Hi @saicharanbhimaraju1 , can you give us more details on how to reproduce this issue? Additionally, could you tell me why the config is elinux_aarch64 and not as shown in the guide?

Hi @Rohanjames1997 I wanted to build tensorflowlite flex so file for arm64 target, so I used config elinux_aarch64 which is in .bazelrc file.
Steps to reproduce the issue:

1. Download tensorflow v2.15 source
2. cd tensorflow and execute bazel build -c opt --config=elinux_aarch64 tensorflow/lite/delegates/flex:tensorflowlite_flex

Just today morning I was able to build tensorflow flex so file arm64 target with tensorflow v2.9.1 with same steps along with that I took help from [https://github.com//issues/52018] .

Are you satisfied with the resolution of your issue?
