Hello!
I'm using GHC 7.10.3 after an upgrade. I have the following in my Makefile:
depend_mod :: lib/abh ghc -M $(CFLAGS_GHC_0) -dep-makefile -optdepbuild/depend.tmp -dep-suffix "p_"
You should drop the -optdep here
\ $(foreach m, $(MOD_HS) $(PROG_HS), src/$(m).hs) \ $(foreach m, $(MOD_CHS) $(PROG_CHS), build/$(m).hs) ...
This used to work. The previous GHC version was 7.8.
As a side effect of finally removing the -optdep-f flag, https://ghc.haskell.org/trac/ghc/ticket/2773 (another relevant commit is 994d5e3cfc32cb624b63683205dd8fd876171d0c) the code that strips -optdep from the filename, which was required to make -optdep-f -optdepfoo work, also got removed. The fact that -dep-makefile continued to strip -optdep was an accident in my view. Cheers, Bertram
