Description

This article requires more than 1.5 cross-compiling

Golang MAC to compile Windows 64

➜  ~CGO_ENABLED=0 GOOS=windows GOARCH=amd64 go build -o test_win_x64.exe test.go

Linux 64 support under Golang MAC

➜  ~CGO_ENABLED=0 GOOS=linux GOARCH=amd64 go build -o test_linux_x64 test.go

Prepare a cross-compilation environment

Mac or Linux Preparation

Because go after 1.5 has used Golang 1.4来 to compile itself (bootstrap), so need to download golang1.4 first

Windows Ready

Download

Need to download 32 and 64 install TDM-GCC 32 bit 64 bit and set path

After decompression
Set environment variables GOROOT_BOOTSTRAP to extract directory (prohibit any Chinese, coding problems)

Go to the directory where you want to configure cross-compilation, execute

cd %GOROOT%/srcset CGO_ENABLED=0 | set GOOS=linux | set GOARCH=amd64 | make.bat

Golang Cross-platform cross-compilation

• Need to enter the $GOROOT/go/src directory where the source code executes
• Requires a Golang 1.4.x environment

# 如果你想在Windows 32位系统下运行➜  ~cd $GOROOT/src➜  ~CGO_ENABLED=0 GOOS=windows GOARCH=386 ./make.bash# 如果你想在Windows 64位系统下运行➜  ~cd $GOROOT/src➜  ~CGO_ENABLED=0 GOOS=windows GOARCH=amd64 ./make.# 如果你想在OS X 32位系统下运行➜  ~cd $GOROOT/src➜  ~CGO_ENABLED=0 GOOS=darwin GOARCH=386 ./make.bash# 如果你想在OS X 64位系统下运行➜  ~cd $GOROOT/src➜  ~CGO_ENABLED=0 GOOS=darwin GOARCH=amd64 ./make.bash# 如果你想在Linux 32位系统下运行➜  ~cd $GOROOT/src➜  ~CGO_ENABLED=0 GOOS=linux GOARCH=386 ./make.bash# 如果你想在Linux 64位系统下运行➜  ~cd $GOROOT/src➜  ~CGO_ENABLED=0 GOOS=linux GOARCH=amd64 ./make.bash

You can use cross-compilation only after execution finishes

Not to recompile go, because when you install go, you just compile what the local system needs, and cross-platform cross-compilation, you need to add support for other platforms in go, so there's ./make.bash a process

Error Set $GOROOT _bootstrap

• cgo_enabled = 0 indicates that the settings CGO tool is not available
• GOOS the target operating system of the program build environment
• Goarch represents the target computing architecture of the program build environment
