Carbide.c++ is a software development tool for C++ development on Symbian OS. It is used to develop phones that use the OS, as well as applications that run on those phones. It is based on the Eclipse IDE platform enhanced with extra plug-ins to support Symbian OS development. The product is provided by the Symbian Foundation under an open source model. In April 2009, Nokia transferred Carbide.c++ and many other software developer tools to the Symbian Foundation. Members of the Symbian community now manage and contribute code to the Carbide.c++ product.
