| # Minimum Requirements |
| |
| ## Operating Systems |
| |
| ### [Linux](Linux) |
| |
| Kernel version 2.6.23 or later. [_This depends on architecture though, we need to have specific builder for this._] Linux/ARMv5 requires much newer kernels, at least v3.1 (for `__kuser_cmpxchg64`). |
| |
| We don't support CentOS 5. The kernel is too old (2.6.18). |
| |
| For little-endian MIPS64, kernel version [4.1 is known to fail, and 4.8 works](https://golang.org/issue/16848). |
| |
| If you are using tinyconfig (e.g. make tinyconfig) for embedded systems, you will also almost certainly enable printk in the kernel as well as a console; we will not include those generic options here. For Go, you must also enable CONFIG_FUTEX. |
| |
| ### [Windows](Windows) |
| |
| For Go 1.10: Windows XP (w/ Service Pack 3) or higher. |
| |
| For Go 1.11 and later: Windows Server 2008R2 and higher or Windows 7 and higher. We test on Windows Server 2008 R2, 2012 R2, and 2016, which are roughly Windows 7, Windows 8, and Windows 10. |
| |
| ### [macOS (née OS X, aka Darwin)](Darwin) |
| |
| macOS Sierra 10.12 or higher requires Go 1.7.1 or above. |
| Go only supports OS X 10.8 Mountain Lion or newer. We only have builders for 10.10, and 10.11 as of 2018-02-16. |
| |
| ### [OpenBSD](OpenBSD) |
| |
| The current officially supported -stable versions only. |
| |
| ### [DragonFly BSD](DragonFly-BSD) |
| |
| Generally only the latest release version only. We have a builder, but it's not the most stable of our ports. |
| |
| ### [FreeBSD](FreeBSD) |
| |
| FreeBSD 10 or higher, but FreeBSD 12-CURRENT is [not supported](https://github.com/golang/go/issues/22447). |
| We only run builders testing FreeBSD 10.3 and 11.1. |
| |
| ### [NetBSD](NetBSD) |
| |
| There are known NetBSD bugs (including kernel crashes) up to the current NetBSD 7.1. There is a reported fix in NetBSD 7.1.1 but it's unverified as of 2017-07-10, as we're not running builders again yet. See https://tip.golang.org/doc/go1.9#known_issues and https://github.com/golang/go/issues/20852 |
| |
| ### [Native Client](NativeClient) |
| |
| pepper_39 or newer. |
| |
| ### [Solaris](Solaris) |
| |
| illumos (former OpenSolaris 10) based distributions or Oracle Solaris 11+. |
| |
| ## Architectures |
| |
| ### amd64 |
| |
| All 64-bit x86 processors. |
| |
| ### 386 |
| |
| See https://golang.org/doc/install/source#environment |
| |
| * GO386=387: run on any Pentium MMX or later processor. |
| * GO386=sse2: run on any processor with at least SSE2 (the default). |
| |
| ### arm |
| |
| See https://golang.org/doc/install/source#environment |
| |
| * GOARM=5: use software floating point; when CPU doesn't have VFP co-processor |
| * GOARM=6: use VFPv1 only; default if cross compiling; usually ARM11 or better cores (VFPv2 or better is also supported) |
| * GOARM=7: use VFPv3; usually Cortex-A cores |
| |
| ### arm64 |
| |
| All ARMv8-A processors. |
| |
| ### ppc64 (big endian) |
| |
| POWER5 and above. |
| Starting with Go 1.9, only POWER8 and above are supported. |
| |
| ### ppc64le (little endian) |
| |
| POWER8 and above. |
| |
| ### mips64 (big endian) |
| |
| MIPS III or higher. Builder is using MIPS64r2. |
| |
| ### mips64le (little endian) |
| |
| MIPS III or higher in little endian mode. Builders are using Loongson 2E/2F. |
| |
| ### s390x |
| |
| z196+ |
| |
| ### mips (big endian) and mipsle (little endian) |
| |
| MIPS32r1, with FPU or kernel FPU emulation |
