#11587: Place shared objects in LIBDIR -------------------------------------+------------------------------------- Reporter: bgamari | Owner: Type: bug | Status: new Priority: normal | Milestone: 8.2.1 Component: Package system | Version: 7.10.3 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Runtime | Unknown/Multiple performance bug | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by duncan): Note that some more sharing is possible, given typical layouts. For example for nix or for cabal new-build we install into a store. {{{ $store/$pkgid-$hash/libHSpkgname-ver.so }}} (Currently it's actually worse than this since the libname includes hashes too, which should be unnecessary given the separated dirs) I'm not sure if this is possible with ELF, but if we can include part of the directory into the libname / location, and a separate RUN_PATH then we could use a scheme like: {{{ RUN_PATH /home/me/.cabal/store SO_NEEDED pkgname-ver-hash/libHSpkgname-ver.so SO_NEEDED ... }}} This does appear to be possible with MachO, ie like: {{{ LC_RPATH /home/me/.cabal/store LC_LOAD_DYLIB @rpath/pkgname-ver-hash/libHSpkgname-ver.dynlib }}} -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11587#comment:7 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
