[Haskell-beginners] Missing C libraries on windows

[Elise Huard]

Hi Cameron,

which error message do you get?
I've hacked my way through such issues by manually adding an
extra-lib-dirs:
with the _absolute_ path in the executable or library section of the
cabal file, so that could be something to try.  It's not a final
solution obviously, but it would allow you to check whether it works
at all.
An example on github of this
