Hi,

I tried to use unboxed arrays for generating an antialiased texture. To make it easier to understand, here is the stripped down code that produces an error:

What do you think?

It is generally acknowledged that the array types bundled with GHC have serious shortcomings, such as for example the one you just pointed out. There is not, however, a consensus on how to change them. To solve your particular problem, I would suggest looking up the storablevector package on Hackage, which I know can handle arbitrary unboxed elements. That said, I'm sure someone will be along shortly to give you the full story. :-) -- Svein Ove Aas
