Building Tensorflow 1.4.0 from sources for C/C++ in Ubuntu 17.10

I am trying to build Tensorflow 1.4.0 from sources for C/C++ in 64-bit Ubuntu 17.10. I tried to follow the instructions in Tensorflow website and other website for C++ using Bazel and summarize them as follows:

cd tensorflow
./configure
(select N for all the options)
bazel build --config=opt --cxxopt="-D_GLIBCXX_USE_CXX11_ABI=0" --local_resources 2048,.5,1.0 //tensorflow:libtensorflow_cc.so //tensorflow:libtensorflow_framework.so //tensorflow/tools/pip_package:build_pip_package
bazel-bin/tensorflow/tools/pip_package/build_pip_package /tmp/tensorflow_pkg
sudo -H pip3 install /tmp/tensorflow_pkg/tensorflow-1.4.0rc1-cp36-cp36m-linux_x86_64.whl

When I tried to build a simple test program and include tensorflow/core/public/session.h in Eclipse (with the include path set to the tensorflow root folder downloaded from git), it complained several things:

  1. Missing Google's protobuf common.h in device_attributes.pb.h (I cannot use apt-get to install protobuf as it will complain version too old - lower than 3.0.0.4 check in device_attributes.pb.h). I downloaded the latest protobuf and follow the instructions to install it
  2. Missing Eigen3's Tensor file in tensor.h, where tensor.h includes Tensor file in [tensorflow directory]/third_party/eigen3/unsupported/Eigen/CXX11/Tensor, and [tensorflow directory]/third_party/eigen3/unsupported/Eigen/CXX11/Tensor includes the missing [/usr/include/eigen3/]unsupported/Eigen/CXX11/Tensor file provided by libeigen3-dev. I apt-get to install libeigen3-dev.
  3. After I installed libeigen3-dev, I added /usr/include/eigen3 to the Eclipse's include path as the Tensor file in tensorflow directory is unable to find the Tensor file in /usr/include (with extra eigen3 directory).
  4. Missing nsync_cv.h file in mutex.h. I added nsync folder in tensorflow directory to the include path.

In summary, I have added the following paths to the include path in Eclipse:

I added the library path [tensorflow directory]/bazel-bin/tensorflow with the following libraries:

I have also added -std=c++11 to the GCC C++ compiler and GCC C++ Linker in the Eclipse's project settings. In the end it encountered a linker error:

[tensorflow directory]/tensorflow/core/platform/default/logging.h:187: undefined reference to `tensorflow::internal::CheckOpMessageBuilder::NewString[abi::cxx11]()'

I have seen a thread discussing similar issue but I did set -D_GLIBCXX_USE_CXX11_ABI=0 and Ubuntu 17.10 is using gcc5 or above.

Please kindly suggest how to fix the linker error. Many thanks!

If you don't want to tinker with your environment too much there are two unofficial alternatives. One is to compile the C++ API with Floop's tensorflow_cc project and install on your system. The other possibility is to install one of the releases of my packaging project for C and C++ API of Tensorflow. Both projects use CMake (instead of Bazel) to support C++ compilation of your source files.

From Tensorflow point of view, the advantage of tensorflow_cc that you can build GPU support if you want while my project can only use CPU for inference.

Officially, you have to create your C++ project in tensorflow sourcetree, write BUILD file and compile it using bazel. Look at this.

I wrote a blog post: https://tuanphuc.github.io/standalone-tensorflow-cpp/ giving detailed instructions to make a standalone C++ Tensorflow with configuration: - Ubuntu 17.10 - gcc 7.2.0 - tensorflow 1.4.0 - Python 2 or 3 - cmake 3.9.6 - Eigen 3.3.4 - Protobuf (master branch) - Googletest (master branch) - bazel Hope it helps

Packaged TensorFlow C++ library for bazel-independent use

graph.pb.h missing
