The Ecere SDK is a cross-platform toolkit for building software applications. It currently runs on Windows, Linux, Mac OS X (through X11), FreeBSD, and the Android OS. It should run on other Unix platforms with minor testing/tweaking. With the Ecere SDK, you can develop applications once and deploy them on all supported platforms alongside a lightweight runtime environment. It introduces eC, an object oriented language derived from and fully compatible with C, compromising neither runtime performance nor ease of use. A built-in 3D engine supporting both Direct3D and OpenGL is fully integrated.
The Crow Designer is a visual editor for building graphical user interfaces. Interfaces are saved in files of the GuiXml format and may be involved in applications by means of the GuiLoader library. During editing, the following instruments are available to a user: a palette of GUI controls, an object tree, an editor canvas, and a hierarchical property explorer. The property explorer allows you to work with nested objects and arrays as well as with several selected objects simultaneously. The designer uses widgets of the GTK+ library as a GUI control kit.
TinyIDE is an IDE for C++ projects that is intended for use with SCons. It uses QScintilla as the editor component, supports workspaces with multiple projects, handles Qt's moc/uic handling, generates SCons scripts, supports multiple profiles (for example, for debug and release builds), and more.
OpenLDev is a development environment that provides a graphical front-end to Linux compilers such as gcc. It includes the basic essentials needed by a Linux programmer. It is a graphical interface to the collection of command line programming tools available for Linux and Unix systems.
U++ is a C++ cross-platform rapid application development suite focused on programmers' productivity without sacrificing runtime performance. Based on strictly deterministic design, it provides a viable alternative to garbage-collected platforms, even for business logic oriented problems.
Free Java is a development environment designed to help beginners write Java programs. Its editor includes syntax highlighting and an undo/redo function. It features a structure panel and a file browser. Compiling and running a program can be done with the push of a single button, and compiler errors are shown clearly. There is also a virtual console to show a program's console output. Free Java is based on J2SDK 1.3.
Cameleon is an integrated development environment for Objective Caml and eventually other languages. Its features include a graphical user interface, configuration management based on CVS, easy access to and browsing of documentation, various editors, customizable file types, a plug-in architecture, and a highly customizable interface.
