Agreed. The issue with the fibon folder as a whole is a lot of the
benchmarks have substantial dependencies as they are taken from
Hackage to represent real world programs. This is handled in a very
ugly fashion right now by just including a copy of the source of all
dependencies. So overtime it will always break as GHC and base
Shootout and some of them though don't have dependencies, so we should
look at moving them out of the fibon folder and enabling them by
default. After that we can look at better ways to handle the
dependencies of the remaining fibon benchmarks.
Why are you creating new shootout benchmarks though rather than simply
move the exiting Shootout folder from fibon/Shootout to the top level
and fixing the makefile?
Some of this discussion going forward may make more sense on trac.
There is trac ticket for improving nofib in general here:
