ghc -M

[Christian Maeder]

Hi,

using "ghc -M" with ghc-7.8.2 under linux. I got a message:

   You must specify at least one -dep-suffix

(and a failure).

http://www.haskell.org/ghc/docs/7.8.1/html/users_guide/separate-compilation.html#makefile-dependencies

I've stopped using "ghc -M" now, but I think it should be documented better.

Maybe dynamic linking complicated matters.

Cheers Christian
