Re: Make recursion does not appear working in VMS

As far as I know, --jobs is not implemented for VMS, unfortunately I can't point to an obvious line in the sources. It seems to be hidden in #if[n]def VMS in job.c and vmsjobs.c. Silently explicitly or implicitly reseting jobs to 1 isn't good. To look at this, can you post or send (one of) the modified makefiles for VMS? ___ Bug-make mailing list Bug-make@gnu.org https://lists.gnu.org/mailman/listinfo/bug-make

Sorry for long lines, only a seconds before I have to run. recurse line is wrapped in the e-mail client. 1.inc and 2.inc lines are wrapped in the e-mail client. This is one of the files that fails for recursion. I will have to send one that shows the parallelism failures later.
