#15968: configure doesn't error out when --enable-dwarf-unwind is given but libdw cannot be found -------------------------------------+------------------------------------- Reporter: nh2 | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: 8.8.1 Component: Build System | Version: 8.6.2 (make) | Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: Other Unknown/Multiple | Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- Against expectations, the GHC bindist supposedly having DWARF support provided at https://downloads.haskell.org/~ghc/8.4.4/ghc-8.4.4-x86_64-deb9-linux- dwarf.tar.xz doesn't actually have DWARF support. According to bgamari, this is because `./configure --enable-dwarf-unwind` doesn't actually complain when the required dependency `libdw` isn't found; instead, it continues silently. Most programs I know will barf out when something isn't found but also *explicitly* requested via the command line; for the cases where this wasn't, the project maintainers did consider this a bug. GHC's `./configure` suite should fail hard when `--enable-dwarf-unwind` is given but `libdw` cannot be found. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15968 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
