AccelerateCompat.hs compiling failed

[Jon Huang]

When i run the command below:

ghc -O2 fwaccel-gpu.hs -threaded

it states:

AccelerateCompat.hs:3:27:
     error: token is not a valid binary operator in a preprocessor subexpression
#if MIN_VERSION_accelerate(0, 14, 0)
    ~~~~~~~~~~~~~~~~~~~~~~^
1 error generated.

I googled it and found the solution here:

I need the flags "-optP-include -optPdist/build/autogen/cabal_macros.h" when run ghc:

ghc -O2 fwaccel-gpu.hs -threaded -optP-include -optPdist/build/autogen/cabal_macros.h
