Failing to build tensorflow C++ API on raspberry pi model 3 b+

[ahilleary]

Describe the Issue

I am following this guide (https://gist.github.com/EKami/9869ae6347f68c592c5b5cd181a3b205) to install tensorflow on a raspberry pi for c++. I attempt to build the tensorflow library with this command:
bazel build -c opt --config=monolithic --local_resources 1024,1.0,1.0 --verbose_failures //tensorflow:libtensorflow_cc.so

Steps to Reproduce

Follow the guide above but skipping the portion where he says to replace:
native.new_http_archive(
name = "eigen_archive",
urls = [
"http://mirror.bazel.build/bitbucket.org/eigen/eigen/get/f3a22f35b044.tar.gz",
"https://bitbucket.org/eigen/eigen/get/f3a22f35b044.tar.gz",
],
sha256 = "ca7beac153d4059c02c8fc59816c82d54ea47fe58365e8aded4082ded0b820c4",
strip_prefix = "eigen-eigen-f3a22f35b044",
build_file = str(Label("//third_party:eigen.BUILD")),
)
as doing so caused me problems. I also used all of the newest versions of software the tutorial has you download

Hardware/Software Info

Please provide the following information about your Raspberry Pi setup:

• Raspberry Pi model: 3 B+
• Operating System used: Raspbian Stretch
• Version of Python used: 3.5.3
• SD card memory size: 32 GB
• Size of USB/other device used as swap (if building from source): 16 GB
• TensorFlow git commit hash (if building from source): I cloned the repository October 19 2018

+1. Same here When I tried to build tensorflow.so for C++ shared lib. I am getting same issues.
