Integration overview

How ClearCase VOBs and Views are realized in SNiFF+
ClearCase VOBs (Versioned Object Bases) contain all public ClearCase data. This data can either be shared object or shared source data. ClearCase Views are private storage areas that access VOBs. The contents of a VOB can only be "seen" through a private View that accesses it.
In SNiFF+, ClearCase Views correspond to Private Working Environments (PWEs). There is no SNiFF+ equivalent to a VOB.
To view and work with the elements (source files and directories) of a VOB, you first have to create a PWE for the View with which you access the VOB. Then, you can open SNiFF+ projects in the PWE that contain the files you're interested in. If the projects don't exist, you first have to create them.
(Creating projects for ClearCase are discussed under Setting up a SNiFF+ project with ClearCase.)
How builds are performed in SNiFF+
You can use both standard Make and clearmake for building object files in your PWE. The appropriate Make command can be set in the Project Attributes dialog.
Shared Object Working Environments are also unnecessary when using clearmake, because clearmake's wink-in feature handles how object files (ClearCase DOs) are shared between views.
