## Cross-compile for your server
If your server runs a different OS or has a different CPU than your build
machine, you will need to recompile the binary for the server.
For a Linux server with an Intel or AMD CPU:
CGO_ENABLED=0 GOOS=linux GOARCH=amd64 go build -ldflags='-s -w'
For a Raspberry Pi 1:
CGO_ENABLED=0 GOOS=linux GOARCH=arm GOARM=6 go build -ldflags='-s -w'
For a BeagleBone or a Raspberry Pi 2 or later:
CGO_ENABLED=0 GOOS=linux GOARCH=arm GOARM=7 go build -ldflags='-s -w'
For a 64-bit ARM board (Olimex Olinuxino-A64, Pine64, etc.):
CGO_ENABLED=0 GOOS=linux GOARCH=arm64 go build -ldflags='-s -w'
For a 32-bit MIPS board with no hardware floating point (WNDR3800, etc.):
CGO_ENABLED=0 GOOS=linux GOARCH=mips GOMIPS=softfloat go build -ldflags='-s -w'
