As mentioned by David Terei in March 2013 (https://www.haskell.org/pipermail/ghc-devs/2013-March/000677.html) you now have to write `ghc -M [files] -dep-suffix=''` to get the old `ghc -M [files]` behaviour. This hit me badly since I was using some other `-dep-suffix` flags already, so I didn't get the `"You must specify at least one -dep-suffix"` warning, and the `.o` files were simply missing from my output Makefile. I'm reopening this ticket so that we can mention this change at least in the changelog for 7.8.4 if that's OK. And as David wrote, the user guide should probably also be updated. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/7381#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
