If you have a ~/opt directory full of folders like boost, delete that before commencing the following (rather get everything fresh)

cd ~
git clone https://github.com/EOSIO/eos.git
cd ~/eos
git submodule update --init --recursive
./eosio_build.sh

To make the executable programs available (such as eosiocpp) run the following commands

tpmccallum

tim.cpp:15:64: error: no matching conversion for functional-style cast from 'uint64_t' (aka 'unsigned long long') to 'eosio::name'
       eosio::print( "Hello World: ", eosio::name(code), "->", eosio::name(action), "\n" );
