Free game library software for linux

Advanced game library project is a library designed to ease game development.
It uses the SDL library and provides 2D graphical functions, sound streaming and events functions, video streaming, AI engines, and map generator.
This software is primarily designed for LINUX.
This SDK uses the SDL library for the bitmap, sound and events system. SDL provides accelerated and portable interfaces for the video and sound hardware.
The abstraction of the low level layer makes possible the extension of adgali to other low level libraries like Allegro or GGI.
This library tends to provide useful functions for bitmap and sprite display, game GUI, game sound events and music stream , network management and video streaming.
Well, only a subset of these features are implemented for now.
Main features:
- underlying library:
- SDL
- General features:
- The library is thread safe and reentrant
- Error management system: adgali provides a system to trace the origin of an error
- Unified data streaming system: memory, files, network or archives are simple to manage and can provide the game datas
- A modular conception for the loaders (streaming system, images, fonts ...)
- A memory leak detection system
- A postmortem backtracing system
- A general parser for a general treatment of the configuration files and scripts (in the spirit of the GTK+ description files).
- All major features are designed as modules integrated with a general engine
- a dynamic loading system of modules or third part libraries (work in progress)
- A cache system is designed for all objects to accelarate object loading
- 2D graphics features are:
- 32 bits pictures management: 24 bits of colour, 8 bits of alpha
- image loading: support BMP, PCX, GIF, TGA, JPG, PNG, PPM, PNM, PGM, TIFF, XCF, XPM image formats
- unified fonts management: true type fonts (TTF using freetype 2) and bitmap fonts ( an image file and a text description file)
- Color separation, modification and combination for an image (RGB, green level, CMY and HSV)
- zone filling, copying, tiling, clipping with optionnal rotation and mirror
- color filling, mask-ing, key color alpha channel treatment
- lines drawing with clipping functions
- Graphical user interface:
- a tree organized bitmap hierarchy with an automatic refresh system to the viewport
- basic string printing

Java DIME Library project implements Direct Internet Message Encapsulation (DIME), which is a lightweight binary encapsulation format that can be used to encapsulate multiple payloads of arbitrary types and sizes into a single message.
DIME is ideal for incorporating binary attachments into any XML-based protocol. The library fully supports the latest DIME specifications.
Enhancements:
- Corrected DimeRecord.isFirst() thanks to John Russell

btnSMS Library is a C library that provides an easy interface for sending SMS messages through the Beyond The Net SMS service provider.

Messages can be sent to nearly every country in the world with many different options.

T28 library is a simple library that allows interaction with a Ericsson T28 phone (and probably works with other models as well). T28 library does not have SMS support.
Main features:
- load/save phonebook
- set language
- set audio mode selection
- get battery properties (level, temperature, etc)works only on T28
- get signal level
- send keys to mobile device
- set date/time
Enhancements:
- Lots of documentation was added.
- The code was cleaned up and tested with other SE models.
- Minor bugs were fixed.

GPM client library (libgpm) package is an stand-alone version of GPMs client library, used by many console applications for mouse access.
Despite the (now quite aged) GPM package it contains just the client part (no server), and provides a pkgconfig descriptor (libgpm.pc) for easy importing.
Enhancements:
- This release pulls in some outstanding patches from upstream and Gentoo. It adds a Gentoo ebuild file.

conexus is a generalized C++ I/O library that includes support for BSD sockets, serial/TTY, and packet capture (via pcap).

conexus library utilizes sigc++ for object communication. A companion library, conexusgtk, provides a set of gtkmm widgets.

Papyrus is a 2d C++ scenegraph library that utilizes the cairo library to perform drawing operations. In this respect, Papyrus Library is similar to the Gnome::Canvas library.

The initial implementation focuses on function over form, and as a result it should not be considered an optimized run-time library (but it does run reasonably well).
