ncurses is proving too difficult to setup, so I'm working on a new library called charm. The C code works by itself, but I can't compile a Haskell wrapper for it. While the tutorials at <a href="http://www.haskell.org/haskellwiki/FFI_complete_examples">HaskellWiki</a> are helpful, they're outdated. Argh! The <a href="http://www.haskell.org/ghc/docs/latest/html/users_guide/ffi-ghc.html#glasgow-foreign-headers">docs</a> say that -#include pragmas no longer work, but fail to explain how to load code without them. Suffice to say I have no recourse but trial and error.<br>
