Here's how to fix installation with new Cabal

[alan-j-hu]

Hi there,

To fix the installation issues with new-style Cabal, you can either:

• Replace build-type: Custom with build-type: Simple in Euterpea.cabal
• Add the following to Euterpea.cabal:

custom-setup
  setup-depends: Cabal, base

If Setup.hs needs any dependencies other than Cabal and base, use build-type: Custom and list the dependencies; otherwise, use build-type: Simple.

See #26 (comment).

I've wanted to use this library for so long, but could never get it working with Cabal. Now that I know what the problem is, I look forward to being able to build and use it! Thank you for your work maintaining Euterpea!

@donya I have just started reading "The Haskell School Of Music", I am a beginner in Haskell and am hoping to use your book to learn, only to encounter this cabal issue.

After looking at your open issues and PR's I went to make one myself, only to notice that the README says you don't accept PR's and changes will be managed by open issues.

I realise that there might be a reason why this has not been fixed for later versions of cabal that I would not understand due to my noobie view of the Haskell / cabal eco system but could you please advise when this will be fixed or why it can not?

In the meantime, I'm going to work out how to build/install the library from source.

[EDIT]
Just found Haskell Platform 8.6.5 install notes.

cabal v1-update
cabal v1-install Euterpea

Worked a treat.
