Linux	Go1.4.linux-amd64.tar.gz
Mac	Go1.4.darwin-amd64-osx10.8.pkg
Freebsd	Go1.4.freebsd-amd64.tar.gz

Unix/linux/mac OS X, and FreeBSD installation

The following describes the use of the source installation method under Unix/linux/mac OS X, and FreeBSD systems:

1, download the source package: go1.4.linux-amd64.tar.gz.

2. Extract the downloaded source package to the/usr/local directory.

Tar-C/usr/Local -XZF go1.4.linux-AMD64.Tar.GZ

3. Add the/usr/local/go/bin directory to the PATH environment variable:

ExportPATH=$PATH:/usr/Local/Go/bin

Note: Under MAC system you can use the. Pkg end of the installation package directly double-click to complete the installation, the installation directory under/usr/local/go/.

Installation under Windows system

Windows can be installed under an installation package that uses the. msi suffix (which can be found in the download list for the file, such as Go1.4.2.windows-amd64.msi).

By default, the. msi file is installed in the C:\Go directory. You can add the C:\Go\bin directory to the PATH environment variable. You will need to restart the Command window to take effect after adding.

File name: Test.go, the code is as follows:

 PackageMainImport "FMT"Func main() {FMT.Println("Hello, world!.")}

Use the GO command to execute the above code output as follows:

C:\go_workspace>Go Run test.GoHello,  World!
