Re: [Haskell-cafe] Overriding CPP preprocessor on OSX

I'm having some problems[0] with the derive-storable package on OSX I don't have on Ubuntu. I would like to use g++ rather than clang to preprocess CPP code. Is there a way to do this with cabal?

Thanks!

You can go a step further and avoid depending on cpp from any of the big C compilers! Add `hpp` to your `build-depends`, and add this to your .cabal file, ``` ghc-options: -pgmPhpp ``` Then if the preprocessor does something untoward, we can actually fix it! Or you can use the same style of `ghc-options` flag to call gcc's cpp. Anthony
