Hey,
Thank you for the answer. Now I get:
ghc --make Test -o Test
Warning: output was redirected with -o, but no output will be
generated because there is no Main module.
How am I supposed to comple this file?

Nathan,
You must put the .hs on the input filename, but the '-o Test' isn't
necessary. So you can type
ghc --make Test.hs
I took a look at this file, and the module name is 'Test'. If you
change it to 'Main' it should work. I think this requirement was
tightened up in newer versions of ghc.

The .hs isn't necessary either. Here's the real answer: you simply
need to add a -main-is flag to tell ghc that the module containing
'main' is not called 'Main'. So:
ghc --make Test -main-is Test
should do the trick.

Thank you, Daniel!
I start to understand the issue.
Actually I could see the SCC pragmas you mentioned in the generated Core
- still without really understanding how all of them could have been hit
by a single run, but I'm sure I could figure that out once I really felt
the need to dig deeper into Core files...
For now I'll focus on the less esoteric aspects of Haskell. ;-)
Regards,
Thomas

Hey,
Thanks, it compiles now.
But when I run it, I get a empty window not updating itself ...
Does the Test.hs from reactive-fieldtrip run correctly anywhere else?
Is reactive-fieldtrip up to date or is it outdated? (The last update is
May 2009 ...).
Regards,
Nathan
