#793: On OS X, warn about filenames that only differ in case ----------------------------+----------------------------------------------- Reporter: tibbe | Owner: Type: defect | Status: new Priority: normal | Milestone: Component: Cabal library | Version: 1.8.0.6 Severity: normal | Keywords: Difficulty: unknown | Ghcversion: Platform: | ----------------------------+----------------------------------------------- I managed to make Cabal fail to build a project by having {{{ Name: hamt Version: 0.1 License: BSD3 License-file: LICENSE Author: Johan Tibell Maintainer: johan.tibell@gmail.com Category: Data Build-type: Simple Cabal-version: >=1.2 Library Exposed-modules: HAMT Other-modules: PopCount Build-depends: base, vector C-sources: popcount.c }}} The result was: {{{ Building hamt-0.1... [1 of 2] Compiling PopCount ( PopCount.hs, dist/build/PopCount.o ) ld: duplicate symbol _popcount in dist/build/popcount.o and dist/build/PopCount.o for inferred architecture i386 }}} `_popcount` is only defined in `popcount.c`. Looking in `dist/` showed that there was only a popcount.o there (from the C file). Renaming `popcount.c` to `popc.c` solved the problem. Cabal ought to warn in this case. -- Ticket URL: http://hackage.haskell.org/trac/hackage/ticket/793 Hackage http://haskell.org/cabal/ Hackage: Cabal and related projects
