The library is very much a work in progress.

Haskell interface to the FLTK window toolkit

* Built using Cabal with hacks.
* For more information about FLTK see
* Porting to windows should be possible, but I don't have the resources to do it.


* A very recent version of Cabal is needed
  * 17.11. support for C-Sources in subdirs
  *  6.12. Extra-Lib-Dirs support - not necessary on all platforms.
* Works with both GHC 6.2 and the CVS version of GHC.
* FLTK 1.1 headers and library
* No direct dependency on libstdc++ although libfltk does depend on it.
  This is to avoid issues with linkers doing nasty things.


* Download and unpack.
* Build and install through Cabal as for other Haskell packages:

      runhaskell Setup configure --user --prefix=$HOME
      runhaskell Setup build
      runhaskell Setup install --user

(You may want to remove the --user flag when installing as root.)

* see example/
* library errors are most likely due to missing symlinks
  e.g. ->, if someone knows how to fix this
  with Cabal please tell.


* GHCI support is broken due to GHC not supporting weak (W) symbols properly.
* The Hugs Debian package is not usable.
