No. C will never be run first, before B. If you enable parallel builds then B and C might be run at the same time (but B will still be started first, then C). In the first example, first B and C will be rebuilt then A will be rebuilt if either A doesn't exist, OR B or C are newer than A. In the second example, first B and C will be rebuilt then A will be rebuilt if A doesn't exist, period. Since B and C are related to A by build order ONLY, they are built first BUT they don't play a role in deciding if A should be rebuilt. _______________________________________________ Bug-make mailing list Bug-make@gnu.org https://lists.gnu.org/mailman/listinfo/bug-make
