Thanks for your report, I can reproduce the error on x86:
make ARCH=x86_64 olddefconfig make ARCH=x86_64 prepare
The build error is related with "ARCH=x86_64", there is no error without "ARCH=x86_64" when build locally on x86.
As described in Documentation/kbuild/makefiles.rst:
For example, you can pass in ARCH=i386, ARCH=x86_64, or ARCH=x86. For all of them, SRCARCH=x86 because arch/x86/ supports both i386 and x86_64.
we should use SRCARCH instead of ARCH to specify the directory, like this:
diff --git a/scripts/Makefile b/scripts/Makefile index 576cf64..e4cca53 100644 --- a/scripts/Makefile +++ b/scripts/Makefile @@ -31,9 +31,12 @@ HOSTLDLIBS_sign-file = $(shell $(HOSTPKG_CONFIG) --libs libcrypto 2> /dev/null |
ifdef CONFIG_UNWINDER_ORC ifeq ($(ARCH),x86_64) -ARCH := x86 +SRCARCH := x86 endif -HOSTCFLAGS_sorttable.o += -I$(srctree)/tools/arch/x86/include +ifeq ($(ARCH),loongarch) +SRCARCH := loongarch +endif +HOSTCFLAGS_sorttable.o += -I$(srctree)/tools/arch/$(SRCARCH)/include HOSTCFLAGS_sorttable.o += -DUNWINDER_ORC_ENABLED endif I will update the related code of this patch in the next version.
Thanks, Tiezhu
