[Haskell-beginners] debugging help

[Thomas Jakway]

I wouldn't approach this from that perspective.  If it's just a small 
codebase you might want to just grep -R "printf" . and look through each 
statement.  To be honest I've never really used ghci for debugging (I'm 
definitely a beginner) but getting a stack trace seems like overkill and 
I'd be willing to bet ghci would be more productive anyway.  If you 
really want to though the flag is -prof. To compile the library with it 
you could edit the .cabal file and add it under ghc-options.
or cabal build --ghc-options="-prof" would probably also work.

(if I'm wrong about any of the above I'd really appreciate it if someone 
more experienced than me would correct me so I don't make the same 
mistakes!)
