The Framework Database file must exist to specify the available packages in current workspace. + Two possible locations are: (The first location overrides the second) + $(WORKSPACE)\Tools\Conf\FrameworkDatabase.db + $(WORKSPACE)\Conf\FrameworkDatabase.db. + The field in FrameworkDatabase.db lists all available packages in current workspace. + One example: + + MdePkg/MdePkg.nspd + MdeModulePkg/MdeModulePkg.spd + IntelFrameworkPkg/IntelFrameworkPkg.spd + + The package list in FrameworkDatabase.db is important to the final quality of migration: + (1) It suggests the new package location: Translate package dependency Guid in MSA to Workspace relative path. + If the package dependency Guid cannot be found in current workspace a warning message is raised. + (2) It collects the Protocol/Guid/Ppi GuidCName a package contains. + The GuidCName acts as "clue" to add e.g. #include in CommonHeader.h + +5.
