#10352: Properly link Haskell shared libs on ELF systems -------------------------------------+------------------------------------- Reporter: duncan | Owner: Type: task | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.11 (Linking) | Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: 5987 Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by trommler): Just an idea: The RTS is split into two parts, a small stub library and the actual RTS library (respectively its flavours). The stub library checks for an RTS parameter or an environment variable or ... to determine the flavour of RTS desired. The stub library `dlopen`s the appropriate shared library with `RTLD_GLOBAL` scope, which makes all RTS symbols available to all shared libraries loaded after. The linking of the stub RTS results in dangling references which is fine for ELF shared libraries. Perhaps, the functionality of the stub library could also be integrated into hs_init(). In that case libraries depending on the RTS must not be linked against any flavour of the RTS resulting in dangling references. That is fine in ELF. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10352#comment:9 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
