[Interest] How to build Qt using multiple CPU's on Mac?
Hi Everybody, On windows when I run nmake after configure, it uses all of my CPU's and is finished in under 2 hours. On mac OSX Lion with XCode 4.3.2, when I run make after configure, it only uses 1 CPU. My google fu is not working and I can't find the parameter for make to get it to use more CPU's. (It seems the problems forcing Qt compile to target OSX 10.6 have come back in 4.8.3, hence my need to build Qt a few times already). Thanks! Tony. ___ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest

Read man make for more details. -- Regards, Konstantin ___ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest

(Objviously adjust the 8 to whatever number of cores you have).
