Hello all! I recently upgraded my development platform to GHC 7.0.3 and the latest platform. After manually patching the cabal package for DrIFT (it had a dependency base<4 which was not satisfiable on my system, so I changed it to base-all) I tried to build jhc. Both version 0.7.7 fail to build, but there are different reasons: - -XTypeFamilies is required to build JHC with GHC 7.0.3, so I added this flag to Makefile.am - jhc 0.7.7 fails to build at the module "Options" with the following error message: [ 73 of 169] Compiling Options ( drift_processed/Options.hs, src/Options.o ) src/Options.hs:396:19: Couldn't match expected type `[Char]' with actual type `Char' Expected type: [String] Actual type: [Char] In the second argument of `(==>)', namely `version' In the expression: "version" ==> version - jhc TRUNK fails at E.SSimplify with a rather long error, so I put it onto a paste service: http://goo.gl/tpKvZ I hope these errors are helpful. Yours, Robert Clausecker
