It's not quite there because it doesn't seem to provide a way to pass down the current action (all/clean/install/etc) to the sub-Make. Any ideas how we could do that? Another example of the usefulness of phony targets is in conjunction with recursive invocations of `make'. In this case the makefile will often contain a variable which lists a number of subdirectories to be built. One way to handle this is with one rule whose command is a shell loop over the subdirectories, like this: SUBDIRS = foo bar baz subdirs: for dir in $(SUBDIRS); do \ $(MAKE) -C $$dir; \ done There are a few of problems with this method, however. First, any error detected in a submake is not noted by this rule, so it will continue to build the rest of the directories even when one fails. This can be overcome by adding shell commands to note the error and exit, but then it will do so even if `make' is invoked with the `-k' option, which is unfortunate. Second, and perhaps more importantly, you cannot take advantage of the parallel build capabilities of make using this method, since there is only one rule. By declaring the subdirectories as phony targets (you must do this as the subdirectory obviously always exists; otherwise it won't be built) you can remove these problems: SUBDIRS = foo bar baz .PHONY: subdirs $(SUBDIRS) subdirs: $(SUBDIRS) $(SUBDIRS): $(MAKE) -C $@ foo: baz Here we've also declared that the `foo' subdirectory cannot be built until after the `baz' subdirectory is complete; this kind of relationship declaration is particularly important when attempting parallel builds. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 7: don't forget to increase your free space map settings
