# This binary may be built for either desktop or Android.
# A typical Android build command will look like the following:
# bazel build -c opt tensorflow/core:android_tensorflow_lib \
# --crosstool_top=//external:android/crosstool \
# --cpu=armeabi-v7a \
# --host_crosstool_top=@bazel_tools//tools/cpp:toolchain
#
# NOTE: currently '-pthread' must be removed from the LINK_OPTS variable
# in @protobuf//:BUILD to sucessfully build for Android. This is temporary
# pending an update of the version of the protobuf library that Tensorflow
# uses.
