Hi @Biswa96, thank you for opening the issue. We don't actively test/support ninja, and I believe that's the cause of the first error (it's something I want but have not gotten to yet - patches welcome if this is important for your use-case). Without ninja, it looks like we have some build issues in GCC 11 and 12 due to new unused variable warnings in sub-projects which un-conditionally enable -Werror (aws-sdk-cpp). I was not able to avoid this even with exporting CXXFLAGS=-Wno-werror but we will take a look and see what else is possible to get the subproject to build.

The build errors should all be fixed here. I've put a fix for the ninja build in #3997. Please comment if needed and we will be happy to reopen.
