Build
This document describes how to build the Second State DevChain.
Binary build
Binary builds of the Second State DevChain are limited to Ubuntu 16.04 and CentOS 7.
Ubuntu 16.04
First, let’s install and update necessary packages on a clean Ubuntu 16.04 install.
$ sudo apt update -y
$ sudo apt install -y curl wget git bison build-essential
Next, you must have GO language version 1.10+ installed. The easiest way to get GO 1.10 is through the GVM. Below are the commands.
$ bash < <(curl -s -S -L https://raw.githubusercontent.com/moovweb/gvm/master/binscripts/gvm-installer)
$ gvm install go1.10.3 -B
$ gvm use go1.10.3 --default
Now, pull the devchain source code from Github, and then build the binary executable for Ubuntu 16.04.
$ go get github.com/second-state/devchain
$ cd $GOPATH/src/github.com/second-state/devchain
$ make all
Once successful, the binary executable from the build is $GOPATH/bin/devchain.
$ which devchain
/home/ubuntu/.gvm/pkgsets/go1.10.3/global/bin/devchain
CentOS 7
TBD
Docker build
First, install Docker.
$ sudo apt install docker.io
$ sudo usermod -a -G docker $USER
Log out and then log back in. Clone the repository from Github to your build machine.
$ git clone https://github.com/second-state/devchain.git
$ cd devchain
Next, build a Docker image for the build environment.
$ docker build -t secondstate/devchain-build -f Dockerfile.build.ubuntu .
...
Successfully tagged secondstate/devchain-build:latest
Finally, you can build the Docker image of the node.
$ docker build -t secondstate/devchain .
...
Successfully tagged secondstate/devchain:latest
You can now see the Docker image you just built.
$ docker image ls
