- # About the options used for Darwin:
- # -dynamiclib
- # Apple's way of saying -shared
- # -undefined dynamic_lookup:
- # Without these options, we'd have to specify the correct dependencies
- # for each of the dylibs. Note that we could (and should) do without this
- # for all libraries except the RTS; all we need to do is to pass the
- # correct HSfoo_dyn.dylib files to the link command.
- # This feature requires Mac OS X 10.3 or later; there is a similar feature,
- # -flat_namespace -undefined suppress, which works on earlier versions,
- # but it has other disadvantages.
- # -single_module
- # Build the dynamic library as a single "module", i.e. no dynamic binding
- # nonsense when referring to symbols from within the library. The NCG
- # assumes that this option is specified (on i386, at least).
- # -Wl,-macosx_version_min -Wl,10.3
- # Tell the linker its safe to assume that the library will run on 10.3 or
- # later, so that it will not complain about the use of the option
- # -undefined dynamic_lookup above.
- # -install_name
- # Causes the dynamic linker to ignore the DYLD_LIBRARY_PATH when loading
- # this lib and instead look for it at its absolute path.
- # When installing the .dylibs (see target.mk), we'll change that path to
- # point to the place they are installed. Therefore, we won't have to set
- # up DYLD_LIBRARY_PATH specifically for ghc.
