How to compile golang

With the development of computer science and technology, the world of software development is also constantly changing and progressing. In recent years, a programming language called Golang has become more and more popular among developers. Because of its advantages such as efficiency, speed, and simplicity, it has become a leader among modern programming languages. This article will explore various methods and techniques of Golang compilation.

Golang is a programming language developed by Google. Due to its advantages such as efficiency, speed, and simplicity, more and more companies and developers are beginning to use this emerging technology. Golang has a compiler-based operating mode, which means that when programming with Golang, the source code must be compiled into an executable binary file before it can be run and deployed. In this article, we will discuss how to use Golang’s compiler to compile program source code into executable binaries.

1. IDE integrated compilation

Mainstream IDE integrated development environments all support Golang compilation. For example: VSCode, Sublime Text, Atom, GoLand, IDEA, Eclipse, NetBeans, etc. To use these IDEs, you only need to follow the corresponding plug-ins or configurations to complete the compilation process. The more common ones are the use of VSCode and GoLand editors.

Compile using VSCode:

1. Install VSCode

2. Search for the "Go" plug-in in the extension. After the installation is complete, it can support automatic formatting of Golang code. Code jump, code highlighting, code completion, compilation and running and other functions.

3. To configure the Golang project, you can use the command line "go mod init project name" command to initialize the current project to solve package dependency issues. Enter the project root directory and select the "run" button or the command line "go build" to compile and run.

Compile using GoLand:

1. Install GoLand

2. After starting GoLand, click "New Project" in the left column and select the "Go Modules" option. Initialize the current project to facilitate management of its dependencies. After creation, create or open the go file under the current project to complete code editing and automatic completion.

3. Compile and run the Golang project. Select the file to be compiled and use the built-in shortcut keys of the IDE to directly compile and run.

2. Use the command line to compile

If you don’t like to use IDE, or your personal habits can get rid of the constraints of IDE, then you can implement Golang compilation through the command line.

Open the command line window, enter the directory where the source code is located, and execute the "go build" command to complete the compilation operation. By default, the Go compiler will compile all go files in the current directory into executable binary files with the name of the current directory. If you want to customize the name of the generated executable file, you can use the "-o" option to specify the output binary file name, for example:

$go build -o app.exe

in Here, we used the "-o" option to specify the name of the output file as "app.exe".

If you want to compile multiple go files at the same time and maintain their relative position relationship, you can create a folder in the current directory and put all related files in it so that they can be specified during compilation The location, for example:

$go build -o main ./src/*

At this time, we will compile the "main.go" file in the current directory, and its dependencies are located "src" folder.

3. Compile using Docker

In addition to using IDE and command line tools, Docker is also a powerful tool that can help us complete the task of Golang compilation. Docker can put code and compilation environment in a virtual container for compilation and deployment in different environments. Using Docker for compilation can greatly simplify the compilation process, reduce the burden on developers, and also ensure the consistency of the compilation environment.

The steps are as follows:

1. Install Docker on the host

2. Create a Golang project and upload it to GitLab, GitHub and other code repositories. This is Docker Code required during the build process.

3. Create a Dockerfile to build the Golang compiled image.

FROM golang:latest
COPY . /app
WORKDIR /app
RUN go build -o main .
CMD ["/app/main"]

4. Execute docker build to build the image and Docker running steps.

$docker build -t go_builder

5. Steps to run using Docker:

$docker run --rm -it -v $(pwd):/app/spawn go_builder

$(pwd) here represents the current directory and is used when specifying the output file name. In this way, the specified executable file will be generated in the current directory.

The above are the compilation methods and techniques of Golang. Choose the appropriate method to compile according to your own needs and habits!
