Hi
What version of GHC do you have? If its an old version you might need
to upgrade, if its a newer version (6.6) you might need to install the
mtl library (monad transformer library)
If you have any doubt please send the output from "ghc --version" and
I'm sure we can figure it out.
Thanks

I'm trying to build yhc on my debian machine. When I'm executing scons build, it reports the following error:
$ scons build scons: Reading SConscript files ... Building version 0.7.0-20061129043224-custom. Checking for architecture... (cached) x86 Checking for operating system...

What's the problem? Can anyone help me with it? _______________________________________________ Yhc mailing list Yhc@haskell.org http://www.haskell.org/mailman/listinfo/yhc
