Can you make sure you have a clean build folder when you are building on Debian?

Please also provide more detailed build steps for how to reproduce this exception.

thank you for your answer，i have a clean build again，Does S3client not support GCC12 version

[DmitriyMusatkin]

CPP SDK supports GCC12. Problems like the one you are observing are typically due to some mismatch with build artifacts, so clean rebuild of both sdk and your app typically helps. I dont have a Debian system handy, but AL2 with GCC works fine for this sample. If you are still getting this error after clean rebuild, we might need more info on exact platform you are observing the issue on. Ideally, a Dockerfile with exact OS and compiler versions that repro the issue would help.
