Dear Pepe,
Thank you for the information. I finally ended up working with Debug.Trace, and found the bug very quickly. I also tried Hood, but couldn't load it in ghci: import Observe can't find the library, but
% locate Observe /usr/lib/ghc-6.4.2/hslibs-imports/util/Observe.hi /usr/lib/ghc-6.4.2/hslibs-imports/util/Observe.p_hi /usr/lib/hugs/libraries/Hugs/Observe.hs /usr/lib/hugs/oldlib/Observe.hs
Does importing from hslibs-imports require something special?
Hi Tamas I'm glad to hear that you fixed it! GHC includes Observe (the hs-libs-imports file you are seeing) only in the hidden 'util' package, which I believe is deprecated or not present in 6.6. If you want to use it, launch ghci with the flag '- package util'. Or download Observe.hs from the Hood website and place it somewhere in the path. Hmm, it would be handy to have a Cabal Hood package... Cheers pepe
