This documentation explains how to install Haskell binding for Unicorn
from source.
0. Install the core engine as dependency
Follow README in the root directory to compile & install the core.
On *nix, this can simply be done by (project root directory):
$ sudo ./make.sh install
1. Change directories into the Haskell bindings, build and install
$ cd bindings/haskell
$ cabal build
$ cabal install
If the build fails, try installing c2hs manually (cabal install c2hs) and make
sure that $HOME/.cabal/bin is on your PATH.
