Note above that # all the primary targets depend on the "content" target, _before_ # anything else. This ensures that the content gets rebuilt (if necessary) # before anything else happens. # # This may seem redundant, given that SOURCE_XML depends on CONTENT_SRC in # the rule above. However, this rule only works if we change one of the # actual content files. What if instead, we change a graphic associated # with one of the content files, without changing the content file itself? # In this case, make assumes that nothing needs to be done, because the # content file is older than the target, and this makefile knows nothing # about any dependencies that the content file might have (that's dealt # with by the makefile in the appropriate content directory). This is the # main downside of having independent makefiles. # # So, the slightly convoluted workaround using the empty "content" target # ensures that the content files will always be checked, regardless of # whether they've changed. If any of their prerequisites for a particular # content file change, then the content file itself will be touched, thus # activating the SOURCE_XML rule above. This process is particularly # important to ensure that associated graphics get rebuilt when they # change. # # All that aside, however, the _real_ trick is to ensure that this rule is # only executed once. If we do a "make", this rule would nominally get # executed four times (once for each of the targets that depend on # "content"). The first time through the rule, therefore, we create a # marker file called "content-checked". If this file exists, the rule # isn't executed. These marker files are cleaned up by a one-off find # command when the makefile is first run (see the include file # one-time-init.make). # # Note: using the wildcard function to test for the existence of the # marker file doesn't work when the makefile is run standalone, because # the function result is expanded at the time the makefile is _loaded_, # _before_ the one-time initialisation has a change to kick in and delete # the file. This has the rather bizarre side-effect of the makefile only # re-checking the content on every second run, and means that we can't use # make conditionals to control rule execution. The solution is to prefix # every command in the rule with "test ! -f" to check whether the marker # file exists. # # Ack!
