After spending quite sometime on a related issue, I was able to get vw running on CentOS 7 Docker. Here are the steps I took:

Before beginning, if you've already installed CentOS's gcc-c++ package, uninstall it.

  1. Install newer developer toolset with a newer g++:

    yum -y install centos-release-scl 
yum -y install  devtoolset-6
/usr/bin/scl enable devtoolset-6 true

  2. Install Boost library and related libraries:

    yum -y install boost-devel.x86_64 libboost-all-dev \ 
       libboost-program-options-dev

  3. Install JDK if missing:

    yum -y java-1.7.0-openjdk java-1.7.0-openjdk-deve

  4. Link newer g++ to path normally occupied by 'gcc-c++':

    ln -s /opt/rh/devtoolset-6/root/usr/bin/g++ /usr/bin/g++

  5. Git clone and build:

    git clone https://github.com/JohnLangford/vowpal_wabbit.git
cd vowpa_wabbit
./autogen.sh
./configure
make
make install

  6. Now you can use vw binary to access vowpal_wabbit via its terminal interface. You may want to add export PATH=/usr/local/bin:$PATH to be able to use vw from overall.

The default compiler in CentOS 7 is gcc 4.8 that still has no full C++11 support including <codecvt> header, so you need to install and use a newer gcc version.

But if for some reason you can't, the good news is that <codecvt> is required by one of the auxiliary libraries that you probably don't need.

In this case you can just go ahead and build only the VW binary:

cd vowpalwabbit
make vw
