Is there a way to use Hat with GHC, without 'hmake'?
Sure, you can make all calls to hat-trans and ghc directly yourself, but that is rather cumbersome. You cannot use anything like ghc --make, because ghc doesn't know about Hat.
The Hat Tutorial shows 'hmake' being used, but 'hmake' doesn't work for me. The problem is that 'hmake' seems to be looking for 'ghc' based on something other than PATH:
hmake uses its own little database of compilers. You can tell hmake about the compiler through hmake-config add ghc hmake-config default ghc http://www.haskell.org/hmake/hmake-config.html gives more details.

Fail: Can't find module Graphics.X11.Xlib in user directories
This indicates that you will run into a more serious problem. Hat currently only supports a limited set of libraries and Graphics.X11.Xlib is not among them. If an unsupported library is just a normal Haskell module, a simple solution is to copy it into the same directory as your own code (modify the module name accordingly) and just treat it as part of your program. However, this soon becomes more complicated if the library requires further modules and special link options. Ciao, Olaf
