BNFC install error

Question

I am trying to install BNFC on my Mac (Running OS Sierra). I have already installed the Haskell Platform for Mac (v.8.0.1) I have installed cabal then used that to install alex (v 3.2.1) and happy (v 1.19.5). I then ran the cabal install bnfc and that installs properly. The problem is as soon as I type bnfc or try using any bnfc commands I get:

-bash: bnfc: command not found

Is there something I am missing here? When I try installing BNFC again I get:

All the requested packages are already installed: BNFC-2.8.1

Any ideas? Thanks!

The Haskell Platform should already come with alex and happy. cabal installs binaries to ~/.cabal/bin by default, which may not be on your PATH.

How do I go about adding that to my PATH? – Will Nov 25 '16 at 12:16
Depends on the shell you use. For bash, you'd normally add a line such as `export PATH="~/.cabal/bin:$PATH"` to the end of your `.bashrc`. – kosmikus Nov 25 '16 at 15:45

Ended up copying across the files (alex, bnfc and happy) from

/Users/username/Library/Haskell/bin

to

/usr/local/bin/

and all working now
