# Need to update Travis's really old gcc for use with cpp14
# https://stackoverflow.com/questions/39728709/using-an-alternate-compiler-for-travis-ci-r-project-builds
# 1) Use g++-6 so we definitely have C++14 as the default
# 2) A Makevars is used to build all of the dependencies and my package with
#    gcc-6 and g++-6.
# 3) We remove the "request" for CXX14 in src/Makevars and let R just find
#    the default, which is now g++-6 (bc of step 2) which uses cpp14 by default.
#    Unfortunately this is required.

# base64 resolves to (yes with a new line for it to work):
# VER=-6
# CC=gcc$(VER)
# CXX=g++$(VER)
#
