Golang Cross-compiling

This is a created article in which the information may have evolved or changed.

Go is a compiled language, so on different platforms, you need to compile and generate binary packages of different formats.

Because go 1.5 has some improvements to cross-platform compilation, including a unified compiler, linker, and so on.
Compile time only need to specify two parameters: GOOS and GOARCH can.

Example:

# 编译到 linux 64bit$ GOOS=linux GOARCH=amd64 go build# 或者可以使用 -o 选项指定生成二进制文件名字$ GOOS=linux GOARCH=amd64 go build -o app.linux# 编译到 linux 32bit$ GOOS=linux GOARCH=386 go build# 编译到 windows 64bit$ GOOS=windows GOARCH=amd64 go build# 编译到 windows 32bit$ GOOS=windows GOARCH=386 go build# 编译到 Mac OS X 64bit$ GOOS=darwin GOARCH=amd64 go build
