Thanks, moving the file to src/semanticdb/OSIX works. However, I would prefer it if restructuring my directories weren't necessary. Is it possible?

No, the hierarchical module names map directly to the directory structure, module A.B.C must be in the file C.[l]hs in the directory A/B, viewed from the root of the source tree (the directory you name in hs-source-dirs).

Ah, actually I misremembered, according to

http://hackage.haskell.org/trac/haskell- prime/wiki/DottedHierarchicalModules

you can also have the file with dots in the filename.

Mmm, I tried it out but it doesn't seem to work for me. I found this extensions support matrix on http://hackage.haskell.org/trac/haskell-prime/wiki/HaskellExtensions that indicates that GHC doesn't support DottedHierarchicalModules. It appears to be a JHC extension...
