The Ecere SDK is a cross-platform toolkit for building software applications. It currently runs on Windows, Linux, (including Android), Mac OS X (through X11) and FreeBSD. 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.
