From: Thomas Weißschuh Date: Wed, 22 Apr 2026 15:10:27 +0000 (+0200) Subject: kbuild: Never respect CONFIG_WERROR / W=e to fixdep X-Git-Tag: v7.1-rc1~3^2 X-Git-Url: http://git.ipfire.org/gitweb/?a=commitdiff_plain;h=75f7c47ccd78c947cf1b6ddb18ea453ff0555716;p=thirdparty%2Fkernel%2Flinux.git kbuild: Never respect CONFIG_WERROR / W=e to fixdep The fixdep hostprog may be built multiple times during a single build. Once during the configuration phase and later during the regular phase. As only the regular build phase respects CONFIG_WERROR / W=e, the compiler flags might change between the phases, leading to rebuilds. Example, the rebuilds will happen twice on each invocation of the build: $ make allyesconfig prepare make[1]: Entering directory '/tmp/deleteme' HOSTCC scripts/basic/fixdep # # No change to .config # HOSTCC scripts/basic/fixdep DESCEND objtool INSTALL libsubcmd_headers make[1]: Leaving directory '/tmp/deleteme' Fix the compilation flags used for scripts/basic/ before scripts/Makefile.warn is evaluated to stop CONFIG_WERROR / W=e influencing the fixdep build to avoid the spurious rebuilds.
