From: Wolfgang Denk Date: Tue, 16 Dec 2008 13:41:02 +0000 (+0100) Subject: Makefile: fix dependency problem with parallel builds X-Git-Tag: v2009.01-rc1~3^2~3 X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=4a0f7538c5c0805fd9a791967bbabacc41deadd9;p=oweals%2Fu-boot.git Makefile: fix dependency problem with parallel builds Parallel builds (using "make -jN") would occasionally fail with error messages like include/autoconf.mk:212: *** missing separator. Stop. Line numbers and affected boards were changing. Obviously some Makefiles included autoconf.mk while it was still being written to. As a fix, we now write to a temporary file first and then rename it, so that it is really ready to use as soon as it appears.
