llvm-general-pure fail at compilation

I want to install the "llvm-general" package from cabal. But the "llvm-general-pure" (dependencies) fail at compilation :

[19 of 28] Compiling LLVM.General.Internal.PrettyPrint ( src/LLVM/General/Internal/PrettyPrint.hs, dist/build/LLVM/General/Internal/PrettyPrint.o )

src/LLVM/General/Internal/PrettyPrint.hs:166:19: error:
    • The constructor ‘DataD’ should have 6 arguments, but has been given 5
    • In the pattern: DataD _ _ tvb cons _
      In the pattern: TyConI (DataD _ _ tvb cons _)
      In a case alternative: TyConI (DataD _ _ tvb cons _) -> (tvb, cons)

And some other error.

My configuration:

ghc -> 8.0.1

cabal-install -> 1.24.0.0

Any idea to fix it ?

Although the llvm-general-pure claims to work for base < 5, it does not support the GHC 8.0 changes to template haskell. In particular, the DataD constuctor used to take 5 arguments, but now takes 6. I have created a ticket on the project's GitHub page to bring this issue to the maintainer's attention.
