No your INF file lists the library class. The library class is the name of the library and the public header you code to. So an application/driver codes to a library class. The platform DSC files picks which library instances get used for each library class for every module type. For example different BaseMemoryLib (CopyMem) instance gets used for PEI and DXE as they are optimized for the environment. Did you add !include StdLib/StdLib.inc to MdeModulePkg\MdeModulePkg.dsc? [LibraryClasses.Common.UEFI_APPLICATION] ... LibTime|StdLib/LibC/Time/Time.inf It only resolves the mapping for modules of type LibraryClasses.Common.UEFI_APPLICATION. Are you building a driver? If you are not building an UEFI_APPLICATION then you need to add a , after LibraryClasses.Common.UEFI_APPLICATION and add your module type to get it to work. The module type you are using is in the part of the INF you did not include. [LibraryClasses.Common.UEFI_APPLICATION,[LibraryClasses.Common.UEFI_DRIVER] You could also add a DSC file to SpacelabsPkg and just build the things you car about.
