Yes, runghc is actually a small Haskell program that shells out to ghc -e.

I filed an issue:  https://ghc.haskell.org/trac/ghc/ticket/10261

No, it's not supposed to work, since runghc interprets GHC code.
runghc itself is just a little shell script which calls GHC proper
with the -f flag, so I suppose the build system was just not set
up to not create this link in that case.

Excerpts from Jeremy's message of 2015-04-06 07:34:34 -0700:
 I've built GHC with GhcWithInterpreter = NO. runghc is built and installed,
 but errors out with not built for interactive use.
 
 Is runghc supposed to work with such a build? If not, why is it built at
 all?

runghc and GhcWithInterpreter

2015-04-06 Thread Jeremy
I've built GHC with GhcWithInterpreter = NO. runghc is built and installed,
but errors out with not built for interactive use.

Is runghc supposed to work with such a build? If not, why is it built at
all?
