Inline-r does not build with cabal

[Rodolpho Pueyrredón]

Hello guys. I'm having trouble installing inline-r with the cabal. My system is Windows 10. Also occurs on windows 7

The commands I use are:

cabal sandbox init

cabal init

cabal install c2hs

cabal install inline-r==0.9.* --extra-include-dirs="C:/Program Files/R/R-3.4.2/include" --extra-lib-dirs="C:/Program Files/R/R-3.4.2/bin/x64"

The error:

src\Control\Monad\R\Class.hs:36:11: error:

    * The default type signature for acquire:

        forall s (a :: SEXPTYPE).

        (MonadIO m, Region m ~ G) =>

        SEXP s a -> m (SEXP G a)

      does not match its corresponding non-default type signature

    * When checking the class method:

        acquire :: forall (m :: * -> *).

                   MonadR m =>

                   forall (a :: SEXPTYPE). SEXP V a -> m (SEXP (Region m) a)

      In the class declaration for `MonadR'

   |

36 |   default acquire :: (MonadIO m, Region m ~ G) => SEXP s a -> m (SEXP G a)

   |           ^^^^^^^

exception was:

somebody save me!!

I was able to solve the problem. It was ghc compiler compatibility with the package. But now I have another. When I import H.Prelude it occurs:

*** Exception: R: readCreateProcess: does not exist (No such file or directory)

Hello Rodolpho!

It seems that R executable is not in your path. I see that you have installed it because otherwise it would not be possible
to install inline-r and H. However it seems either ghci or R is not in your %PATH%.
Currently the only thing that creates process is H executable and it calls ghci, no other part of the code is starting
process. Can you check if ghci and R are in your %PATH%?

Can you also describe the actions you are doing so I could try to reproduce the problem?
