#217: .hsc files do not get processed for cabal sdist? ----------------------------+----------------------------------------------- Reporter: gwern | Owner: Type: defect | Status: reopened Priority: normal | Milestone: Cabal-1.4 Component: Cabal library | Version: 1.2.3.0 Severity: normal | Resolution: Keywords: | Difficulty: normal Ghcversion: 6.8.2 | Platform: ----------------------------+----------------------------------------------- Changes (by duncan): * status: closed => reopened * platform: Linux => * resolution: invalid => * milestone: => Cabal-1.4 Comment: Certainly putting .hs files in the extra-source-files is incorrect. There is a bug here however. The original description is inaccurate as it specifies {{{ main-is: Hslock.hsc }}} where the actual source at http://gorgias.mine.nu/repos/xmonad-utils uses {{{ main-is: Hslock.hs }}} This explains why the error message above is: {{{ Setup: Hslock.hs doesn't exist }}} So, `main-is:` should always be a `.hs` or `.lhs` file and is relative to the `hs-source-dirs:`. When building we correctly find the `src/Hslock.hsc` and pre-process it. The bug is that in sdist we just look for `Hslock.hs` directly in the `hs-source-dirs` without considering pre- processors at all. The current `Distribution/Simple/SrcDist.hs` code just does: {{{ withExe pkg_descr $ \ (Executable _ mainPath exeBi) -> do prepareDir verbosity targetDir pps [] exeBi srcMainFile <- findFile (hsSourceDirs exeBi) mainPath }}} So the mainPath is ignored for pre-processing purposes. -- Ticket URL: http://hackage.haskell.org/trac/hackage/ticket/217#comment:4 Hackage http://haskell.org/cabal/ Hackage: Cabal and related projects
