ghc -M requires -dep-suffix for no good reason
Doing
ghc -M Foo.hsgives
You must specify at least one -dep-suffixI went to the documentation and noticed (7.8.12) an example:
depend :
ghc -dep-suffix '' -M $(HC_OPTS) $(SRCS)So, empty suffix is fine. Why not default to empty string then?
I found a commit which introduced the requirement (af072fc): it says, it fixed #7381 (closed), and this doesn't seem to do anything with dep-suffix in particular. So, maybe there is no good reason to require that.
