| ## 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. |
