Getting started with Go language - documenting steps that I am doing to start with Go language


Installation
------------

Installing Go language from source, because version in Ubuntu repo is too old.

from stackoverflow : http://stackoverflow.com/questions/17480044/how-to-install-the-current-version-of-go-in-ubuntu
There is GVM to maintain different versions of Go (https://github.com/moovweb/gvm)
but someone is saying there are too many dependencies and I don't want to keep
fighting with it.

Official doc to install from source is the best way to go for now.
Following : http://golang.org/doc/install/source

Install C tools on Ubuntu 
sudo apt-get install gcc libc6-dev libc6-dev-i386
# libc6-dev-i386 is for 64 bit systems

I did not install mercurial. I downloaded source tarball instead.
from : http://golang.org/dl/
It turns out that if I had used mercurial, I could simply do pull and run all.bash to update to next version.


extract
tar -xvf go1.3.1.src.tar.gz

$ cd go/src
$ ./all.bash

It said all tests passed, and add bin directory to my PATH /opt/go/source/go/bin

Added following line to my ~/.bashrc

    PATH=$PATH:/opt/go/source/go/bin

tested hello.go
"hello, world!"

Install go tools (need mercurial installed)
go get code.google.com/p/go.tools/cmd/godoc

Setting up environment
----------------------

Following : http://golang.org/doc/code.html
 - explains the standard way to fetch, build, and install Go packages and commands
