# language: instructs travis what compilers && environment to set up in build matrix
language: cpp

# sudo: false instructs travis to build our project in a docker VM (faster)
# Can not yet install fglrx packages with 'false'
sudo: required # false
dist: trusty

# os: expands the build matrix to include multiple os's
# disable linux, as we get sporadic failures on building boost, needs investigation
os:
  - linux
  - osx

# compiler: expands the build matrix to include multiple compilers (per os)
compiler:
  - gcc
  - clang

addons:
  # apt: is disabled on osx builds
  # apt: needed by docker framework to install project dependencies without
