#9265: Extend PackageId to include version dependency information -------------------------------------+------------------------------------ Reporter: ezyang | Owner: ezyang Type: feature request | Status: new Priority: high | Milestone: Component: Package system | Version: 7.9 Resolution: | Keywords: backpack Operating System: Unknown/Multiple | Architecture: Unknown/Multiple Type of failure: None/Unknown | Difficulty: Unknown Test Case: | Blocked By: Blocking: | Related Tickets: -------------------------------------+------------------------------------ Comment (by rwbarton): What about packages that include "cbits" where the calling convention (or just semantics) of the C function changes from one version to the next? Won't the linker complain or, worse, just pick one? I guess with dynamic linking it might work. Admittedly, it could already happen that two unrelated packages use clashing names for their incompatible "cbits" C functions, but it seems rather more likely to occur between one version of a package and the next. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9265#comment:5 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
