From: Arnout Vandecappelle Date: Sat, 28 Apr 2012 07:14:50 +0000 (+0000) Subject: config: make it possible to specify which config file to use for 'make defconfig' X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=33f454bbef77638a29ec24807e30740323e15b3e;p=buildroot.git config: make it possible to specify which config file to use for 'make defconfig' So that this works: % make defconfig BR2_DEFCONFIG=~/buildroot-defconfig Right now we have to do: % cp ~/buildroot-defconfig configs/buildroot_defconfig % make buildroot_defconfig That would dirty the buildroot tree and requires it to be writable.
