I would like to fully understand Tensorflow mechanisms. To complete the task, I would like to build a debug library of Tensorflow 2.4, write a program using Tensorflow’s C++ API, link my object files to the Tensorflow debug library and debug the program using gdb/cuda-gdb. Can I get specific steps of building the debug library that can be used to fulfill my purpose?

I just viewed the discussion, and navigated to the following document: tensorflow/CONTRIBUTING.md at master · tensorflow/tensorflow · GitHub . In the document, it is pointed out that " the --config=dbg option is not officially supported".
I used the following command to build the source code of v2.4: “bazel build --config=cuda --config=dbg //tensorflow/tools/pip_package:build_pip_package”, and I got an error message:
ERROR: /tensorflow/tensorflow/BUILD:724:1: Linking of rule ‘//tensorflow:libtensorflow_framework.so.2.4.4’ failed (Exit 1)

bazel build --config=dbg --config=… cuda --cxxopt="-D_GLIBCXX_USE_CXX11_ABI=0" //tensorflow/tools/pip_package:build_pip_package
(for SM 7.0 only)
The build dies at link time with:

Adding -mcmodel=large makes no difference, as the overflow is in a debug section.
I tried -gdwarf64 which is not supported by gcc
