Fails to build under ghc-7.6.3 #12

Closed erikd closed 10 years ago

erikd commented 10 years ago

Building under 7.6.3 I get:

src/Data/ByteString/Builder/Scientific.hs:19:18:
    Could not find module `Data.ByteString.Lazy.Builder.Extra'
    Perhaps you meant
      Data.ByteString.Lazy.Builder.Extras (from bytestring-0.10.0.2)
      Data.ByteString.Lazy.Builder.ASCII (from bytestring-0.10.0.2)
      Data.ByteString.Lazy.Builder (from bytestring-0.10.0.2)

Does build correctly under 7.8.2.

Looks like 0.3 might need bytestring >= 0.10.4.

I tried to fix this, but @basvandijk hasn't pushed his commits to github :-(

Bas, would you like me to set up a Jenkins continuous build so you can tell if you're breaking the build for different flavours of GHC? Since attoparsec and aeson use it, incompatibilities in scientific have significant downstream consequences.

I just ran into this while I was following along in Chapter 4 of Beginning Haskell.

Anyone else following this book is going to run into this when they try to install the persistent package. Thankfully there's a workaround: just cabal install scientific-0.2.0.2 before trying to install persistent again. Still though, this package is pretty far upstream...

Fixed released as 0.3.0.1.

@bos if you have a jenkins running that I could piggy back on that would be much appreciated. Otherwise I might add a job on the jenkins I've setup at work.
