[Haskell-cafe] Cabal: defaultMainNoRead and source file location

Hi, I've just seen this from Distribution.ModuleName (ghc 6.10): toFilePath $ ( simple "A.B.C" ) to which ghci answers: "A.B.C". Shouldn't it say "A/B/C"? The reason why I'm asking is that I've just created a Setup.hs with 'defaultMainNoRead', and 'Setup build' complains it can't find A.B.C. When I copy (move doesn't work) C.hs from /A/B to /A.B.C.hs, it doesn't complain, although it fails to generate my library saying: [1 of 1] Compiling A.B.C ( src/A/B/C.hs, dist/build/A/B/C.o) /usr/bin/ar: creating dist/build/libHSabc-0.a /usr/bin/ar: dist/build/A.B.C.o: No such file or directory Thanks for your tips, Maurício
