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.
TSDL was written for the turn-based strategy game "Turious", but is a stand alone library. It provides a number of useful widgets and event handling functions. Its widgets include container, label, button, text, numbox, checkbox, and console. All of the widgets can be given individual background images and custom text. Containers and widgets can be shown and hidden individually, and will retain their visibility state. The library uses OpenGL for rendering, allowing it to be used in 3D games as well as 2D.
