Hi all, I'm running under Windows XP/cygwin and have the Haskell Platform/GHC 6.10.4. I thought I'd have a look at FieldTrip. If I run "cabal install FieldTrip" I get an error (see below) relating to Vector2. Any advice? By the way, GLUT programs run OK; apparently now even without explicit library linking (ghc --make file.hs) Cheers, Paul ...
