Hi folks, Currently our build environment uses parallel make (-j jobs option) on all our unixes using gnu tools. We use an older version of gnu tools on our windows boxes. The older make on the windows box does not do parallel make (or at least correctly). I want to upgrade to the latest cygwin to see if parallel make works, but this will require significant changes to our build engine, so I would like to confirm a few things if possible.
1. Does the -j jobs option work well on windows. (part b: does it work with the MSVC (6/7) compiler (which probably doesn't make a difference anyway)? 2. Has anyone done this in a very large project, and if so, do you have any performance gain stats (which, I acknowledge, is tied to processor-intensive makes and how many processors the machine has). I realize that dos does not allow for threading so I don't know if this is a cmd.exe-related issue or not (since cmd.exe is the parent shell, I don't know if this affects the behavior). thanks in advance -- -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
