How to set up exe in golang

On the Windows platform, golang executable files usually end with exe. For developers who want to compile golang programs into exe files for deployment, further settings and configurations may be required.

1. Install the Go compiler

First, make sure you have the Go compiler installed. You can go to the official website (https://golang.org/dl/) to download and install the latest version of the Go compiler. After the installation is completed, the Go installation path will be automatically added to the PATH environment variable.

2. Write the code and build it

Next, write the code and build it. Suppose we have written a program called hello.go and want to compile it into an exe file.

In the command line, switch to the directory where hello.go is located and execute the following command:

go build -o hello.exe hello.go

This command will generate a file named hello.exe in the current directory. executable file.

3. Configure environment variables

If you want to use the hello.exe file globally, you can add it to the system's PATH environment variable. First, press Win R to open the run window, enter "sysdm.cpl" and press the Enter key. Next, click the "Advanced" tab in the pop-up system properties window, and then click the "Environment Variables" button. In the environment variables window, double-click the "Path" variable, click the "New" button, enter the directory path where the hello.exe file is located, and confirm to save. After this, you can run the hello.exe file anywhere.

4. Use packaging tools

In addition to manually configuring environment variables, we can also use packaging tools to package golang programs into executable files. The packaging tool can package related dependencies into the same folder at the same time to facilitate migration and deployment.

Commonly used packaging tools include:

• GoReleaser: has become one of the popular tools in the golang community, supporting the construction of code corresponding to multiple platforms such as Linux, Windows, macOS, etc. Binary packages and various packaging formats such as tar.gz and zip;
• Statik: can package applications and static files into a single binary file;
• pkger: similar to Statik, can package static resources Embed into binary files, supporting go embed feature.

Using packaging tools can make the migration and deployment of golang programs easier and more convenient.

Summary

The above are the methods and techniques on how to set up the exe executable file of the golang program. Through these methods, we can better deploy golang applications to different platforms. Whether it is manual configuration or using packaging tools, our golang program can be made more scalable and portable.
