Hi there,

The only version of template haskell which will work is the version that the compiler was built against. So if you're working with ghc-7, it is 2.5 or nothing.

Why doesn't HStringTemplate work with 2.5.0.0? What error were you getting?

Hi,  I am trying to make happstack work in my box, which is using ghc 7.  While compiling HStringTemplate, which I did a little modification to make it work, I found that it does not work with template-haskell-2.5.0.0. I changed it to use template-haskell-2.4.0.1. This step worked fine.  Then I got another error: $ cabal install Resolving dependencies... Configuring syb-with-class-0.6.1.1...

I see. The building problem with 2.5.0.0 is Language.Haskell.TH.Quote.QuasiQuoter. It changed from 2 params constructor to 4 params. And I have no idea how to give the 2 new params. -- 竹密岂妨流水过 山高哪阻野云飞
