## Introduction

This is a companion to https://go.dev/doc/install/source providing additional instructions for various operating systems.

## Install C tools

On OS X, a C compiler is bundled in the command line tools for
[Xcode](http://developer.apple.com/Xcode/),
and you don't need to install the whole Xcode to compile Go.
If you have already installed Xcode 4.3+, you can install command
line tools from the Components tab of the Downloads preferences panel.
In more recent versions of Xcode, you can use `xcode-select --install`
command to install the command line tools without opening Xcode.
To verify you have a working compiler, just invoke `gcc`
in a freshly created Terminal window, unless you see the
`"gcc: command not found"` error, you are ready to go.

On Ubuntu/Debian, use `sudo apt-get install gcc libc6-dev`.
If you want to build 32-bit binaries on a 64-bit system you'll also need the `libc6-dev-i386` package.

On RedHat/Centos 6, use `sudo yum install gcc glibc-devel`.
If you want to build 32-bit binaries on a 64-bit system you'll need both
`glibc-devel.i386` and `glibc-devel.x86_64` packages.

On Windows, install `gcc` with
[TDM-GCC](http://tdm-gcc.tdragon.net/). or try [TDM-GCC Sourceforge link](https://sourceforge.net/projects/tdm-gcc/).
(Make sure you add its `bin` subdirectory to your `PATH`.) Go does not support the Cygwin toolchain.
