Is there a way to do it from within the Makefile (either > globally, or for specific targets)? It should work to add: MAKEFLAGS += -L into your makefile. You can't do it just for certain targets though... well, I guess you could replace those recipes with some kind of recursive make invocation that added the -L option for just those targets. ___ Help-make mailing list Help-make@gnu.org https://lists.gnu.org/mailman/listinfo/help-make

See: -L, --check-symlink-times Use the latest mtime between symlinks and target. From the manual: On systems that support symbolic links, this option causes make to consider the timestamps on any symbolic links in addition to the timestamp on the file referenced by those links. When this option is provided, the most recent timestamp among the file and the symbolic links is taken as the modification time for this target file. Supported in GNU make 3.81 and above.
