Actually https://github.com/google/brotli/pull/893 this PR just fixed the GCC 11 build issue. It was merged at https://github.com/google/brotli/commit/0a3944c8c99b8d10cc4325f721b7c273d2b41f7b. Both of Pedro's patch and Ross's patch include that fix.

I think the difference between the Pedro's patch and Ross's patch is that besides of brotli version, Ross's patch don't have the changes in MdeModulePkg/Library/BrotliCustomDecompressLib/BrotliCustomDecompressLib.inf, that is

+  brotli/c/common/constants.c
+  brotli/c/common/context.c
   brotli/c/common/dictionary.c
+  brotli/c/common/shared_dictionary.c

Are these added c files necessary?

Can we use Ross's patch to fix GCC11 build issue?

Thanks,
Bob

Subject: 回复: [edk2-devel] [PATCH] BaseTools/Brotli: update to latest brotli submodule

Ross:
  I know the reason. Your patch is to update brotli version to the latest one e83c7b8e8fb8b696a1df6866bc46cbb76d7e0348, but previos Pedro's patch updates brotli version to one early version 4ec67035c0d97c270c1c73038cc66fc5fcdfc120. So, your PR can pass, but my PR fail.

Pedro:
  Can you update your patch to reference the latest brotli version e83c7b8e8fb8b696a1df6866bc46cbb76d7e0348?

Thanks
