Free multiplatform software for linux

Distributed Multiplatform Framework is a component-based programming framework using XML (or currently a hardcoded variant) as the repository.
The samples are implemented either in console or wxWidgets. This shows the independence of the GUI or UI.
This framework includes a database form sample that let you modify content of ODBC SQL data sources.
Distributed Multiplatform Framework project shows how simple it is to create database driven applications.
With version 0.6.0 the features are nearly complete. It could show simple database forms, master-detail database forms and would also capable to show it in tabbed, dialog based or combined layouts.
Whats New in 0.7.1 Stable Release:
- The ODBC code has been fixed to work properly with MS SQL databases.
- Missing vendor libraries have been added that broke the build system.
Whats New in 1.0 RC1 Development Release:
- The most important new feature is the ability to import UML designs.
- To make a database application prototype, you now only need to design some classes with attributes and build relations using an aggregate from one class to another.

Universal Module Player or UModPlayer, is a audio module "tool-chain", providing you functions to work with modules like playing, exporting, getting information, and more.
Universal Module Player works in UNIX-like platforms, including Linux, Mac OS X, FreeBSD, Solaris...
It uses the Custom LibModPlug audio library, an improved version of the well-known LibModPlug library, supporting more than 20 formats and giving you high playing quality. It uses LibSDL to handle multiplatform sound support.
Main features:
- You can play the supported formats and seek to any order in the song. You have pause, timer, display, and other standard features.
- You can view the pattern notes while playing.
- You can specify noise reduction, megabass, surround, reverb sound options specifying the grade and the delay of most of the options.
- You can create, save and edit playlists to play a selection of modules.
- You can read and export to a file the song builtin message, the song instrument names and the song sample names.
- Each user of your UNIX box can save all the sound options.
- And much more!

STLport is a multiplatform C++ Standard Library (STL implementation). Many compilers and operational environments supported. Standard (ISO/IEC 14882) compliance. Maximum efficiency. Exception and thread safety. Debug mode.
The company was started back in 1997 by a small group of developers gathered around STLport Standard Library Project. Since then STLport has been accepted by the technical community as industry standard for multiplatform development.
Over the years, we have been able to attract top-notch professionals, who currently provide on- and off-site consulting services to hi-tech businesses in Silicon Valley and nationwide. The reputation of STLport main product and variety of skills of the STLport has allowed us to win several substantial custom software development contracts.
Enhancements:
- Add support for EVC 2005 thanks Ulrich Echkardt.
- Modification of the code use to detect stateless classes to avoid a Visual Studio 2005 warning.
- Change configuration for Visual Studio 98, do not support explicit instanciation of class template method like locale::combine or bitset::to_string.
- Fix definition of the internal _STLP_WIN32_VERSION macro giving targeted platform version, based on WINVER or _WIN32_VERSION in this order.
- Fix a use of strncpy_s that was potentially leading to a crash.

CLAM is a multiplatform software framework for research and application development for the Audio and Music domains.
It offers a conceptual model for building systems as well as tools for the synthesis, analysis, and transformation of audio signals using high level representation (notes, spectral peaks, etc.).
It also provides multiplatform system abstraction and tools for audio and MIDI file handling, device handling, GUI and XML support, and more. It has proper Linux audio architecture integration (Ladspa, Alsa, OSC, Jack, VST, etc.) and rapid graphical prototyping both for the processing core and the user interface (Qt designer integration).
Enhancements:
- More appealing audio widgets were provided for use in user applications.
- GenderChange processing is now working in real-time.
- Chord extraction and visualization has been greatly optimized.
- Multiple NetworkEditor processings can be moved at once using multiple selection, and control senders can be created by double clicking the receiver control connector.
- Initial Faust support and better Ladspa hosting were provided.

pyFlashCards is a wxPython based software for creating and studying flash cards. Thanks to python and wxPython it is multiplatform; it runs on Windows and Linux (you could probably get it to run on a Mac without too much work).
I have developed it to study at medical school because none of the flash card programs I found on the internet would do what I want the way I want it. Even though it is not complete, I think that many people can already find it useful.
Main features:
- multiplatform: Windows, Linux (and in theory Mac)
- Sebastian Leitner box system for maximizing long term memory retention
- html tags allow to highlight important concepts
- image support for visual learners
- unicode support allows studying any language

libGLI is a multi-platform library for creating 3D user interfaces, based on OpenGL.
With the help of this library, programmers can add in their own graphical application elements for the user interface and connect interface objects to their own programs with callbacks.
In other words, GLI sits between the user and an OpenGL application.
Using libgli
libGLI is built first of all to relieve the programmers who build graphic applications based on OpenGL and dont want spend half of the time for programming their own user interface. In particular, libGLI will be useful for small and average projects, where the majority of time is spent not on the user interface, but on the REAL purpose of the program. But thats not to say that libGLI is intended for small projects only. libGLI has sufficient features for building both simple and complex interfaces.
The main feature of libGLI is that it is a general interface, i.e. programmers can create interface objects of various form, color, size, etc.
libGLI is a multiplatform library written in C++. All objects are based on classes defined in the library. The programmer can inherit from these classes to build new objects.
Enhancements:
- Updated Files: INSTALL README TODO ChangeLog
- New Files: COPYING man-pages
- New GLUT Demo: EditBox
- editbox: Added Function GetText
- Demos: Moved to their own Project because of size

MUSCLE is a somewhat scalable, robust, cross-platform client-server messaging system for dynamic distributed applications that runs under any POSIX-compliant operating system.
MUSCLE has been developed, used, and refined as the networking component of BeShare, CueStation, CueConsole, and various other audio control applications at Level Control Systems for over four years.
Main features:
- Use BMessage-like muscle::Messages under any operating system.
- Send flattened muscle::Messages from one computer to another over TCP streams, eliminating unnecessary compatibility and protocol-versioning hassles.
- Run a "muscled server" on a central machine, and write (or download) client programs to log in to the server and communicate through it. Once logged in, client programs can discover who else is logged in, send muscle::Messages to other clients, and store muscle::Messages in the servers RAM for other clients to download later. Clients can also "subscribe" to selected data on the server, and be automatically notified whenever it changes. Unicast-style, multicast-style, and broadcast-style Message routing are all supported via an intelligent hierarchical pattern-matching routing mechanism. Writing multiplayer games, IRC style chat applications, SETI style distributed calculation apps, or any other type of distributed software is made easy because MUSCLE handles all the dirty work for you!
- Customize the included "muscled server" by defining your own session logic or message-streaming protocol. (Note that this is only necessary for certain specialized applications--the standard server provides sufficient functionality for most things)
- Write your client code in C++, Java, or Python. Single-threaded and multi-threaded messaging APIs are provided for all three languages.
- Or just use the included message, string, dataIO, hashtable, dequeue, string-tokenizer, reference-count, regular expression and pattern matching parser, and object-pool code by themselves, as handy cross-platform utility classes. All source code is included, and you are free to use and abuse it any way you wish.
- See the Beginners Guide for a more detailed description of the system and its capabilites.
Enhancements:
- This release includes various minor bugfixes to the Java and C++ code, as well as a few minor optimizations.
