runInjectRPaths :: Logger -> ToolSettings -> [FilePath] -> FilePath -> IO () Source #
On macOS we rely on the linkers -dead_strip_dylibs flag to remove unused
libraries from the dynamic library. We do this to reduce the number of load
commands that end up in the dylib, and has been limited to 32K (32768) since
macOS Sierra (10.14).
-dead_strip_dylibs does not dead strip -rpath entries, as such passing
-l and -rpath to the linker will result in the unnecessary libraries not
being included in the load commands, however the -rpath entries are all
forced to be included. This can lead to 100s of -rpath entries being
included when only a handful of libraries end up being truly linked.
Thus after building the library, we run a fixup phase where we inject the
-rpath for each found library (in the given library search paths) into the
dynamic library through -add_rpath.
