Hi,

I want to build qemu-x86 as an 32-bit EFI payload.

What I have done is below:

step 1: make qemu-x86_defconfig

step 2: make menuconfig Library routines ---> [*] Support running U-Boot from EFI (X) Support running as an EFI payload (X) Produce a stub for running with 32-bit EFI

step 3: make

But finally, it fails:

lib/efi/efi_stub.o: In function `efi_main': /opt/u-boot-2016.07/obj/../lib/efi/efi_stub.c:357: undefined reference to `_binary_u_boot_dtb_bin_start' /opt/u-boot-2016.07/obj/../lib/efi/efi_stub.c:357: undefined reference to `_binary_u_boot_dtb_bin_end' /opt/u-boot-2016.07/Makefile:1117: recipe for target 'u-boot-payload' failed make[1]: *** [u-boot-payload] Error 1 make[1]: Leaving directory '/opt/u-boot-2016.07/obj' Makefile:150: recipe for target 'sub-make' failed make: *** [sub-make] Error 2

Can anybody tell me what mistakes I made?

Best Regards! Phenix
