Hi David yeah, SYNCSH_SERIALIZE is equal to what I do today using this construct: (flock -s 200; some-command $^ $@) 200>/var/lock/some-lockfile It satisfies the single-thread requirement, but in massively parallel runs, several of these often end up waiting for each other. It would be optimal if make knew not to submit more than 1 at a time, I was just wondering if I'd skipped a page in the manual :-) /Per Jessen, Zürich _______________________________________________ Help-make mailing list [email protected] https://lists.gnu.org/mailman/listinfo/help-make
