The SDK support of Carbide.c++ allows you to use the SDK seamlessly with the IDE. Once you have installed Carbide.c++, it automatically locates the relevant SDK information, such as, header files, import libraries and documentation, which are then accessible through the IDE.
You can also use multiple SDKs with Carbide.c++. These are managed through the SDK Preferences tool of the Carbide.c++ IDE (go to Window > Preferences... > Carbide.c++ > SDK Preferences), which enables you to scan for new SDKs on your PC, add new SDKs to the list of SDKs supported, as well as remove SDKs from the list.
For more information, please refer to the Carbide.c++ Help (Carbide.c++ User Guide > Symbian OS Projects > Concepts > SDK Support).
