Hi all
If I want to give warnings when doing something and I don't care too
much about the order they appear in, can I use this?
foo x = if success x then Just x
else warn "Working out x went wrong" Nothing
warn :: String -> a -> a
warn s x = unsafePerformI
The graphics lib of the new December release does not
compile with the shipped makefile.
The makefile does not do anything at all???
Maybe there is a problem with wildcard extensions?
To be honest, I have no clue. I am using a Sparc5/Solaris
machine.
Any help appreciated.
Thanks in advance,
B
