tensorflow/core/kernels/split_op.cc:159:26: error: non-constant-expression cannot be narrowed from type 'int64' (aka 'long long') to 'int' in initializer list [-Wc++11-narrowing]

Building tensorflow android error:

• os: ubuntu16.04
• tensorflow: 1.0.1

Before error comes, I followed the tips in android README

 bazel build -c opt //tensorflow/contrib/android:libtensorflow_inference.so \
   --crosstool_top=//external:android/crosstool \
   --host_crosstool_top=@bazel_tools//tools/cpp:toolchain \
   --cpu=armeabi-v7a

then I just got these error:

ERROR: /media/work/CodeSpace/AISpace/tensorflow/tensorflow/core/kernels/BUILD:3944:1: C++ compilation of rule '//tensorflow/core/kernels:android_tensorflow_kernels' failed: clang failed: error executing command external/androidndk/ndk/toolchains/llvm/prebuilt/linux-x86_64/bin/clang -gcc-toolchain external/androidndk/ndk/toolchains/arm-linux-androideabi-4.9/prebuilt/linux-x86_64 -fpic -ffunction-sections ...

I installed android sdk and ndk via android-studio, and here is my settings in WORKSPACE:

android_sdk_repository(
    name = "androidsdk",
    api_level = 23,
    # Ensure that you have the build_tools_version below installed in the
    # SDK manager as it updates periodically.
    build_tools_version = "25.0.2",
    # Replace with path to Android SDK on your system
    path = "/media/work/android/android-sdk",
)
#
# Android NDK r12b is recommended (higher may cause issues with Bazel)
android_ndk_repository(
    name="androidndk",
    path="/media/work/android/android-sdk/ndk-bundle",
    # This needs to be 14 or higher to compile TensorFlow. 
    # Note that the NDK version is not the API level.
    api_level=14)

Anybody occurred this problem too? I don't know what happed.

[andrewharp]

Make sure you're building with NDK r12b, as other versions are known to cause issues with Bazel.

Try building with bazel build --copt=-Wno-c++11-narrowing to disable this error. NDK13 switched from GCC to Clang, which has this check enabled by default.
