Click the link above to visit the

and select the binary distribution that matches your operating system and

processor architecture.
|
|
</p>
|
|
|
|
<p>
|
|
Official binary distributions are available for the FreeBSD, Linux, Mac OS X
|
|
(Snow Leopard, Lion, and Mountain Lion), NetBSD, and Windows operating systems
|
|
and the 32-bit (<code>386</code>) and 64-bit (<code>amd64</code>) x86 processor
|
|
architectures.
|
|
</p>
|
|

If a binary distribution is not available for your combination of operating
|
|
system and architecture you may want to try

<a href="/doc/install/source">installing from source</a> or
|
|
<a href="/doc/install/gccgo">installing gccgo instead of gc</a>.

<p>
|
|
The <code>gc</code> compiler supports the following operating systems and
|
|
architectures. Please ensure your system meets these requirements before
|
|
proceeding. If your OS or architecture is not on the list, it's possible that
|
|
<code>gccgo</code> might support your setup; see
|
|
<a href="/doc/install/gccgo">Setting up and using gccgo</a> for details.

<sup>†</sup><code>gcc</code> is required only if you plan to use

<a href="/cmd/cgo">cgo</a>.<br/>
|

<sup>‡</sup>You only need to install the command line tools for
|
|
<a href="http://developer.apple.com/Xcode/">Xcode</a>. If you have already

installed Xcode 4.3+, you can install it from the Components tab of the

Downloads preferences panel.

|
<h2 id="install">Install the Go tools</h2>
|
|
|
|
<p>
|
|
The Go binary distributions assume they will be installed in
|
|
<code>/usr/local/go</code> (or <code>c:\Go</code> under Windows),
|
|
but it is possible to install them in a different
|
|
location. If you do this, you will need to set the <code>GOROOT</code>
|
|
environment variable to that directory when using the Go tools.
|
|
</p>
|
|
|
|
<p>
|
|
For example, if you installed Go to your home directory you should add the
|
|
following commands to <code>$HOME/.profile</code>:
|
|
</p>
|
|
|
|
<pre>
|
|
export GOROOT=$HOME/go
|
|
export PATH=$PATH:$GOROOT/bin
|
|
</pre>
|
|
|
|
<p>
|
|
Windows users should read the section about <a href="#windows_env">setting
|
|
environment variables under Windows</a>.
|
|
</p>
|
|
|
|
<h3 id="bsd_linux">FreeBSD, Linux, Mac OS X and NetBSD tarballs</h3>
|
|
|
|
<p>
|
|
If you are upgrading from an older version of Go you must
|
|
first remove the existing version from <code>/usr/local/go</code>:
|
|
</p>
|
|
|
|
<pre>
|
|
rm -r /usr/local/go
|
|
</pre>
|
|
|
|
<p>
|
|
Extract <a href="http://code.google.com/p/go/downloads/list?q=OpSys-FreeBSD+OR+OpSys-Linux+OR+OpSys-OSX+OR+OpSys-NetBSD+Type-Archive">the archive</a>
|
|
into <code>/usr/local</code>, creating a Go tree in <code>/usr/local/go</code>.
|
|
For example:
|
|
</p>
|
|
|
|
<pre>
|
|
tar -C /usr/local -xzf go1.1.linux-amd64.tar.gz
|
|
</pre>
|
|
|
|
<p>
|
|
The name of the archive may differ, depending on the version of Go you are
|
|
installing and your system's operating system and processor architecture.
|
|
</p>
|
|
|
|
<p>
|
|
(Typically these commands must be run as root or through <code>sudo</code>.)
|
|
</p>
|
|
|
|
<p>
|
|
Add <code>/usr/local/go/bin</code> to the <code>PATH</code> environment
|
|
variable. You can do this by adding this line to your <code>/etc/profile</code>
|
|
(for a system-wide installation) or <code>$HOME/.profile</code>:
|
|
</p>
|
|
|
|
<pre>
|
|
export PATH=$PATH:/usr/local/go/bin
|
|
</pre>
|
|
|
|
<h3 id="osx">Mac OS X package installer</h3>
|
|
|
|
<p>
|
|
Open the <a href="http://code.google.com/p/go/downloads/list?q=OpSys-OSX+Type-Installer">package file</a>
|
|
and follow the prompts to install the Go tools.
|
|
The package installs the Go distribution to <code>/usr/local/go</code>.
|
|
</p>
|
|
|
|
<p>
|
|
The package should put the <code>/usr/local/go/bin</code> directory in your
|
|
<code>PATH</code> environment variable. You may need to restart any open
|
|
Terminal sessions for the change to take effect.
|
|
</p>
|
|
|
|
<h3 id="windows">Windows</h3>
|
|
|
|
<p>
|
|
The Go project provides two installation options for Windows users
|
|
(besides <a href="/doc/install/source">installing from source</a>):
|
|
a zip archive that requires you to set some environment variables and an
|
|
experimental MSI installer that configures your installation automatically.
|
|
</p>
|
|
|
|
<h4 id="windows_zip">Zip archive</h4>
|
|
|
|
<p>
|
|
Extract the <a href="http://code.google.com/p/go/downloads/list?q=OpSys-Windows+Type%3DArchive">zip file</a>
|
|
to the directory of your choice (we suggest <code>c:\Go</code>).
|
|
</p>
|
|
|
|
<p>
|
|
If you chose a directory other than <code>c:\Go</code>, you must set
|
|
the <code>GOROOT</code> environment variable to your chosen path.
|
|
</p>
|
|
|
|
<p>
|
|
Add the <code>bin</code> subdirectory of your Go root (for example, <code>c:\Go\bin</code>) to your <code>PATH</code> environment variable.
|
|
</p>
|
|
|
|
<h4 id="windows_msi">MSI installer (experimental)</h4>
|
|
|
|
<p>
|
|
Open the <a href="http://code.google.com/p/go/downloads/list?q=OpSys-Windows+Type%3DInstaller">MSI file</a>
|
|
and follow the prompts to install the Go tools.
|
|
By default, the installer puts the Go distribution in <code>c:\Go</code>.
|
|
</p>
|
|
|
|
<p>
|
|
The installer should put the <code>c:\Go\bin</code> directory in your
|
|
<code>PATH</code> environment variable. You may need to restart any open
|
|
command prompts for the change to take effect.
|
|
</p>
|
|
|
|
<h4 id="windows_env">Setting environment variables under Windows</h4>
|
|
|
|
<p>
|
|
Under Windows, you may set environment variables through the "Environment
|
|
Variables" button on the "Advanced" tab of the "System" control panel. Some
|
|
versions of Windows provide this control panel through the "Advanced System
|
|
Settings" option inside the "System" control panel.
|
|
</p>
|
|
|
|
<h2 id="testing">Test your installation</h2>
|
|
|
|
<p>
|
|
Check that Go is installed correctly by building a simple program, as follows.
|
|
</p>
|
|
|
|
<p>
|
|
Create a file named <code>hello.go</code> and put the following program in it:
|
|
</p>
|
|
|
|
<pre>
|
|
package main
|
|
|
|
import "fmt"
|
|
|
|
func main() {
|
|
fmt.Printf("hello, world\n")
|
|
}
|
|
</pre>
|
|
|
|
<p>
|
|
Then run it with the <code>go</code> tool:
|
|
</p>
|
|
|
|
<pre>
|
|
$ go run hello.go
|
|
hello, world
|
|
</pre>
|
|
|
|
<p>
|
|
If you see the "hello, world" message then your Go installation is working.
