Ticket #7373 (new bug)
When building GHC: Failed to load interface for `GHC.Fingerprint'

|Test Case:||T7373||Blocked By:|
when doing a build with THREADS=1, we are getting things like:
inplace/bin/ghc-stage1 [...] -c libraries/time/./Data/Time/Calendar/Days.hs [...] /home/ian/ghc/git/ghc/libraries/base/dist-install/build/Data/Typeable/Internal.dyn_hi Declaration for mkTyConApp Unfolding of Data.Typeable.Internal.mkTyConApp: Failed to load interface for `GHC.Fingerprint' Perhaps you haven't installed the "dyn" libraries for package `base'? Use -v to see a list of the files searched for. /home/ian/ghc/git/ghc/libraries/base/dist-install/build/Data/Typeable.dyn_hi Declaration for mkTyCon Unfolding of Data.Typeable.mkTyCon: Can't find interface-file declaration for variable GHC.Fingerprint.fingerprintString Probable cause: bug in .hi-boot file, or inconsistent .hi file Use -ddump-if-trace to get an idea of which file caused the error
(we only have Fingerprint.dyn_hi-boot). GHC still exits successfully, however.
