Syntaxnet on CentOS 6.6

[kskp]

Hi All,

I am trying to run syntaxnet on CentOS 6.6 but I am not able to. I have looked up other issues and tried everything I can but I can't get it running. I did the following till now:

1. Install python 2.7 by installing Anaconda. Path: /home/sree/anaconda2/bin/python

2. Installed gcc 4.9.1 using the instructions:

      a. wget http://linuxsoft.cern.ch/cern/scl/slc6-scl.repo
      b. yum -y --nogpgcheck install devtoolset-3-gcc devtoolset-3-gcc-c++
      c. scl enable devtoolset-3 bash
   

my gcc is at: /opt/rh/devtoolset-3/root/usr/bin/gcc

1. Install bazel:

     a. git clone https://github.com/bazelbuild/bazel.git && cd bazel
     b. git checkout tags/0.2.2b
     c. ./compile.sh
   

Bazel builds successfully and I have the binary at: /home/sree/bazel/output/bazel

When I do bazel version from /home/sree, i get: bash: /home/sree/bin/bazel: No such file or directory

So I did: mv /home/sree/bazel/output/bazel /home/sree/bin/bazel

1. Install tensorflow:

     a. git clone --recursive https://github.com/tensorflow/models.git
     b. cd models/syntaxnet/tensorflow
     c. ./configure
     d. cd ..
     e. bazel test syntaxnet/... util/utf8/...
   

After a lot of warnings and notes, i get:

ERROR: /home/sree/.cache/bazel/_bazel_sree/099a0ac170d26d787b0f9e5af193deee/external/protobuf/BUILD:331:1: Linking of rule '@protobuf//:protoc' failed: gcc failed: error executing command /opt/rh/devtoolset-3/root/usr/bin/gcc -o bazel-out/host/bin/external/protobuf/protoc -no-canonical-prefixes -B/opt/rh/devtoolset-3/root/usr/bin -B/usr/bin -pass-exit-codes '-Wl,--build-id=md5' ...

Can someone help me with what went wrong? I did not change any CROSSTOOL files for bazel or tensorflow. Should I change it to my default gcc path?

EDIT: Even if I changed the gcc paths in tensorflow/third_party/gpus/cosstool/CROSSTOOL and tensorflow/third_party/gpus/cosstool/clang/bin/crosstool_wrapper_driver_is_not_gcc file, I am getting the same error. I think it has something to do with the linker. Can someone give ne some pointers?

CentOS 7 and above are supported, can you try those instead?

@concretevitamin I tried and its working on CentOS 7. But I want to make it run on CentOS 6 cluster at my work. Upgrading the entire cluster to Centos 7 is a pain.
