My suspicion is that this is a result of make's directory caching. The wildcard function reads through the directory cache to get the results of the wildcard match. That means that if make has cached the contents of the directory then you run a $(shell ...) function which modifies the directory "behind make's back" (basically outside of a rule with that file as a target), make will not notice the change. _______________________________________________ Help-make mailing list [email protected] https://lists.gnu.org/mailman/listinfo/help-make
