Hello Tuomas,
the build dependencies for *.efi files are described in
./scripts/Makefile.lib:
EFI_LDS_PATH = $(srctree)/arch/$(ARCH)/lib/$(EFI_LDS)
cmd_efi_ld = $(LD) -nostdlib -znocombreloc -T $(EFI_LDS_PATH) -shared \
-Bsymbolic $^ -o $@
$(obj)/%_efi.so: $(obj)/%.o arch/$(ARCH)/lib/$(EFI_CRT0) \
arch/$(ARCH)/lib/$(EFI_RELOC)
$(call cmd,efi_ld)
$(obj)/%.efi: $(obj)/%_efi.so
$(call cmd,efi_objcopy)
The target is selected in lib/efi_loader/Makefile:
ifneq ($(CONFIG_CMD_BOOTEFI_HELLO_COMPILE),)
always += helloworld.efi
endif
obj-$(CONFIG_CMD_BOOTEFI_HELLO) += helloworld_efi.o
obj-y += efi_image_loader.o efi_boottime.o efi_runtim
Does the problem ever occur if you run mrproper beforehand?
To allow analyzing your problem, please, run make with parameter V=1,
provide the command line you used, the value of $CROSS_COMPILE, the
.config file, and the complete output of make.
Further provide the output of
find . -exec ls {} -la --time-style=full-iso \;
Best regards
Heinrich
