golang compilation

Cross-platform

GOOS=linux GOARCH=amd64 go build <packageName>

Conditional compilation

• Conditional compilation c not go as defined by the macro can implement conditional compilation of the code within a file, he only supports file-level
• Method One: Compile tab of the beginning of the file
  • Note that the label needs to compile and package declaration (package main) a space, otherwise it will be treated as a comment statement
  • All conditions in the row for the relationship or
  • Conditions for the relationship between each row and the

// +build dawin freebsd

// +build ！linux

• Cross-platform above is automatically triggered, we can also manually trigger a number of conditional compilation

  • Automatic selection json parsing library

• Method Two: file extension

  • If your source files contain suffix: $ GOOS.go, then the source file will only be compiled under the platform, $ GOARCH.go as well.
  • These two suffixes can be used together, but to pay attention to the order : $ GOOS $ GOARCH.go, in turn, can not be used: $ GOARCH $ GOOS.go
