I'm trying to use CPP-defined strings in a Haskell module, like this: main :: IO () main = putStrLn FOO This of course will not work: ghc -DFOO="hello world" --make Main.hs -o test

Have you tried using ANSI cpp's stringification operator?

{-# LANGUAGE CPP #-} #define STRING(bar) #bar main :: IO () main = putStrLn FOO

ghc -DFOO="STRING(hello world)" --make Main.hs -o test

Yes, I have. It does not seem to be supported.
