Any ideas? Works for me, GNU Make version 3.79.1 building 2.6.7 on ia64. make -j8 modules gives a pstree of bash(2475)---make(29483)-+-make(29806)---make(30111)---make(30112)---sh(30113)---gcc(30114)-+-as(30116) | `-cc1(30115) `-make(29857)-+-make(29938)---sh(30153)---gcc(30154)-+-as(30156) | `-cc1(30155) |-make(30103)-+-sh(30104)---gcc(30105)-+-as(30107) | | `-cc1(30106) | `-sh(30146)---gcc(30147)-+-as(30149) | `-cc1(30148) `-make(30130)---sh(30131)---gcc(30132)-+-as(30134) `-cc1(30133) Not the full blown 8 way that I asked for, but that is an artifact of using recursive make instead of a single top level Makefile with all the dependencies. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
