| # 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. 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). |
| |
| ### Windows |
| |
| Windows XP (w/ Service Pack 2) or higher. But we don't currently (2016-09-23) have a Windows XP running. That is https://github.com/golang/go/issues/10267 |
| |
| We run builders testing Go on Windows Server 2008 R2 Datacenter Edition. That is basically Windows 7 or above. |
| |
| ### [macOS (née OS X, aka Darwin)](Darwin) |
| |
| macOS Sierra (10.12) requires Go 1.7.1. We have not yet (as of 2016-09-23) backported the time system call fixes to any earlier Go versions. See https://github.com/golang/go/issues/16352. |
| |
| Go only supports OS X 10.8 (Mountain Lion) or newer. We only have builders for 10.8, 10.10, and 10.11 as of 2016-09-23. |
| |
| Go tip doesn't compile on OS X 10.7 (Lion) but binaries MAY work there. Maybe. No builders, no promises. We don't recommend it. |
| |
| OS X 10.6 (Snow Leopard) is explicitly unsupported. See https://github.com/golang/go/issues/9511 |
| |
| ### [OpenBSD](OpenBSD) |
| |
| The current officially supported -stable versions only. See https://golang.org/wiki/OpenBSD for details. |
| |
| ### [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 8 and up according to https://golang.org/doc/install, but I suspect we might need something newer than 8. FreeBSD 9.1 reportedly does not work. We only run builders testing FreeBSD 9.3, FreeBSD 10.1 and 11.0. |
| |
| ### [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 |
