The go build command in the Go programming language is used to compile Go source code files into executable binaries or shared libraries. This command is part of the Go toolchain and is helpful in developing and deploying Go applications. Here is a brief description of the go build command:
# go build [build flags] [packages]
The go build command accepts various build flags that allow users to customize the compilation process. These flags control aspects like optimization, platform targeting, and more.
“go build” command example
1. Compile a 'package main' file (the output will be the file name without extension):
# go build /path/to/main.go
2. Compile specifying the output file name:
# go build -o /path/to/binary /path/to/source.go
3. Compile a package:
# go build -o /path/to/binary /path/to/package
4. Compile a main package into an executable with data race detection enabled:
# go build -race -o /path/to/executable /path/to/main/package
The Go build command is a fundamental tool in the Go development workflow, allowing developers to compile their code into executable binaries that can be run on a variety of platforms. It is versatile and can be adapted to suit different compilation needs.
