Hi, There are sometimes build failures that seem to be from race conditions, I've seen rump do it, maybe others too.
e.g. http://releng.netbsd.org/builds/netbsd-6/201610160430Z/ews4800mips.build.failed http://releng.netbsd.org/builds/netbsd-6-1/201610122020Z/evbmips-mips64el.build.failed It seems: {src/sys/rump} % grep '\-l' */Makefile* dev/Makefile.rumpdevcomp:RUMPDEVLDADD+=-lrumpdev_${var} fs/Makefile.rumpfscomp:RUMPFSLDADD+=-lrumpfs_${var} fs/Makefile.rumpfscomp:RUMPFSLDADD+=-lrumpvfs_${var}fs fs/Makefile.rumpfscomp:RUMPFSLDADD+=-lrumpvfs_${var} kern/Makefile.rumpkerncomp:RUMPKERNLDADD+=-lrumpkern_${var} net/Makefile.rumpnetcomp:RUMPNETLDADD+=-lrumpnet_${var} % ls librump ... rumpdev rumpkern rumpnet rumpvfs {src/sys/rump} % cat Makefile # $NetBSD: Makefile,v 1.7 2014/11/09 17:39:37 pooka Exp $ # SUBDIR= include SUBDIR+= librump SUBDIR+= dev fs kern net SUBDIR+= share Would adding SUBDIR+= .WAIT dev fs kern net be the right thing to resolve this dependency? thanks.
