Dwarf Error: Could not find abbrev number 38 / undefined reference to `memcpy'

Hello guys,

I`m trying to compile a simple UEFI Hello World using EDKII and a GCC cross compiler as described in this post:

The code works fine when I`m compiling for X64 platforms but I'm getting this Dwarf error when I'm compiling for AARCH64:

#include <Uefi.h>
#include <Library/UefiLib.h>

HelloWorld_EntryPoint (
  IN EFI_HANDLE        ImageHandle,
  Print(L"Hello World\n");
  // SystemTable->ConOut->OutputString(SystemTable->ConOut, L"Hello World");
  return EFI_SUCCESS;

The OutputString function works fine but all functions that somehow needs memcpy doesn't work.


/src/toolchain/gcc-arm-8.2-2019.01-x86_64-aarch64-elf/bin/../lib/gcc/aarch64-elf/8.2.1/../../../../aarch64-elf/bin/ld: Dwarf Error: Could not find abbrev number 38.
/tmp/cczBhuU4.ltrans0.ltrans.o: In function `UnicodeVSPrint.constprop.6':
<artificial>:(.text.UnicodeVSPrint.constprop.6+0x20): undefined reference to `memcpy'
collect2: error: ld returned 1 exit status

Does anyone know how could I fix it? I don't know if I'm missing something

Thank very much!!
