Problems building on ghc-7.8.4 about bake HOT 6 CLOSED

Actually base-4.8 and higher should be high enough.

Are you using bake from HEAD or Hackage? I strongly recommend the HEAD version.

You can't mix and match GHC versions and base versions - there's no way to change the base version installed, so I don't see how your base/GHC can get out of alignment. I've just run the buildbot (https://travis-ci.org/ndmitchell/bake) and it successfully compiles on 7.6 to GHC Head (the errors are all due to insufficient doc comments), so I guess the question is what is different with your setup. Which version of transformers do you have? Any chance it is 0.3 or before? If you upgrade to a newer one that should probably work. If that works for you, I'll change the bounds. If not, I can write those instances by hand and we can avoid the transformers-0.4+ dependency.

I'll have a look later. BTW how did you get around compiling cryptonite on that special, old red hat box? I'm getting cc1: error: unrecognized command line option "-maes", I assume due to an old gcc...

Mostly by asking @vincenthz, I also wrote it down on the JIRA related to Hoogle. I think the magic was something like -fold_toolchain_inliner when configuring cryptonite.

I was on transformers-3. I've upgraded to 0.5.2.0 and everything is now working :-)

Dependency added. Let me know if you have any other problems.
