New to Haskell AND FranTK I am trying to install both. So far I have:

1. installed Hugs98 (seems to work)
2. installed TCL/TK (demos work fine)
3. installed FranTK

that is were I am stuck. Since I am running Windows, I have modified
tclhugs98.bat to point to the right directories.

When I start

tclhugs98 ..\demos\demos.lhs

Hugs is really starting to load the files, but when it reaches
frantk/src/TclHaskellSrc/Utils.hs it halts with the following message:

ERROR "F:\Haskell\frantk\src\TclHaskellSrc\Utils.hs":61 - Definition of
variable "updateIORef" clashes with import

Variable updateIORef is indeed mentioned in the file BaseTypes.hs, and IORef.hs, which are
loaded earlier on.

I tried commenting updateIORef out of IORef.hs. That helps to load another dozen files or so.

But then it hangs again, this time with the message:

ERROR "F:\Haskell\frantk\src\FranSrc\MutSet.hs":40 - Cannot use type synonym in instance head

Now I am really stuck.

Has anybody managed to run the FranTK demo? Why is trying to start Hugs in Hugs-mode rather then Haskell98?

I am grateful for any help .

Cheers,
Stephan
