Is the C library going to be a static (archive) or da dynamic (shared object) library?
If it is the latter then I think it would still work with comment:16 and if we pass a linker flag (something along the lines of copy all DT_NEEDED tags for C libraries from the dummy SO into the executable) the
Usually both, so that you can use `-optl-static` if you want. The `-dev` package of a C library normally includes both the unversioned `.so` and the `.a`. Remember that GHC links static Haskell packages but dynamic C libraries by default. performance impact would be small. Did you know the code in `Linker.lhs` is only used for GHCi and not linking of standalone executables? I have a suspicion that there's some confusion here. There is no "dummy SO" when linking a standalone executable. Since you have a design in mind, maybe it would be good to flesh it out in a wiki page so we can discuss with more precision? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9498#comment:25 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
