Whitepaper - Ethereum Classic With Cover

Ethereum Classic Documentation, Release 0.1
We use a common CMake build system to generate platform-specific build files, meaning that the workflow is
very similar whatever operating system you use:
• Install build tools and external packages (these are platform dependent)
• Clone the source code from the webthree-umbrella git repository
• Run CMake to generate a build file (makefile, Visual Studio solution, etc)
• Build it
Platform-specific instructions
Building for Linux NOTE - It may be possible to get the client working for Linux 32-bit, by disabling EVMJIT
and maybe other features too. We might accept pull-requests to add such support, but we will not put any of our
own development time into supporting Linux 32-bit builds.
Linux has a horror-show of distro-specific packaging system steps which are the first thing which we need to do
before we can start on Building from source. The sections below attempt to capture those steps. If you are using
as different distro and hit issues, please let us know.
Clone the repository
To clone the source code, execute the following command:
git clone --recursive https://github.com/bobsummerwill/cpp-ethereum.git
cd cpp-ethereum
git checkout merge_repos
git submodule update --init
Installing dependencies (the easy way!) For the “Homecoming” release (v1.3.0) in July 2016 we added a new
“one-button” script for installing external dependencies, which identifies your distro and installs the packages
which you need. This script is new and incomplete, but is a way easier experience than the manual steps described
in the next section of this document. Give it a go! It works for Ubuntu and macOS and a few other distros already.
If you try it, and it doesn’t work for you, please let us know and we will prioritize fixing your distro!:
./install_deps.sh
