#584: adding arbitrary .o files to the static archive ----------------------------+----------------------------------------------- Reporter: wisnesky | Owner: Type: enhancement | Status: new Priority: normal | Milestone: Component: Cabal library | Version: 1.6.0.1 Severity: normal | Keywords: Difficulty: unknown | Ghcversion: Platform: | ----------------------------+----------------------------------------------- Cabal's Simple build system does not currently provide any mechanism for adding arbitrary .o files into the static archive and similarly no way to link one static archive with another. The only builtin mechanism is to compile C code (specified by the "c-sources" field) and that gets included into the same static archive as the Haskell library. I would like to request this feature. Here is a more detailed description: Adding an extra-libraries field to a cabal source package description: {{{ Name: LibraryFoo ... Library Extra-libraries: Bar }}} has the effect that when loading package LibraryFoo in ghci, ghci will necessarily try to open a corresponding Bar.so/.dll/.dylib file: {{{

ghci -package LibraryFoo Loading package LibraryFoo-0.1 ... <command line>: can't load .so/.DLL for: Bar (dlopen(Bar.dylib, 10): image not found) }}} What I want to do is statically link LibraryFoo against Bar before Cabal installs the package, (so that, for instance, I can run ghci without a bunch of command line linking arguments and don't need to have Bar around anymore), and I have a Bar.o file for just such a purpose.
