.travis.yml

# This is the simple Travis configuration, which is intended for use
# on applications which do not require cross-platform and
# multiple-GHC-version support. For more information and other
# options, see:

# Copy these contents into the root directory of your Github project in a file
# named .travis.yml

# EAC: sudo seems to be requried to get a machine with enough memory to compile.
# see https://docs.travis-ci.com/user/ci-environment/
sudo: required

# Do not choose a language; we provide our own build tools.

# EAC: By default, TravisCI has gcc/g++-4.6.3, which is too old for lol-cpp.
# I tried explicitly using gcc-4.9, but couldn't install unix-2.7.0 with that
# (linking errors). Instead, I'm using "dist:trusty", which has a newer version
# of gcc (4.8.4) by default.
