Here is my tale of woe. I'm running this on Mac OS X 10.6.
I tried to install the syb-with-class package off of hackage, which
initially failed because of the changes to the template-haskell
package installed with 6.12.1rc1.
So I think to myself "Oh! I'll just put an upper bound on the version
of template-haskell used in the .cabal file for syb, and install the
old version off of hackage".
The current version of template-haskell installs fine on 6.12.1rc1
with a couple minor tweaks (to compensate for StringConstr not being
present in Data.Data anymore).
But then when I try to build syb-with-class against the old
template-haskell lib I get the following error:
$ ./Setup build
Preprocessing library syb-with-class-0.5.1...
[3 of 4] Compiling Data.Generics.SYB.WithClass.Derive (
Bad interface file:
Something is amiss; requested module
template-haskell-126.96.36.199:Language.Haskell.TH differs from name found
in the interface file template-haskell:Language.Haskell.TH
Has anyone seen this before? Are there any tools I can use to peer
into .hi files to get more information about what could be wrong?
