# FIRST PART
# build osx64 toolchain (stripped of man documentation)
# the toolchain produced is not self contained, it needs clang at runtime
#
# SECOND PART
# build gcc (no g++) centos6-x64 toolchain
# doc: https://crosstool-ng.github.io/docs/
# apt-get should be all dep to build toolchain
# sed and 1st echo are for convenience to get the toolchain in /tmp/x86_64-centos6-linux-gnu
# other echo are to enable build by root (crosstool-NG refuse to do that by default)
# the last 2 rm are just to save some time and space writing docker layers
#
# THIRD PART
# build fpm and creates a set of deb from gem
# ruby2.0 depends on ruby1.9.3 which is install as default ruby
# rm/ln are here to change that
# created deb depends on rubygem-json but json gem is not build
# so do by hand


# might wanna make sure osx cross and the other tarball as well as the packages ends up somewhere other than tmp
# might also wanna put them as their own layer to not have to unpack them every time?
