| # Minimum Requirements |
| |
| ## Operating Systems |
| |
| ### Linux |
| |
| Kernel version 2.6.23 or later. [_This depends on architecture though, we need to have specific builder for this._] |
| |
| We don't support CentOS 5. Kernel is too old (2.6.18). |
| |
| ### Windows |
| |
| Windows XP 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) |
| |
| macOS Sierra (10.12) requires Go 1.7. 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 (Snow Leopard) or newer. We only have builders for 10.8, 10.10, and 10.11 as of 2016-09-23. |
| |
| Go tip doesn't compile OS X 10.7 but binaries MAY work there. Maybe. No builders, no promises. We don't recommend it. |
| |
| OS X 10.6 is explicitly unsupported. See https://github.com/golang/go/issues/9511 |
| |
| ### OpenBSD |
| |
| The current officially supported -stable versions only. |
| |
| ### DragonFly |
| |
| Generally only the latest release version only. We have a builder, but it's not the most stable of our ports. |
| |
| ### FreeBSD |
| |
| FreeBSD 8 and up according to https://golang.org/doc/install, but I suspect we might need something newer than 8. |
| |
| ### Native Client |
| |
| pepper_39 or newer. |
| |
| ### Solaris |
| |
| illumos (former OpenSolaris 10) based distributions or Oracle Solaris 11+. |
| |
| ## Architectures |
| |
| ### x86 |
| |
| See https://golang.org/doc/install/source#environment |
| |
| Set GO386=387 or GO386=sse2 for older processors. |
| |
| ### 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) |
| |
| PPC 970 or newer. |
| |
| ### ppc64le (little endian) |
| |
| POWER8+ |
| |
| ### 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+ |
