I tried to compile my program with -prof, but GHC just whines at me that the packages I'm using haven't been compiled for profiling. Do I really need to go recompile every single package I'm using with profiling support before I can profile my program? How do I tell Cabal to install the necessary code? (I really hope this doesn't involve uninstalling and reinstalling everything...)
Almost. You don't need to uninstall anything, just run cabal install <package> --reinstall -p for every relevant package.
Oh, right. So I actually need cabal.exe to do this then?
No, you can also $ ./runghc ./Setup.[l]hs configure --enable-library-profiling --user -- prefix=$HOME/.cabal $ ./runghc ./Setup.[l]hs build $ ./runghc ./Setup.[l]hs haddock --hyperlink-source $ ./runghc ./Setup.[l]hs install It's just more typing [protip: create a batch file (that is the Windows analogue of a shell-script, isn't it?)].
