Hi Haojian,

Normally this is caused by large structure variable copy operation, and compiler will change the code to memcpy. As there is no such function in your build, it will complain "undefined reference".

There are two ways to fix this:

1. Add compiler intrinsic library to your dsc file:

NULL|ArmPkg/Library/CompilerIntrinsicsLib/CompilerIntrinsicsLib.inf

It fixes the build issue. Thanks a lot.

Best Regards Haojian

2. Find the code which does structure copy and modify it with explicit

EDK2 CopyMem function.

Please have a try.

Hi all,

Do you meet this issue when build edk2? If I just build edk2 with DEBUG mode, it's fine. If I build edk2 with RELEASE mode, I'll meet the issue in below.
