Symbian OS Kits are designed to support Symbian licensees through all stages of development, from OS porting,
extension, and customisation, to application development.
The following components are required for all development and are supplied on the Symbian OS Development Kit:
Windows-based emulators supporting C++ development with industry standard compilers, currently Metrowerks CodeWarrior for Symbian Professional or Microsoft Visual C++ 6.0
emulators also support Java application development with standard Java tools as well as vendor tools specially targeting Symbian OS header files and libraries to support development for the emulators, and for ARM-based phones and development boards
a GCC-based compiler for building for ARM-based targets
additional tools for managing program building and deployment
Symbian OS source code to help debugging
documentation for the operating system and tools
Installation should be straightforward using the setup program on the Development Kit CD-ROM.
