Installing go

MDL supports go1.10+.

For OSX

First you need to have homebrew installed, if you don't have it yet.

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

Then, let's install go's latest version.

brew install go

Lastly, let's install Mercurial and Bazaar

brew install mercurial bzr

For linux

We need to install linux dependencies on the correct distribution.

Ubuntu and Debian

sudo apt-get update && sudo apt-get upgrade -y
sudo apt-get install -y curl git mercurial make binutils gcc bzr bison libgmp3-dev screen gcc build-essential

Centos and Fedora

sudo yum update -y && sudo yum upgrade -y
sudo yum install -y git curl make gcc mercurial binutils bzr bison screen
if [[ "$(cat /etc/redhat-release | grep -o CentOS)" == "CentOS" ]]; then sudo yum install -y build-essential libgmp3-dev; else sudo yum groupinstall -y "Development Tools" "Development Libraries" && sudo yum install -y gmp; fi;

Archlinux

First update the system and ensure the dependancies are met

sudo pacman -Syy && sudo pacman -Syu
sudo pacman -S base-devel

Install the latest version of go on Archlinux with:

sudo pacman -S go

Install Go manually

Install Go

Let's go to home directory and declare go's version that you want to download.

cd ~
export GOV=1.11.1 # golang version

After that, let's download and uncompress golang source.

curl -sS https://storage.googleapis.com/golang/go$GOV.linux-amd64.tar.gz > go$GOV.linux-amd64.tar.gz
tar xvf go$GOV.linux-amd64.tar.gz
rm go$GOV.linux-amd64.tar.gz

lastly, let's install go.

sudo mv go /usr/local/go
sudo ln -s /usr/local/go/bin/go /usr/local/bin/go
sudo ln -s /usr/local/go/bin/godoc /usr/local/bin/godoc
sudo ln -s /usr/local/go/bin/gofmt /usr/local/bin/gofmt

Note: Find any golang source version at Go Website

Setup your GOPATH

The $GOPATH environment variable specifies the location of your workspace. It defaults to a directory named go inside your home directory, so $HOME/go on Unix.

Create your workspace directory with it's respective inner folders:

mkdir -p $HOME/go
mkdir -p $HOME/go/bin
mkdir -p $HOME/go/src
mkdir -p $HOME/go/pkg

Setup $GOPATH variable, add it to ~/.bashrc. After editing, run source ~/.bashrc or open a new tab.

export GOROOT=/usr/local/go
export GOPATH=$HOME/go
export GOBIN=$GOPATH/bin
export PATH=$PATH:$GOBIN

Test your Go installation

Create and run the hello.go application described here: https://golang.org/doc/install#testing to check if your Go installation is working.
