Golang Environment Construction

This is a creation in Article, where the information may have evolved or changed. Operating system Ubuntu 12.04 64-bit

1. Configuring the compilation Environment

The Go tool chain is written in C and needs to be installed with the following development tools

$ sudo apt-get install bison gcc libc6-dev ed gawk make

2. Installing the Mercurial tool

Mercurial is a lightweight distributed version control system, written in Python.

First install Python

$ sudo apt-get install python2.7

$ sudo apt-get install Python-all-dev

$ sudo apt-get install Python-setuptools

Installing mercurial

$ sudo easy_install-u Mercurial

Test the following after the installation is complete

$ hg-v

3. Get Go Source

$ HG Clone-u Release Https://go.googlecode.com/hg/go

4. Compiling the source code

$ CD GO/SRC
$./all.bash


5. Configure environment variables after successful compilation

$ sudo gedit ~/.BASHRC


Add the following content:

#golang
Export Goroot=~/go
Export GOARCH=AMD64
Export Goos=linux
Export gobin= $GOROOT/bin
Export gotool= $GOROOT/pkg/tool/linux_amd64
Export path= $PATH: $GOBIN: $GOTOOL

Where Pkg/tool/linux_amd64 is the location of the 6g 6l tool.

6. Testing

The Test.go file code is as follows

Package Main

Import "FMT"

Func Main () {
Fmt. Printf ("Hello, world\n")
}



Compiling, linking, executing

$6g Test.go
$ ls
Test.6 Test.go
$6l test.6
$ ls
6.out test.6 Test.go
$./6.out
Hello, world

Or just run go run test.go

The Ps:go compiler supports three instruction sets, and the code quality generated by different architectures differs:

AMD64 (a.k.a.x86-64) 6g 6l 6c 6a The most mature implementations, the compiler optimizes at the register level, producing high-quality target code.

386 (a.k.a.x86 or x86-32) 8g 8l 8c 8a AMD64 full porting

Arm (a.k.a.arm) 5g 5l 5c 5a
