Setting up Golang development environment under Ubuntu

Golang Installation and Configuration

Download the installation file, currently the latest version is 1.4.2,go1.4.2.linux-amd64.tar.gz.

Extract the installation files to the specified directory:

1 sudo tar -zxvf go1. 4.2. Linux-amd64. tar. Gz-c/usr/local/

Edit the/etc/profile file to add an environment variable:

Export Goroot=/usr/local/goexport gobin= $GOROOT/binexport path= $PATH: $GOBINexport gopath= $HOME/goproj

Recompile the/etc/profile file and try to view the go version:

1 # source/etc/Profile2 # Go version

Golang Cross-compiling

Create a new Hello.go file with the following contents:

 1  package main  2  import ( 4   fmt   " 5  )   7  func Main () { 8  fmt . Println ( hello golang!   " )  9 } 

The go installation package only packages the compilation tools under the corresponding platform, for cross-compiling, you need to manually build the other platform's compilation tools. The following generates the Windows 64-bit compiler, opens/usr/local/go/src/, executes the following code, GOOS represents the target system type, Goarch indicates that the target system is 32-bit (386) or 64-bit (AMD64):

1 # sudo goos=windows goarch=amd64./make.bash

After the command executes successfully, the compiler tool for the appropriate platform is generated under/usr/local/go/pkg/.

Next, select the corresponding target platform in Liteide, compile the Go program code, the result is as follows:

Finally attach each platform GOOS and Goarch reference:

GOOS	Goarch	OS
Linux	386/amd64/arm	>= Linux2.6
Darwin	386/amd64	OS X (Snow Leopard + Lion)
Freebsd	386/amd64	>= FreeBSD 7
Windows	386/amd64	>= Windows 2000
