C++ example build error on Windows 10 with Tensorflow 1.12

System information

• OS Platform and Distribution Windows 10:
• TensorFlow installed from source:
• TensorFlow version: 1.12
• Python version: 3.6
• Installed using conda:
• Bazel version (if compiling from source): 0.20.0
• GCC/Compiler version (if compiling from source): Visual Studio 2015 tools
• CUDA/cuDNN version: without GPU
• GPU model and memory: without GPU

I cloned the Tensorflow Git repository and got the latest version from the master branch (commit [fe84b75] from Thursday, December 20, 2018 7:37:28 AM. I installed Bazel and I tried to compile the C++ example provided on the web site https://www.tensorflow.org/guide/extend/cc following the instructions. The required libraries from Tensorflow were compiled successfully but the example.cpp has a link error:

Thank you for help!

Can the current version of the Tensorflow C++ API work under Windows?

[matt-har-vey]

For myself, for now, I am content with just not linking the Unicode ops as a workaround.

https://gist.github.com/matth79/224962f167f01cd41ba21039eab51fbc

The correct solution is more along these lines:

#23655

[georgescortaru]

Thanks,
The solution from https://gist.github.com/matth79/224962f167f01cd41ba21039eab51fbc worked

[ymodak]

Closing this issue since its resolved. Feel free to reopen if have any further problems. Thanks!

I solved the problem by compiling icu4c,adding the path of lib64.

@gmt710 hi,can you teach me how to build tf on vs?

[gmt710]

@jesen8 hello,I wrote the installation instructions.May you follow this:windows+bazel+tensorflow-v1.12.0(GPU).

[jesen8]

thanks!,can you give me your wchart id?
