of this, to use them you must opt into this instability by defining ALLEGRO_UNSTABLE definition before including Allegro's headers.

Combining the two branches will result in more rapid bug fixes and faster addition of new features.

You can download it from Gna.org. Additional packages for other platforms are available on the downloads page.

The reference manual is available online, as is the list of changes.

We would like to thank everyone who has contributed to Allegro during all these years, not only the developers, but the users who have tested pre-releases, reported bugs and submitted patches.

A book introducing game programming using Allegro 5 has recently been written by Frédéric Drouillon, titled Allegro 5 - Programmation de jeux en C ou C++.

For others, the code samples available for download on the publisher's website should be of interest as well. Check out the books section for more information.
