I am trying to build a model using tflite micro but it is not working. All the files I have added but linking is not working. Can anyone help in this?

After running these commands:
# 1. Clean previous object files
rm -rf build/*
# 2. Open build_files.txt and paste exactly what I wrote above
nano build_files.txt
# [Paste and Save]
# 3. Build again
./build.sh
# 4. Check symbols
./check_missing_symbols.sh
Otuput I am getting:

I am trying to build a model on ubuntu and I am able to build successfully but in the linking I am getting errors I have already tried every mehtod, but no solution.
