golang package deployment win

In today's era of rapid development of the Internet, Golang (also known as Go) has become the programming language of choice for more and more developers. It is favored by many companies because of its easy-to-learn, efficient and reliable features.

However, during the Golang development process, packaging and deploying programs may be difficult for beginners, especially on Windows operating systems. Starting from this article, we will explore how to use Golang to package and deploy Windows systems.

Commonly used tools for Golang packaging and deployment

On Windows systems, we generally use the following two tools to package and deploy Golang programs:

1. golang package deployment win

Mingw-w64 is a toolset under Windows for creating 64-bit programs that run on Microsoft Windows. It is an open source programming toolset for use under Microsoft Windows, including compilers, header files, library files, etc.

2. MinGW-w64 gcc

MinGW-w64 gcc is an important part of Mingw-w64. It is a Windows platform development tool based on the gcc compiler.

Install related tools

First, we need to install MinGW-w64, MinGW-w64 gcc and Git tools. Here we take the 64-bit Windows operating system as an example. The following is the specific installation process:

1. MinGW-w64:

Open the Mingw-w64 website (golang package deployment win .org) and select the version appropriate for your computer.

After clicking the download link, select the appropriate version. Here we select the stable version (Stable Release) and enter the download page.

After the download is complete, run the installation program and follow the prompts to install.

2. MinGW-w64 gcc:

Mingw-w64 gcc can compile management and static link programs under Windows. It can completely replace GNU under Windows platform. We can download the installation file from the following website: http://sourceforge.net/projects/golang package deployment win/files/golang package deployment win/golang package deployment win-release/.

3. Git:

Since we need to download the source code of Golang, we need to install the Git tool.

Download the installation package from the Git official website and install it according to the prompts.

Compile Golang source code under Windows

After installing the relevant tools, we now need to download the Golang source code. Open the command prompt (cmd) and enter the following command:

go get -d github.com/golang/go

After executing the above command, the Golang source code will be downloaded to the GOPATH directory on your computer.

Next, we need to manually set the following three environment variables:

1. GOROOT: It specifies the installation directory of Golang.
2. GOPATH: It specifies the storage directory of the Golang project.
3. PATH: It specifies the relevant executable files that require the above two directories.

Enter the following command to set the environment variable:

setx GOROOT $env:GOPATHsrcgithub.comgolanggo
setx GOPATH %userprofile%go
setx PATH "$env:PATH;$env:GOROOTin;$env:GOPATHin"

Next, we need to enter the following command at the command prompt to compile:

cd %GOPATH%srcgithub.comgolanggosrc
mingw32-make.bat

At this time, Golang source code will be compiled in the current command prompt.

Package the Golang program into a Windows executable file

Next, we can use the gcc tool of MinGW-w64 to package the program into a Windows executable file.

1. Prepare the main.go file

We assume that you are already under GOPATH and create the following directories and files in sequence:

src
└── myexe
    └── main.go

main.go file content As follows:

package main

import (
   "fmt"
   "os"
)

func main() {
   fmt.Println("Hello,World!")
   fmt.Println(os.Args[0])
}

2. Compile the executable file

Enter the following command at the command prompt:

cd %GOPATH%srcmyexe
go build -ldflags="-s -w" -o myexe.exe main.go

The above command will compile and package it into an executable file File myexe.exe. Among them, the -s and -w parameters are used to remove debugging and symbol information respectively, thereby reducing the size of the executable file.

3. Run the executable file

In the command prompt, enter the following command to run the executable file:

myexe.exe

The following results will be output:

Hello,World!
E:gosrcmyexemyexe.exe
