#15837: Hadrian should build dynamically linked ghc binary -------------------------------------+------------------------------------- Reporter: davide | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Build System | Version: 8.6.1 (Hadrian) | Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: None/Unknown Unknown/Multiple | Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- The ghc binary is dynamically linked via make in various flavors (e.g. quick). Hadrian builds a static linked binary in these cases (this is a bug). Various change are needed to fix this: 1. Add new .cabal file field extra-dynamic-library-flavours (see [https://github.com/haskell/cabal/pull/5606 this PR]). 2. Use .cabal extra-dynamic-library-flavours for the RTS (see [https://github.com/snowleopard/hadrian/issues/695#issue-367436377 this comment], depends on 1.) 3. Hadrian: fix management of nontrivial dynamic flavours of libHSrts (see [https://github.com/snowleopard/hadrian/pull/698 this PR]). 4. Hadrian should build ghc with the `-fPIC -dynamic` options (see [https://github.com/DavidEichmann/ghc/commit/752021f69f577b678630302b567fd712... #diff-408bbe46d4afae11991cbadb2c531b78 this comment], depends on 3.). 5. Use the correct relative path to the dynamically linked libraries (see [https://phabricator.haskell.org/D5281 this change], depends on 3. and 4.). -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15837 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
