#7478: setSessionDynFlags does not always work -------------------------------------+------------------------------------- Reporter: edsko | Owner: Type: bug | Status: new Priority: high | Milestone: 7.12.1 Component: Compiler | Version: 7.7 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: None/Unknown | Unknown/Multiple Blocked By: | Test Case: ghc- Related Tickets: | api/T7478 | Blocking: | Differential Revisions: -------------------------------------+------------------------------------- Comment (by bherzog): A better solution is the following, I think: Have `defaultFlags` include `Opt_Static` in its result if `pc_DYNAMIC_BY_DEFAULT` is False. Reasoning: comment:17 shows that `ways` and `generalFlags` need to be coordinated wrt. dynamic/static linking: `generalFlags` needs to contain `Opt_Static` exactly when `ways` does not contain `WayDyn`. The values of both fields are derived from the settings passed to `defaultDynFlags`. In particular, `ways` will either be `[WayDyn]` or `[]`, depending on whether `pc_DYNAMIC_BY_DEFAULT` is True or False respectively. Therefore, `defaultFlags` should include `Opt_Static` in its result if `pc_DYNAMIC_BY_DEFAULT` is False. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/7478#comment:18 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
