From af5dc83da448ac6f911741d1a51ce315cb052057 Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Thu, 29 Jul 2010 15:40:28 +0200 Subject: linux: more mistake detection Just as we do for U-Boot, error out in the Linux kernel makefile when the defconfig name or the configuration file path are not correct. What prompted me to implement this was a report on IRC from an user using BR 2010.05 and not understand why the kernel build process was failing. It was because he just forgot to set the path of the configuration file. Of course, it doesn't catch all mistakes (like pointing to a non-existing defconfig or to a non-existing configuration file), but it at least catches basic mistakes.
