Native client deepspeech utils so undefined reference to symbol roundf glibc 2 2 5

I am trying to build the native_client binaries from source, as
documented in 'native_client/README.md'.

In the section 'Building', I am requested to run the following command
bazel build slash --config=monolithic -c opt slash --copt=-O3
slash --copt=-fvisibility=hidden //native_client:libdeepspeech.so
//native_client:deepspeech_utils //native_client:generate_trie

The target //native_client:deepspeech_utils gives the following error : slash
undefined reference to symbol 'roundf[ slash GLIBC_2.2.5]'

So I add '-lm' to 'linkopts' in 'native_client/BUILD', I then get : slash
undefined reference to slash `main'

So I add '-c' to 'linkopts' in 'native_client/BUILD', I then get : slash
output 'native_client/libdeepspeech_utils.so' was not created

How is it even supposed to be created, I don't know... However
libdeepspeech_utils.a is created, so it seems we might be building a
static library instead of a shared one ?

Why is this target using 'cc_library' and not 'tf_cc_shared_object' as
for 'libdeepspeech.so' ?

Why isn't named 'libdeepspeech_utils.so' with the .so extension ?

It seems that almost nobody ever used bazel except to build TensorFlow
and the documentation is very poor. So it is hard to find any help.

Can you share more details on exactly what you are doing ?

What kind of details do you need ?

I want to be able to modify the C++ source code, so I am trying to build
the existing code. I have cloned mozilla/tensorflow and simply followed
instructions in slash 'native_client/README.md'.

Both mozilla/tensorflow and mozilla/deepspeech are on the HEAD of their
master branch.

Which system are you building for? If you are using DeepSpeech/master,
you should be using tensorflow/r1.6.

I am building for linux 64 with CUDA. I have just switched to
tensorflow/r1.6 and seems to have the same issue.

I have also hit the following error (which has already been reported) :

> Illegal ambiguous match on configurable attribute 'deps' in
> [ slash jpeg]//:jpeg: slash
> [ slash jpeg]//:k8 slash
> [ slash jpeg]//:armeabi-v7a

So I have commented out the armeabi-v7a part.

It seems really spurious. Which distro are you targetting ? Which
version of bazel are you using ?

If you are building for CUDA then you lack --config=cuda as well ...
