Building ARM NN via Docker approach with specific GLIBC , GLIBCXX versions ... about armnn

[tracyn-arm]

Hi. Not sure if I fully understand your question but the common.sh script of build-tool forces the Arm NN aarch64 compiler:
AARCH64_COMPILER_FLAGS+="CC=/usr/bin/aarch64-linux-gnu-gcc CXX=/usr/bin/aarch64-linux-gnu-g++ "
Possibly the source of your symbol mismatch if multiple compilers end up being used. Thanks.

The build-tool builds for Ubuntu 20.04... I would say if you're going to be building and deploying to something older than that, or not similar to Ubuntu, you'll either need to modify the build-tool scripts or build directly using cmake.

Thanks for the quick replies.
I think my case is of "building and deploying to something older than, or not similar to, Ubuntu 20.04".
From what I now understand, I probably have to edit the shell scripts at build-tool/scripts/ properly (or use them as a guide) thus to build the recent ARM NN with the target's cross-compilation tools.
Thanks.
