Cannot make ghc: Failed to load interface for GHC.Base

[Simon Peyton-Jones]

Wait.. are you saying that with HEAD several test suite programs fail as you describe below?  If so, which?

Closed, but a note to interested readers:

killy9999 on #ghc realized the reason why the stage1 compiler cannot be built with this patch is related to that several test suite programs exit with erros like this:

GHC/Base.lhs:1:1:

    GHC internal error: ‛GHC.Base.Monad’ is not in scope during type checking, but it passed the renamer

    tcl_env of environment: []

So the error is resolved, and now productive debugging can start.

Sorry! I thought I got this build error when making HEAD, but I don't. It builds fine.

However, if I just cherry-pick this simple commit onto HEAD
https://github.com/danr/ghc/commit/86631ffd294af320cb9b00e1a593201af887ed72,
then I do get this error, which is very puzzling. I did a make maintainer-clean in between.

I tried all of clean, distclean and maintainer-clean, followed by the
usual build process. The issue remains.
