Ubuntu 14.04 LTS Build Guide

Ubuntu 14.04 has a recent enough GCC for building MeTA, but we’ll need to add a ppa for a more recent version of CMake.

Start by running the following commands to install the dependencies for MeTA.

# this might take a while
sudo apt-get update
sudo apt-get install software-properties-common

# add the ppa for cmake
sudo add-apt-repository ppa:george-edison55/cmake-3.x
sudo apt-get update

# install dependencies
sudo apt-get install cmake libicu-dev git

Once the dependencies are all installed, you should double check your versions by running the following commands.

g++ --version

should output

g++ (Ubuntu 4.8.2-19ubuntu1) 4.8.2
Copyright (C) 2013 Free Software Foundation, Inc.

and

cmake --version

should output

cmake version 3.1.1

CMake suite maintained and supported by Kitware (kitware.com/cmake).

Once the dependencies are all installed, you should be ready to build. Run the following commands to get started:

# clone the project
git clone https://github.com/meta-toolkit/meta.git cd meta/

# set up submodules
git submodule update --init --recursive

# set up a build directory
mkdir build
cd build
cp ../config.toml .

# configure and build the project
cmake ../ -DCMAKE_BUILD_TYPE=Release
make

You can now test the system by running the following command:

ctest --output-on-failure

If everything passes, congratulations! MeTA seems to be working on your system.
