DeepSpeech: libctc_decoder_with_kenlm.so can't find symbol

For support and discussions, please use our Discourse forums.

If you’ve found a bug, or have a feature request, then please create an issue with the following information:

• Have I written custom code (as opposed to running examples on an unmodified clone of the repository):
• OS Platform and Distribution (e.g., Linux Ubuntu 16.04): 16.04
• TensorFlow installed from (our builds, or upstream TensorFlow): (‘v1.5.0-17-gad8f785’, ‘1.5.0-warpctc0.1’)
• TensorFlow version (use command below):
• Python version: 2.7.3
• Bazel version (if compiling from source): 0.9
• GCC/Compiler version (if compiling from source): gcc (Ubuntu 5.4.0-6ubuntu1~16.04.9) 5.4.0 20160609
• CUDA/cuDNN version: 8.0/6
• GPU model and memory: 8G
• Exact command to reproduce:

Because tensorflow1.5 don’t support cuda8 and cudnn6, I built both tensorflow and native_client from source as follows:

1. get tensorflow r1.5 from mozilla’s fork: git clone https://github.com/mozilla/tensorflow.git git checkout r1.5
2. ./configure
3. build native_client
4. build tensorflow

But when I run python DeepSpeech.py, it print error messages:

tensorflow.python.framework.errors_impl.NotFoundError: native_client/libctc_decoder_with_kenlm.so: undefined symbol: _ZN10tensorflow11GetNodeAttrERKNS_9AttrSliceENS_11StringPieceEPNSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEE

So I check this so file: ldd native_client

ldd native_client/libctc_decoder_with_kenlm.so 
        linux-vdso.so.1 =>  (0x00007ffcd6b41000)

it seems libctc_decoder_with_kenlm.so need _ZN10tensorflow11GetNodeAttrERKNS_9AttrSliceENS_11StringPieceEPNSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEE But libtensorflow_framework.so do not have that.
