Install Golang, building Golang programs

Install Golang.md

Install Go with Homebrew (OS X)

    brew install go

Create directories for GOPATH:

    mkdir ~/go
    mkdir ~/go/src

Add to .bash_profile

    export GOROOT=/usr/local/opt/go/libexec
    export GOPATH=$HOME/go
    export PATH="$GOPATH/bin:$PATH"

Install Go on Linux

Download the latest distribution:

    curl -O https://storage.googleapis.com/golang/go1.10.linux-amd64.tar.gz

Unpack it to the /usr/local

    sudo tar -C /usr/local -xzf go1.10.linux-amd64.tar.gz

For Go to work properly, you need to set the following two environment variables:

Setup a go folder

    mkdir -p ~/go; echo "export GOPATH=$HOME/go" >> ~/.bashrc

Update your path

    echo "export PATH=$PATH:$HOME/go/bin:/usr/local/go/bin" >> ~/.bashrc

Read the environment variables into current session:

    source ~/.bashrc
