#15197: Apparent missing dependency in ghc-heap -------------------------------------+------------------------------------- Reporter: bgamari | Owner: (none) Type: bug | Status: new Priority: highest | Milestone: 8.6.1 Component: Compiler | Version: 8.4.3 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by bgamari): The problem is apparently that the import of `InfoTableProf` is guarded behind a `#if defined(PROFILING)`: {{{#!hs #if defined(PROFILING) import GHC.Exts.Heap.InfoTableProf #else import GHC.Exts.Heap.InfoTable #endif }}} Looking at the GHC-generated dependency file I see the following, {{{#!make libraries/ghc-heap/dist-install/build/GHC/Exts/Heap/Closures.p_o : libraries/ghc-heap/dist-install/build/GHC/Exts/Heap/InfoTable.p_hi }}} It looks to me like `ghc -M` isn't correctly accounting for ways when generating its dependency graph. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15197#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
