I just updated my GHC HEAD copy via git pull and tried to rebuild GHC with BuildFlavour set to devel2. I got the following error message:
ghc/InteractiveUI.hs:68:8: error: Could not find module ‘Control.DeepSeq’ It is a member of the hidden package ‘deepseq-1.4.1.1@deeps_6vMKxt5sPFR0XsbRWvvq59’. Use -v to see a list of the files searched for.
Any ideas what to do?
...have you ./boot'ed and ./configure'd again (and to be on the safe side, also 'make distclean')? This sounds as if your ghc/ghc-bin.cabal wasn't regenerated from the .in file...
The page at https://ghc.haskell.org/trac/ghc/wiki/Building/Hacking says that just running make again is enough. Also, I do not want to run make distclean, of course, since I want the rebuild to be fast. All the best, Wolfgang
