Either way, I did not want deps to be tested for coverage. Is this correct behavior that using --enable-coverage on cabal install should include deps in the mix file? It seems like that is never correct and for someone only using 'cabal install' it will never work for them. Also, it's unclear to me when to use -fhpc vs. --enable-coverage. Is there anywhere this is documented? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10259#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

So effectively you never want to use `cabal install --enable- coverage`. This is a Cabal issue, not a GHC issue. there anywhere this is documented? `-fhpc` is an option to GHC, and `--enable-coverage` is an option to cabal-install. If you use `--enable-coverage` then Cabal will take care of passing `-fhpc` to GHC. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10259#comment:5 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
