From 501ef81040baa2ee31de6dd9f75d619de0e4c9bc Mon Sep 17 00:00:00 2001 From: Daniel Golle Date: Sun, 7 Apr 2024 19:50:04 +0100 Subject: [PATCH] config: select KERNEL_WERROR if building with default GCC version At the moment we have to manually follow the default GCC version also in config/Config-kernel.in. This tends to be forgotten at GCC version bumps (just happened when switching from version 12 to 13). Instead, introduce a hidden Kconfig symbol which implies KERNEL_WERROR in toolchain/gcc/Config.in where it is visible for developers changing the default version. Also remove the explicit default on BUILDBOT to avoid a circular dependency and also because buildbots anyway implicitly always select the default GCC version.
