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: Supported on Windows, Linux, Mac OSX, iPhone and Android User-friendly, intuitive C API usable from C++ and many other languages Hardware accelerated bitmap and graphical primitive drawing support (via OpenGL or Direct3D) Audio recording support Font loading and drawing Video playback Abstractions over shaders and low-level polygon drawing And more! News 2026-02-09 - Allegro 5.2.11.3 released! This is a new stable release, fixing an ABI regression in introduced in 5.2.11.0. A summary of the changes can be found here.

Additional packages for other platforms are available on the downloads page. 2025-04-20 - Allegro 4 moved to its own repository. We’ve moved Allegro 4 sources to its own repository. Previously (and, in fact, currently) Allegro 4 was placed in a few separate branches in the main Allegro 5 repository. This made it hard to find and cumbersome to use. So, we’ve moved the relevant branches, tags and issues to a separate repository. We’ll probably make a new release so that there is also a “latest” release with the relevant source archives (and also to nominally treat a bit of bitrot). Note that Allegro 4 should still be treated as mostly abandoned, and won’t be receving regular updates. This change is for the convenience of the few remaining users of it, and to enable easier historical exploration of the repository using Github’s tooling. 2024-12-28 - Allegro 5.2.10.1 released! This is a new stable release, containing some fixes to regressions added in 5.2.10. The changes only affect MacOS, as well as the source packages (which were malformed in 5.2.10.0). A summary of the changes can be found here. Thanks to everyone who tested and contributed! You can download the sources and MinGW binaries from GitHub. Additional packages for other platforms are available on the downloads page. 2024-11-27 - Allegro 5.2.10.0 released! This is a new stable release, containing bug fixes, new features and many assorted improvements.

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 GitHub. Additional packages for other platforms are available on the downloads page. The reference manual is available online, as is the list of changes.

Enterprise IT (Information Technology) is a $3.8 trillion per year industry worldwide. Most of it is waste. We’ve grown used to projects costing tens of millions or even billions of dollars, and routinely running over budget and schedule many times over. These overages in both time and money are almost all wasted resources. However, the waste is hard to see, after being so marbled through all the products, processes, and guiding principles. That is what this book is about. We must see, understand, and agree about the problem before we can take coordinated action to address it.The trajectory of this book is as follows: This book is the first part of a trilogy to follow Software Wasteland. In Software Wasteland, we detailed the current poor state of application software development. We offered some tactical advice for reducing some of the worse of the excess. This is the first book in the “what to do instead” trilogy. “Even if the thought of data modeling makes you cringe, Dave McComb’s latest book makes the case that it is a necessary exercise for the data-driven organization. The ‘Data-Centric Revolution’ shows how to be data-driven in an extensible, flexible way that is baked-into organizational culture, rather than taking a typical project-by-project approach. The book is a fun, insightful and meaty read, well-illustrated, and with endless wonderful examples.”Doug Laney, Principal, Data & Analytics Strategy, Caserta, and author of the best-seller, “Infonomics: How to Monetize, Manage, and Measure Information for Competitive Advantage” “Dave McComb has laid out a roadmap to travel the exciting path towards data centricity. Dave’s passion for semantic modeling is contagious and his expert advice will give you the motivation to rethink application development and the direction needed to deliver value in your organization with linked data.”Nic Seyot, Executive Director, Information Management at a major investment bank “In his new book, Dave teaches us why most of the stack we’ve spent decades trying to maintain is just a big, unmanageable pile of duplicative, inflexible code. He shows us how to collapse the stack and blend the logic and data each business needs to thrive, in one contextually rich, machine readable, dynamic, smart data layer. The bloated app and process layers of the stack go away, leaving a thin execution layer calling on the power of the smart data underneath. After ‘Software Wasteland’ explained the problem, ‘The Data-Centric Revolution’ articulates the solution.”Alan Morrison, Sr. Research Fellow, New Services and Emerging Tech, PwC From the age of punched cards to today’s internet-driven systems, one thing has stayed fairly constant: software vendors and their implementers have been driving the Enterprise IT industry. This is changing. It will be hard to see initially, but it’s already happening in some more prescient organizations. As organizations realize they can take control of their own destiny by adopting data-centric principles, they will see their dependency on application software wither. The cost of running internal information systems will drop at least ten-fold, and the cost of integrating them will drop even more rapidly. This will decimate the $400 billion/ year application software industry and the $400 billion/year systems integration industry. The benefit will accrue to the buyers, and will accrue earliest to the first movers.The trajectory of this book is as follows: Dave McComb is the President and co-founder of Semantic Arts, a consulting firm that helps organizations uncover the meaning in the data from their information systems. For 18 years, Semantic Arts has helped firms of all sizes in this endeavor, including Procter & Gamble, Goldman Sachs, Schneider-Electric, Lexis Nexis, Dun & Bradstreet and Morgan Stanley. Prior to Semantic Arts, Dave co-founded Velocity Healthcare, where he developed and patented the first fully model driven architecture. Prior to that, he was part of the problem.
