[ 1 of 13] Compiling FRP.Yampa.VectorSpace ( FRP/Yampa/VectorSpace.hs, dist/build/cuboid/cuboid-tmp/FRP/Yampa/VectorSpace.o )

FRP/Yampa/VectorSpace.hs:51:22: error:
    • Could not deduce (Eq a) arising from a use of ‘/=’
      from the context: VectorSpace v a
        bound by the class declaration for ‘VectorSpace’
        at FRP/Yampa/VectorSpace.hs:(32,1)-(53,23)
      Possible fix:
        add (Eq a) to the context of
          the class declaration for ‘VectorSpace’
    • In the expression: nv /= 0
      In the expression:
        if nv /= 0 then v ^/ nv else error "normalize: zero vector"
      In an equation for ‘normalize’:
          normalize v
            = if nv /= 0 then v ^/ nv else error "normalize: zero vector"
            where
                nv = norm v
