Hi,
I am trying to build this project (master branch). I am on ghc 7.10.
I am using sandbox, and I think there is no issues with installation.
While building I get these errors
Can anybody please help.

I've seen similar errors before when using a version of llvm that's not compatible with the version of ghc. What version of llvm are you using? You can use the following command to check:

$ opt --version
LLVM (http://llvm.org/):
  LLVM version 3.5.2
  Optimized build with assertions.
