I am trying to build Tensorflowlite using the gcc cross compiler setup during the SDK installation, aarch64-agl-linux-gcc. I built the AGL demo for Raspberry Pi4 and installed it on my rpi. I install the sdk, source the environment script and try "bazel build --config=elinux_aarch64 --cxxopt=--std=c++11 //tensorflow/lite:libtensorflowlite.so --verbose_failures". Has anyone been able to build tensorflow that can run on AGL? I have scoured the internet but cant find anything and my experience with cross compiling in general is limited. Any help would be greatly appreciated!

AGL SDK Version 10.90 (latest as of a few weeks ago) and 9.0.3 so far
TF 2.3
Bazel 3.1.0
Docker Ubuntu 18.04 (setup with all TF dependencies)
aarch64-agl-linux-gcc 9.3
Steps to reproduce:
./poky-agl-glibc-x86_64-agl-demo-platform-crosssdk-aarch64-raspberrypi4-64-toolchain-10.90.0+snapshot.sh
. /opt/agl-sdk/10.90.0+snapshot-aarch64/environment-setup-aarch64-agl-linux
./configure (keep all default values in configure script)

Lastly please note that I get the same error but in different places when I run this build. Sometimes as above it cant find <function>, other times it cant find <map> and others it cant find <assert>
