Hi list. I'm trying to cabal install a few different packages and keep getting this error: ghc: unrecognised flags: -I I've looked at the documentation for ghc online and there seems to be a -I flag for letting the c-preprocessor know where to look for included libraries. For example, "cabal install -v logict" generates the following partial output: /opt/local/bin/ghc -package-name logict-0.3 --make -hide-all-packages -i -idist/build -i. -idist/build/autogen -Idist/build/autogen -Idist/build -I -optP-include -optPdist/build/autogen/cabal_macros.h -odir dist/build -hidir dist/build -stubdir dist/build -package base-3.0.3.1 -package mtl-1.1.0.2 -O -O2 -Wall -XMultiParamTypeClasses -XUndecidableInstances -XRank2Types -XFlexibleInstances Control.Monad.Logic Control.Monad.Logic.Class ... which then triggers the "ghc: unrecognised flags: -I" error and aborts the installation. Is this an issue with particular versions of GHC or something? I'm running: Glasgow Haskell Compiler, Version 6.10.4, for Haskell 98, stage 2 booted by GHC version 6.8.2 Thanks for your help. - Lyndon
