#8694: ghc -M doesn't handle addDependentFile or #included files ------------------------------------+------------------------------------- Reporter: simonmar | Owner: Type: bug | Status: new Priority: normal | Milestone: 7.10.1 Component: Compiler | Version: 7.6.3 Keywords: | Operating System: Unknown/Multiple Architecture: Unknown/Multiple | Type of failure: None/Unknown Difficulty: Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | ------------------------------------+------------------------------------- ghc -M doesn't emit dependencies specified by TH's `addDependentFile`, not does it emit dependencies for `#include`d files. The former is quite hard to do, because it requires compiling the code: we only have the information about `addDependentFile` calls after compilation. So in order to fix this, `ghc -c` would have to drop some information somewhere for the build system to pick up. In theory we should only have to preprocess files to get the list of #included files, and ghc -M already preprocesses all the files. However, currently #included files are picked up by the lexer during parsing, so fixing this isn't trivial. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8694 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
