From ec873a4c551e2851adbafa27c89872255a891bf7 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Tue, 17 Sep 2024 23:16:38 +0900 Subject: [PATCH] kbuild: refactor the check for missing config files This commit refactors the check for missing configuration files, making it easier to add more files to the list. The format of the error message has been slightly changed, as follows: [Before] ERROR: Kernel configuration is invalid. include/generated/autoconf.h or include/config/auto.conf are missing. Run 'make oldconfig && make prepare' on kernel src to fix it. [After] *** *** ERROR: Kernel configuration is invalid. The following files are missing: *** - include/generated/autoconf.h *** - include/config/auto.conf *** Run "make oldconfig && make prepare" on kernel source to fix it. *** Signed-off-by: Masahiro Yamada Reviewed-by: Nicolas Schier Tested-by: Miguel Ojeda --- Makefile | 21 +++++++++++++-------- 1 file changed, 13 insertions(+), 8 deletions(-) diff --git a/Makefile b/Makefile index b8efbfe9da94..096b1e6cd965 100644 --- a/Makefile +++ b/Makefile @@ -781,17 +781,22 @@ $(KCONFIG_CONFIG): else # !may-sync-config # External modules and some install targets need include/generated/autoconf.h # and include/config/auto.conf but do not care if they are up-to-date. -# Use auto.conf to trigger the test +# Use auto.conf to show the error message + +checked-configs := include/generated/autoconf.h include/config/auto.conf +missing-configs := $(filter-out $(wildcard $(checked-configs)), $(checked-configs)) + +ifdef missing-configs PHONY += include/config/auto.conf include/config/auto.conf: - @test -e include/generated/autoconf.h -a -e $@ || ( \ - echo >&2; \ - echo >&2 " ERROR: Kernel configuration is invalid."; \ - echo >&2 " include/generated/autoconf.h or $@ are missing.";\ - echo >&2 " Run 'make oldconfig && make prepare' on kernel src to fix it."; \ - echo >&2 ; \ - /bin/false) + @echo >&2 '***' + @echo >&2 '*** ERROR: Kernel configuration is invalid.
