I’ve just cloned GHC, on Windows and typed “sh validate”.  But it dies as below.  And indeed the directory ghc-tarballs doesn’t exist.  Should it?  How do I get it?


git clone git://git.haskell.org/ghc-tarballs.git
As described on the wiki: https://ghc.haskell.org/trac/ghc/wiki/Building/GettingTheSources#CloningHEAD

There is an unfinished patch to make that step unnecessary: https://phabricator.haskell.org/D339
