| # Introduction |
| |
| Go programs can be cross-compiled e.g., on x86/x86\_64 build systems to run on MIPS target machines. |
| |
| # Supported architectures |
| |
| Go supports the following MIPS architectural families. (Are there more?) |
| |
| | **Architecture** | **Status** | **GOMIPS value** | **GOARCH value** | |
| |:-----------------|:-----------|:----------------|:-----------------| |
| | Big endian (e.g., ar71xx) | supported | GOMIPS=softfloat| GOARCH=mips | |
| | Little endian | supported | n/a | GOARCH=mipsle | |
| |
| # Supported operating systems |
| |
| * MIPS on Linux. Tested with an ar71xx based OpenWrt device. |
| |
| # Recommended Go version |
| |
| The tested version for running Go on MIPS systems is Go 1.13. |
| |
| # Tips and tricks |
| |
| ## Building for ar71xx OpenWrt |
| |
| This builds a Go program, strips unneeded strings and symbols to minimize its size, and compresses it to further minimize its size: |
| |
| ``` |
| env GOOS=linux GOARCH=mips GOMIPS=softfloat go build -trimpath -ldflags="-s -w" 'server.go' |
| upx -9 server |
| ``` |
| |
| # Success stories |
| |
| MIPS hardware comes in a myriad of shapes and sizes. If you've had a success story building and running Go on your Arm system, please detail your results here. |

| ## D-Link DIR-505 Mobile Companion |
| |
| Architecture: ar71xx |
| |
| Operating System: OpenWrt |
| |
| The D-Link DIR-505 Mobile Companion comes with an Atheros AR1311 processor, 8 MB flash and 64 MB RAM. This space is limited but allows us to load Go applications, e.g., from network into `/tmpfs` and execute them from there. |
