The EOSIO Contract Development Toolkit, CDT for short, is a collection of tools related to contract compilation. Subsequent tutorials use the CDT primarily for compiling contracts and generating ABIs.
Starting from 1.3.x, CDT supports Mac OS X brew, Linux Debian and RPM packages. The easiest option to install would be using one of these package systems. Pick one installation method only. [[warning]] | If you have versions of eosio.cdt prior to 1.3.0 installed on your system, please uninstall before proceeding
brew tap eosio/eosio.cdtbrew install eosio.cdt
brew remove eosio.cdt

The location where
eosio.cdt is cloned is not that important because you will be installing
eosio.cdt as a local binary in later steps. For now, you can clone
eosio.cdt to your "contracts" directory previously created, or really anywhere else on your local system you see fit.
Clone version 1.6.3 of the
git clone --recursive https://github.com/eosio/eosio.cdt --branch v1.6.3 --single-branchcd eosio.cdt
It may take up to 30 minutes to clone the repository
[[success | Virtual machine environment]] | In case you are using a virtual machine. It should be configured with at least 2 CPUs (does not have to be two physical ones) and 8G of memory to avoid compilation errors
The above command needs to be ran with
eosio.cdt's various binaries will be installed locally. You will be asked for your computer's account password.
eosio.cdt will make the compiled binary global so it can be accessable anywhere. For this tutorial, it is strongly suggested that you do not skip the install step for eosio.cdt, failing to install will make it more difficult to follow this and other tutorials, and make usage in general more difficult.
