So, in GHCi, how do I successfully import a submodule that needs to import some other submodule in the module?
[~/Geometry]$ cd .. [~]$ ghci
import Geometry.Sphere
Hi Daniel, Thank you for your suggestion. It appears that your suggestion partially works. Picking up from where I left off previously: Prelude> :q Leaving GHCi. [~/Geometry]$ cd .. [~/]$ ls Geometry/ clang-xcode5-wrapper.hs test.hs [~/]$ ghci GHCi, version 7.6.3: http://www.haskell.org/ghc/ :? for help Loading package ghc-prim ... linking ... done. Loading package integer-gmp ... linking ... done. Loading package base ... linking ... done. Prelude> import Geometry.Sphere <no location info>: Could not find module `Geometry.Sphere' It is not a module in the current program, or in any known package. Prelude> :load Sphere <command line>: Could not find module `Sphere' Use -v to see a list of the files searched for. Failed, modules loaded: none.

But by trying “:load" from the parent directory, I was able to load Sphere, Cube and Cuboid. The problem is that it appears that only one is available at a time (i.e. loading Cube displaces Sphere). What’s more there is no way to do qualified imports. Regards, James
