TensorFlow Python3.7环境下的源码编译(三)编译

这里要为仅支持 CPU 的 TensorFlow 构建一个 pip 软件包，需要调用以下命令：

$ bazel build --cxxopt="-D_GLIBCXX_USE_CXX11_ABI=0" --config=opt --verbose_failures //tensorflow/tools/pip_package:build_pip_package

 

大概编译15分钟后，输出错误信息如下：

这个错误我估计是编译器与代码兼容的问题，查找了半天暂时没找到解决办法，所以就暂时搁置了TensorFlow主分支代码在Python3.7环境下的代码编译，过一段时间再试试。
