go 常用命令记录

交叉编译

1. 在mac上编译64位linux, Windows的命令编译命令

# Linux
CGO_ENABLED=0 GOOS=linux GOARCH=amd64 go build filename.go
 
# Windows
CGO_ENABLED=0 GOOS=windows GOARCH=amd64 go build filename.go
#如: CGO_ENABLED=0 GOOS=windows GOARCH=amd64 go build -o helloworld-windows helloworld.go

2. 在windows 上编译64位linux的命令编译命令

CGO_ENABLED=0 GOOS=linux GOARCH=amd64 go build -o ./main ./main.go

3. Linux下编译Mac, Windows

# Mac
CGO_ENABLED=0 GOOS=darwin GOARCH=amd64 go build filename.go
 
# Windows
CGO_ENABLED=0 GOOS=windows GOARCH=amd64 go build filename.go
