Hi Sean, it looks like your Focus module is not interpreted and thus has no breakpoints. (that error message could be easily improved to let you know this) The ghci debugger only works with interpreted code, you can either delete all the *.hi and *.o temporary files or simply use the flag -fbyte-code to ensure that ghci loads the code in interpreted mode. By the way, the ghci debugger has a few quirks more. You probably want to give a read to the debugger docs in the GHC manual if you plan to use it for anything non trivial.

Hello,
I'm having trouble setting breakpoints from ghci. I load the files and I can tell things are working correctly because I can run the program and list the locations where I want to set breakpoints. E.g.
Prelude> :list Focus.focus 510 > focus :: forall s m. Class s m => Neg -> m [Foci] 511 > focus f = 512 > let ats = Path.atoms f
But when I try to set a breakpoint I get
Prelude> :break Focus.focus No breakpoints found at that location.
Does anyone have ideas about what I'm doing wrong in this case? Do I need to load with some special options to have breakpoints work?
Thanks,
