# On macOS, binaries refer to dynamic library dependencies using
|
|
# either relative paths (e.g. "libicudata.dylib", searched relative to
|
|
# $DYLD_LIBRARY_PATH) or absolute paths
|
|
# (e.g. "/nix/store/.../lib/libicudata.dylib"). In Nix, the latter is
|
|
# preferred since it allows programs to just work. When linking
|
|
# against a library (e.g. "-licudata"), the linker uses the install
|
|
# name embedded in the dylib (which can be shown using "otool -D").
|
|
# Most packages create dylibs with absolute install names, but some do
|
|
# not. This setup hook fixes dylibs by setting their install names to
|
|
# their absolute path (using "install_name_tool -id"). It also
|
|
# rewrites references in other dylibs to absolute paths.
