You can already completely control the order in which targets are invoked, even when using -j. At all times, make will try to build prerequisites starting with the first one in the prerequisite list, and continuing in order to the last one in the list. Invoking a parallel make does not change this algorithm, the ONLY thing it does is control how many jobs can be "in flight" at the same time. So, if you list your prerequisites in order with the longest ones first and the shortest ones last, then you will get the distribution you want. _______________________________________________ Bug-make mailing list Bug-make@gnu.org http://lists.gnu.org/mailman/listinfo/bug-make
