Current behavior?

I was trying to build the tensorflow.dll in Windows to use the C++ API in my code. After successfully building tensorflow.dll and trying to use it in the code, I had faced several missing symbols error while linking. But by adding TF_EXPORT I was able to remove most of it. But there was still one symbol that was missing, which is tensorflow::RunOptions::RunOptions(void).

As far as I observed this is from a dynamically generated config.pb.h from tensorflow/core/protobuf/config.proto. What I have tried is to apply TF_EXPORT to the generated config.pb.h file in relevant places. But as soon as I run the bazel build command for the target, The config.pb.h and the config.pb.cc files are regenerated, thus whatever changes I made for exporting those symbols invalid. And after the build I still get the same tensorflow::RunOptions::RunOptions(void) symbol missing error while linking.

My question is how can I specifically export symbols from dynamically generated stub files from proto files while building ?
I was surprised no one has faced this problem before.

Standalone code to reproduce the issue

Build tensorflow with the following command.

`bazelisk.exe build --config=opt --config=win_clang //tensorflow:tensorflow.dll //tensorflow:tensorflow_dll_import_lib //tensorflow:install_headers`

Use the resulting `tensorflow.dll` and `tensorflow.lib` to compile custom code in MSVC.


    std::string filename = std::filesystem::path(model).filename().string();
    filename.resize(filename.length() - 3);
    tensorflow::SavedModelBundle bundle;
    tensorflow::SessionOptions session_options;
    tensorflow::RunOptions run_options;
    run_options.Clear();
    tensorflow::Status status = tensorflow::LoadSavedModel(session_options, run_options, model, { }, & bundle);

@advnpzn,
Could you please provide the complete error log of the installation process which helps us to debug the issue in an effective way. Thank you!

Hi @tilakrayal

Could you please specify which logs do you want specifically?
I could provide you the bazel build log for tensorflow.dll and the error output I get while compiling/linking a sample program with that tensorflow.dll.

@advnpzn,
The logs which are available while trying to build the tensorflow on WIndows would be helpful for us to debug the issue and provide the resolution. Thank you!
