Timothy:
Thanks for your report. This is a real issue in Brotli decompress library. Which tool chain has been verified? GCC5 or VS2019 or Both?
Thanks

主题: Re: [edk2-devel] [PATCH V2] MdeModulePkg/Decompress: Add missing source file to Brotli library
[AMD Official Use Only - General]
This patch tried to fix following build failure when linking the Brotli decompress lib.
Steps to replicate the issue:
1 - Attach a NULL lib to DxeIpl.inf in any project's .DSC, say OvmfPkgX64.dsc
MdeModulePkg/Core/DxeIplPeim/DxeIpl.inf {
<LibraryClasses>
NULL|MdeModulePkg/Library/BrotliCustomDecompressLib/BrotliCustomDecompressLib.inf
}
2 - Follow the EDKII'2 package build steps to build that project. Build.py would compliains with following errors.

Hi Abner,
What was the failure before this change?
This looks like something that would always break the build of source files were missing.
Mike
